Learn About J2ME


2010
12.14

The more advanced technological developments, especially in the mobile world, leading to the popular J2ME platform. Besides easy access to both CDMA and GSM mobile phones, J2ME is also supported by many major manufacturers, like Nokia, Sony Ericsson, Motorola and many more. Why J2ME widely used? And what the heck it is J2ME?

J2ME (Java 2 Platform, Micro Edition) or now known as JME is an abbreviation of the Java Micro Edition. From the stands it was to us a single java analysis that is designed specifically for small devices such as mobile or devices that have limited capabilities. Java ME is made in order to be able to run and perform almost any task that was done on desktops requires a standard and simple way to develop applications on devices that have limitations like small screens, limited memory, slow processors and others. Java ME was designed by Sun Microsystems which is a subsidiary of Oracle Corporation. JME or J2ME is one of the three editions of Java technology, the other editions of the J2EE server addressed to the system weight and J2SE are aimed at the Desktop Standard and workstation applications. The division is done because a size of Java will not be able get into all kinds of devices.

Why choose Mobile Application Developers Java ME or J2ME? That’s because the Java ME includes flexible user interfaces, robust security, and built-in network protocols and support for network and offline applications that can be downloaded dynamically. It consists of a number of specific components, which have been set by the industry through the Java Community Process (JCP). In addition, by using this Java tool we use to support across all platforms. Java ME itself is a simple Java API developed by the developers themselves, because it is a kind of open source and is platform independent. If the programs are designed to be written in the form of Java, the program will be run anywhere but still within the scope of Platform Independent. Developers can create modular programs and code that can be used again. Additionally the user or the developer does not need to pay a heavy license annually.

After knowing what Java ME or J2ME, and what advantages-advantages we certainly interested in how I create a program application. But before making a program we need to know Java ME compiler first. To create J2ME applications do not require complicated software and large. One of them we can use the J2SE SDK / JDK. In it there is a runtime and library for Java programs in general as well as for J2ME. In addition we also need an IDE or integrated development environment for writing source code that can be downloaded at their official websites. Immediately below the Java code is easier to learn and no more complicated than in C or C + +. Type of files generated by the J2ME JAR file and the size of the application is also not great.

The steps to create a simple application using Netbeans IDE v4.1, which I quoted from http://www.scribd.com/doc/33768913/Cara-Membuat-Aplikasi-Java is as follows:

1.       Install J2SE SDK v1.4.2 (50MB)

2.       Netbean Install v4.1 (47MB)

3.       Install netbean Mobility Pack v4.1 (18MB)

4.       Run netbean v4.1, create a new project and select the category “Mobile” and the type of project
“Mobile Application”

5.       Select the location where to save the files of this project, “Set as Main Project” and “Create
Hello MIDlet “should not be changed (checked)

6.       On the page “Platform Selection” select “Device Configuration” = CLDC-1.0 and
“Device Profile” = MIDP-1.0 (the smallest version that can be used in all cellular
which support J2ME)

7.       After all finished (tempate was created), run this application by pressing
F6 key (the Run Main Project).

8.       Then this project will compile and the emulator will be out, use the mouse to operate the emulator, by pressing the keypad button pressed dalamemulator is much like regular phones.

9.       At this time, the application “Hello World” we have made and can be completed directly on the test on the actual provider.

These applications can be tested by sending them to mobile devices that support J2ME in the usual way we use to send files from your computer as usual.

Examples of programs which I have quoted is still a simple application. We can make the application better and bigger for example making games. Therefore, when we were tired of playing those games other people’s work, we can try to make our own game. But if you want to make a game of course we also have to have a high skill of the graphic. So the games that we make not only good in terms of the game’s storyline but also good at graphic appearance. Did not rule the game of our work will also be liked by others.

For making the game we can use game builder. In manufacturing we will meet with the mainmidlet. Mainmidlet consists of 3 methods. The three methods are:

1.       startApp () is called to start the game.

2.       PauseApp () is called to pause the application, the application can proceed by resumeMIDlet call ().

3.       . DestroyApp (boolean unconditional) is called when exiting the application.

If we use neatbeans (same as we use them on a simple application example) then the method is automatically generated by creating a visual MIDlet. Display can be set on gamecanvas either at the end and inside gamecanvas by SetCurrent method. With this gamecanvas we can create an image,shape, or a string. GameCanvas This can simplify the reading of a process.

Time of a game controlled by Tick. Tick this is a integer that deal with the timer, for example, long an object will appear and how long a frame will appear. While the figures in a game called Sprite. In the manufacture of each sprite sprite made must have the same height and width on each movement except the sprites that you created in the design will have a special ability to change the form itself.

For an example of source code on the J2ME game programming can be downloaded at http://www.codeproject.com/KB/java/GameProgrammingInJ2ME/FightFight0.02.zip. java files you can open with WordPad.

Try it and Good Luck 😀

Every business is run would not completely run smoothly or without constraints. All would still need the renewal to comply with the wishes and consumer convenience in the transaction. Moreover, doing business through electronic business or also called the E-Business. Doing business with the help of the internet such as through online sales using their own blogs or sell them online through social networking sites like Facebook and others would also have many problems or obstacles that occur when we offer our merchandise items, on during the purchase transaction even when the delivery of goods and payment process.

If you do trade business only through the help of the Internet so any buyer should be able to operate and know how to buy, order until the payment process to do. In addition, the image display to provide an overview of products that we sell should be more clear because prospective buyers can not see directly the goods we offer. It certainly gives a negative impact for people who do business, lack of trust in the seller or business owner is also the difficulty of the ordering process is also a problem for a business. Because each customer can order forms or motifs and also the color of the goods (shoes) in accordance with her wishes if we do not understand exactly what is desired by the buyer then the shoes that we make will not be sold to the buyer because the order is not in accordance with their wishes. In contrast, if we immediately set up a store and receive direct orders. We can directly reflect the will of the buyer in the form of sketch drawings. So the possibility of non skewer into smaller reservations.

Take time to overcome all these problems occur. For the moment we can do is improve the existing product display, if we give opportunity to the buyer to be able to give their ideas to each reservation, we also have to give some examples of motifs that can be modified by combining motif that we provide or by customer can transmit their images via the Internet design is intended to address the company. However, this will require a longer time, because of course every buyer has a different idea.

To overcome the problems many orders of all kinds of buyers we can work around this by way of always making the product in accordance with the existing trend. Every moment must be ready with new designs. Always create a new catalog offerings and also always update the company website or blog. However, this will require more hard work from each member company to cooperate in all respects. All persons who served as the motive and the model shoe designer to be more creative and innovative. However, if it can go well then the maintenance company will be even better because it can simultaneously compete with other similar companies.

Trust purchaser of the product must also be kept, so far the problems that we often encounter is the buyer’s fear of the goods they buy do not fit when worn. This can be overcome by including the specification of the goods we offer in detail again. In addition, the payment process should we make it simple. By using simple sequences of payments in filling the questionnaire. Buyers also must list the complete address for goods ordered can more quickly arrive.

Of all the problems that exist in addition to the need to increase the performance of the provider or traders also must have good communication and cooperation between sellers and buyers to smooth the transaction process until the delivery of goods.

E-Business, E Commerce, and Artificial Intelligence


2010
11.23

At present many businesses that use Internet services in assisting the process of interaction between seller and buyer or client. This is certainly a lot of members a positive impact both for the merchant or businessman or the buyer or the client itself. Because they do not have to deal directly in this case means that each transaction does not require them to meet directly at a place to conduct transactions. If we use the internet facilities in the sale and purchase transactions as in my previous article the buyer can order goods (shoes) with an online way we will not be separated from the term E-business and E-commerce. Then, what is the meaning of E-business and E-commerce?

E-business or electronic business is a business activity carried out by using the computer information systems with the help of the Internet to enable a company associated with the system to internal and external data processing more efficient and flexible. E-Business is used to help the relationship between clients or partners with suppliers to serve customer demand so that customers get satisfaction in their transactions. While the E-Commerce or Electronic Commerce is the buying and selling activities or sale and purchase transactions are done via internet or network computer. This means that the E-Commerce is part of E-Business itself. E-commerce is also often regarded as the sales aspect of e-business.

If we conduct business using the internet services such as serving the purchasing and ordering online through the internet then it is also included in the E-Business. Meanwhile, if there are customers who book and buy the goods we sell using online reservations via the Internet means that we have been doing E-commerce.

In respect of E-Business and E-commerce is certainly a man can not do the entire job themselves by using their intelligence in all things and at the same time. Of course every activity that occurs during a transaction can not be directly done by humans alone. Therefore, humans also need the help of objects or anything else that can help in performing his duties. Therefore, artificial intelligence is very stony, in this case. Then what is the meaning of artificial intelligence itself? Artificial intelligence is the intelligence, addressed to an artificial entity. Artificial intelligence is made to do things like human beings. Intelligence was created and put into a machine or computer so that the task should be done by humans can be done by computer automatically. But artificial intelligence was created only as a helper of man in doing his job so that the human task becomes easier.

When viewed from the notion of artificial intelligence and certainly every business in the process of interaction is assisted by artificial intelligence suppliers do not necessarily have to work very hard both in terms of serving the customer and in terms of computation because it can be done either by a device that has been created to handle it. Of course if there is a device capable of petrified all things in business that we run so we do not have to work hard, face to face directly not even need to wait for the arrival of clients or buyers in front of the store. Just waiting for a report of every transaction that occurs from the device we have designed to be able to do all that. No claim may also be the creation of artificial intelligence device that can detect or deal with any fraud committed by the client or buyer when the transaction occurs. That way, the threat of big losses also can be resolved without having to take action themselves.

Importance Database for Business Shoes


2010
11.18

One effort that is now being done by some people that is trade. For example, shoe trade business. If we are one of the people who are doing trade business of shoes that we sell shoes not only from one brand or one type of shoe, of course, there are a variety of forms, models, sizes, colors and of course from some type of brand if we do not produce their own shoes these shoes. In contrast, if we just sell shoes only from one brand of shoes, only the model or design, color and size that distinguish one shoe with the other shoe. However, all forms of business that we run shoes would require specific records to find out a lot of shoes that can be sold in one period, total revenue from sales of shoes, many shoes that are still unsold and others. Not to mention that if we open a special order for shoes online or by ordering directly to the store, then there will be additional records for each order shoes are not directly available in the store.

The process that occurs when the buyer directly to the store to buy shoes that are directly available in stores is the buyer comes to choosing shoes to purchase, at the time the buyer is a potential buyer, because it’s not clear she would buy one of the shoes or not, Prospective purchasers will be served by the clerk to help him make a choice. If the buyer has to choose shoes, buyers will make purchases at the cashier. Manually cashier will record the purchase on the paper bill by writing brand shoes, shoe color and size and price of shoes or to replace those things with the codes that have been determined by the owner of the shop. Bon will be printed several times with the help of carbon paper so that when the buyer has paid the shoes he bought and gave the check to the buyer the seller then the seller still has evidence of sales that occur as record of transactions that occur. For a while vouchers available at the seller will be written back to the kind of books to find out the number of shoes that have been sold so it can be accumulated with a shoe that still exist, thus there would be no shoe is sold or lost without any apparent reason. However, this requires high patience, since it requires a short time not to do recording all transactions that exist, especially if the store that we manage are not small. Not to mention a small paper receipt if not treasure it may be lost. This will complicate the transaction records.

Not much different from the transaction directly in the shop, shoe purchases by ordering online and also come to the store also require registration. Only every order that was ordered by buyer not always exist in the plant. It certainly requires a separate listing. In addition because there is no direct payment transactions also because not all orders can be fulfilled by the provider. Payment transactions can take place by way of providing cash advance, the remaining payments given upon goods ordered has arrived in the hands of the buyer or can be directly paid all of them when the goods arrive in the hands of the buyer. All that will be recorded on the books of its own by the seller. Bon will be out at the time the transaction was carried out in full prior to full payment buyers will get a temporary receipt, as proof of booking. Data recorded in full payment before the books separately in order. But usually the purchase by way of the message subjected to additional payments as the cost of postage and special orders.

From a little explanation of the process that occurs in the shoe trade business if everything is done manually would take a long time, and require employees who have the tenacity of recording everything in detail. In addition, any goods that can sell, check the rest of these articles should also be done manually as well. This is of course very inconvenient. Therefore, the role of the database is needed. The use of database technology in the business world is useful because it saves time and money with our computerized database that can store many information such as print, load, display of accurate data, facilitate data access, isolating the data for the standardizations , reducing redundancy data and inconsistencies. With a data base of all incoming and outgoing goods and transactions that occur can also directly access d. And a consideration factor for the business person in a large scale is that if not carefully constructed design that can cause loss of data is needed, the data are inconsistent, the update process is slow and others. This will cause losses in the event. The database can minimize the possibility of a missing data. Therefore, the database is essential.

Operating System


2010
10.18

Before discussing more about the operating system, first I will explain the meaning of the operating system itself. Every time we run an electronic device, especially computers, laptops and mobile phones maybe, we will not escape from the terms of the operating system. Operating system is system software that is responsible for organizing and managing the hardware and as a base operating system so that software applications can be run. This operating system is software that was first installed or put on computer memory, while other software applications that work under the operating system. Can be interpreted that without operating system other application software also does not run.

The operating system also serves as a liaison between the software with the hardware, so the hardware is outside the body of the operating system to function properly. In addition, the operating system also functions as a regulator of applications that run simultaneously so no need to wait for one application is completed in operation to run other applications.

Currently, many kinds of operating systems. Operating systems that include Linux, Windows, Free BSD, Symbian, Palm, Solaris, Mac OS and others. Here I will discuss some advantages and disadvantages of several operating systems and OS that I know what I thought was best.

Of the many operating systems are most widely used is Windows. In addition to its use are relatively easy, perhaps because many people use it so that we become more familiar with this operating system than on other operating systems. Windows itself still has some kind or type, including Windows 95, Windows 98 and Windows ME which is now rarely used because it is still limited in its operation and the many applications that do not support the use of the operating system. Windows 2000, Windows XP, Windows Server 2003, Windows Vista, and Windows 7 is released in 2009. Windows 7 has advantages with faster access as compared with the other Windows. However, there are some applications that are incompatible with Windows is probably because Windows is a relatively new still, so still why applications that do not support the use of this operating system. He said this is the completion of Windows Vista that has deficiencies in terms of speed because it looks too heavy.

In addition to Windows Operating System which I have mentioned there is still one of Windows that will be released around the year 2014, this Windows called Windows Orient. Not known exactly how this operating system will operate. But of course it will be increasingly sophisticated.

Besides Windows Linux is also a lot of fans, this Unix-like Operating System. Not like Windows, the operating system can be modified, used and distributed again according to what is desired because the Linux source code is free or open to anyone. Linux was introduced in 1991 by Linus Torvalds. This operating system also has advantages when compared with Microsoft Windows. Linux has high security and stability but it also has high compatibility.

Unlike Windows and Linux, Symbian is designed specifically for mobile equipment or mobile. Symbian itself is a proprietary operating system developed by Symbian Ltd. Symbian OS is the most widely used by Nokia in particular the series E and N series because this series requires a lot of similar applications on common operating systems. For example, Series E member facilities Quickoffice to open or create text like Microsoft Office, but certainly not as complete as Microsoft Office. But to run the application there must surely Operating System. Symbian can do multitasking and security like a desktop. But, of course, the Operating System is also susceptible to viruses, although not all viruses can infect due to limited operation.

After Windows, Linux and Symbian OS there are also Mac Os, which stands for Macintosh Operating System. Mac is an operating system developed by Apple Computer intended for use with Macintosh computers or also called the MacBook. Operating systems can not be run by an PC based IBM. The latest version of Mac OS is Mac OS X (Mac OS Ten), which was introduced in 2000. One disadvantage of this operating system is the price is expensive, but almost every Apple product is the price is high compared with other products. However, if we use this operating system, we can also run other operating systems. For example Windows XP, Windows Vista, even Linux can also be run easily by using Boot Camp on Mac Leopard. In addition, this operating system also has the advantage in the field of resolution pictures or graphics. So if we want to create or editing some pictures, it will be easier to use this operating system.

From some brief explanations about the OS that I know in my opinion it is best to windows, especially windows 7. Because in addition to the operation of the Windows OS that is fairly easily mastered also a fairly high speed. Boot and Shut Down faster process also looks attractive even 3D projections. In addition to these windows there are also several features that support and facilitate our access speeds in its use. By renewing the windows taskbar, it will be easier for us in more quickly access the program, besides the features of Jump In and windows search is also easier for us to find the file or our favorite song.

Windows 7 has been equipped with touch screen feature, so if we use these windows on a PC with touch screen then we did not bother to bring the mouse again. Another advantage is there in windows 7 is in the Community, the Windows Live Essentials then we can access data offline. In contrast to the previous windows, windows 7 has been using Internet Explorer 8, IE can detect the existence of sites that have a potential danger to a PC. Besides the features I have mentioned there are still other features such as Parental Control, Web Slices, Home groups, Snap, Shake, Peek and others.

Although Windows 7 has more advantages than any other OS, but there are also shortcomings. As I explained previously, Windows 7 can not operate some applications, besides that if in Windows Vista to recognize the hardware directly, in Windows 7 there is some hardware that can not be recognized directly. Indeed, the release of Windows 7 is a trial version, so many weaknesses should we understand. Still unknown is the final version of this Windows.

Software Licenses


2010
10.18

Software licenses are the laws that govern the use and distribution of software. In this case each piece of software that is licensed can not haphazardly traded within the community. There is a special permit that must be performed or fulfilled by every consumer who wants to use the software. For example, each license must be purchased at a price in accordance with the distribution company’s desired price. If the requirement is not met, and someone using a licensed software to several computers, then it can also be called a violation of the law of a software license. But not all software is licensed, the software can also be shaped freeware or shareware. In this article will discuss some of the licenses we often encounter when we buy or download the software on the Internet or anywhere else.

There are many kinds of software licenses, among others, Freeware or also called full version software. In accordance with the meaning Freeware can be downloaded for free on the Internet. But source code is usually on the freeware is not open source, so that we can not modify it. In addition, freeware is usually non-commercial use. But the advantage we can of freeware is that we can use the software anytime and anywhere because there is no time limit and amount of usage. Examples of freeware that is Firefox, Winamp and others. Perhaps that is the target license us, other than get it easier, we also do not need to purchase a serial number.

Proprietary software, software that is under the EULA. The software with this license is usually accompanied by requirements that determine the use of software, such as the number of installations or distribution. Examples of licenses for Microsoft Windows.

Adware. As with freeware, adware can also be obtained free of charge. But the difference there are ads on the software when we run, both at the beginning of the use or on the sidelines of its use.

In addition there are also shareware or trial or collectively, the demo software, and as the name suggests, too, shareware can be obtained free of charge but no time limit or number of the user to use it. That software can only be to try. There is usually during active use and how many times the use of the software. Having finished their active or trial period, we are required to purchase a full license of the software. Usually the password or serial number that is traded. We can use the software again when we already know or buy that serial number. Software that is included in shareware is winzip.

Trial ware is licensed with certain active period. Similarly, shareware, trial ware sometimes it’s just on some functions of the software is disabled. After the trial period is over, you are also required to purchase the full version of the software if you still want to use it.

In using shareware or trialware when the probation or trial period had expired license is usually the software can still be run again by re-instal it. But of course with the use or limitation of time and how many times we use the same as when we first install it. But this does not work on all existing trialware or shareware.

Unlike the above licenses, the Open Source license to open source code, so we can modify open source software in accordance with our wishes. In addition we can also distribute and publish the source code of our modified by any terms or independently according to the provisions proposed by the software company. Examples of open source applications is the Linux operating system, CMS Joomla, and so forth.

And finally there is the Demo Software. Demo software is intended only to demonstrate the features or the software version without a purpose is used for work.

Of the several kinds of licenses, license where we use the most? If we do not want to spend money to buy a full license for a software alternatives we should choose another alternative such as by downloading free ware over the Internet. Do not use pirated software because every license that is certainly already have a permit that if we break them we’ll get strict punishment if caught. Therefore, since now we have to get used to using legally licensed software without having to hijack it or choose another alternative to using a freeware of course with the system or the purpose of using the same software with the original software that we want.

3D Output on Cinema Development


2010
10.07

When this has been a lot of films that utilize technology to increase the output of 3D real sensation in the scene-the scene. But before I’ll explain what it is output. Output is something that indicates an outcome / output data that input from a process into one system so that the results of such processing can be understood or comprehended by human. This output will not be understood without tools or hardware of product/ output hardware. Output hardware may include a printer that can aimlessly hardcopy output in printed text or images, a monitor which can generate output in the form of impressions that have gone through processing, speakers that can produce output in the form of sound, and others. While the 3D output itself is the output that can produce a 3D effect or a real effect if we see a show or movie. And of course use the tool also to enjoy it.

Today the use of 3D output often found when we see the impressions in the movies, especially movies with 3D facilities, because not all the movies using this technology. One of the technologies that developed the technology is RealD 3D. The technology is already widely used by cinemas in various regions, especially in Indonesia itself. The technology is usually supported by a stereo projection system that can produces a rich picture or the view that as real. This technology uses a one digital projector as projection systems, in contrast to cinema in general that use multiple projectors to display images.
The release of this technology is the result of many film industry who have used the three-dimensional animation as movie effects, movie actors, and in the whole movie to give a better effect than in previous films.

This three-dimensional cinema can not we enjoy without any tools or hardware, eyeglasses. These glasses use color and light to create three-dimensional effect. Glasses are usually referred to as three-dimensional glasses are mostly used the lens mainly silver color as a means of regulating the light entering the eye. As with RealD technology, he uses circular polarization, with the Z-filter leading to a silver screen so the light caught can be changed on each eye shadow member is formed the impression that those impressions as if out of the cinema screen. The advantages of these glasses is that we can see which way we want without having to keep the view ahead and should not be tilted. In addition to using lenses or glasses silver mirror, there are also glasses that use the system to generate a wave of real view. Glasses are using the system changes the wavelength or LAMDA. The system can be found on 3D glasses digital camera. Besides that I mentioned, there are still many tools to display real impression like red blue glasses that several years ago used to watch a television show on a private television station in Indonesia.

Three-dimensional technology in the world of film industry in Indonesia is still very rare, especially in home theater at home. Besides the price is certainly very expensive, as well as devices that are not easily found. However, with the advance of technology development and the many movies that come with BluRay format,  then it will encourage the emergence of the device operation. And of course at an affordable price, too. Therefore, always support the development of technology for our lives will also be more prosperous.

storage media


2010

Each computer would have to have a media to store data or information. Computer storage media or computer memory is also called a reference to the computer device, computer storage media and the components inside the computer itself in the form of semiconductor-based storage media. Storage media is absolute is in every computer. Basically, the processing or the operation of the data, a computer needs processor or central processing unit to perform all calculations and control any other components. However, after going through data processing, data would need to be saved. Therefore, computer data storage is critical. The two components are the basis of a computer. In addition there is another component that functions as a supporting performance of the components contained in the computer so the computer can be operated.

In general, memory and storage of computer data, there are two types, namely the main memory or internal memory that is usually found in the body’s own computer and connected directly with the CPU and the secondary memory or external memory that can not be associated directly with the CPU.

1.       Primary Storage (Internal Memory)

As explained above, the primary storage or internal memory may be associated directly with the CPU. Both in reading the data to be processed and in terms of data storage. The internal memory is commonly known as Random Access Memory, or also called RAM. There are 2 sub-layers in the main storage, namely:

a.       Processor registers, located inside the processor.
This layer serves instruct the arithmetic and logic unit to perform various calculations or other

b.      Processor Cache
Is an intermediate stage between ultra-fast registers and main memory.

2.       Secondary Storage (External Memory)

External memory can not be associated directly with the CPU and requires a channel input / output in order to connect and transfer data from internal memory. External memory has several advantages, among others, the price is relatively cheaper, external memory will not lose data when devices are turned off, the capacity is usually larger, and can store data for longer. Examples of external memory or secondary storage:

a.       Hard disk drives

In modern computer hard disk included in the external memory using a USB or FireWire. This hard drive is a hardware component that stores the secondary data. This component contains magnetic discs to store data. Along with technological development, now the hard disk becomes thinner and smaller, but the accommodation is very big.

b.      Optical Storage

Included in optical st

orage such as CD ROM and DVD drives. Storage has access to longer if compared with disk drives.
CD ROM is read only (only can read, can not be written over and over again). To be able to read the contents of the CD ROM, the main component required is a CD Drive. In its development, CD ROM can now be written over and over again (Re Write / RW), better known as CD-RW.
In contrast to CD ROMs, DVDs have a much greater capacity is reached 8-9 GB whereas ordinary CD ROM only reached 700MB.

c.       Flash Memory

Flash memory is a chip that can be used to store data or erase existing data in it. Flash memory is commonly used in USB flash drives, memory cards, mobile phones, MP3 players and digital cameras.

d.      Magnetic tape

Magnetic tape storage media is the oldest. A magnetic tape cartridge can store up to 35TB of data without compression. Therefore, a magnetic tape data storage media which too expensive and rarely used.

e.      Floppy Disk

Floppy disk capacity is declining, that is for floppy disks 5.25 “capacity is 360 Kbytes (for DD) and 1.2 Mbytes (for HD). While the floppy disk 3.5 “capacity is 720 Kbytes (for DD) and for HD). Floppy disks can only save the text because of limitations in capacity. However, writing can be done repeatedly. Unlike the Zip drive, floppy device consists of a special floppy drives and cartridges, which can accommodate until nearly 100MB of data.

f.        Etc.

In addition to internal memory and external memory, there is still a tertiary memory. This memory usually involves a robotic mechanism and storage media that can be converted to storage media in accordance with the demands of the system, usually the data copied to external memory before being processed. Therefore, these storage media are rarely used and usually only used to archive information that is rarely used because of the tertiary memory data access is much slower when compared with secondary memory / external memory.

From the explanation which I have described above, in my opinion the best storage media and is suitable for a student that is flash or flash. Along with the advance of technology has many kinds of flash that is emerging. Various brands, sizes, shapes, and even a variety of prices from the cheapest to the most expensive there. But it is also not separated from the more sophisticated the product is removed.

Flash is a data storage device included in the NAND type flash memory using an integrated USB connector cable.

Although the capacity of flash memory capacity is not as big an external hard drive, but flash memory tends to be preferred. That is because the price of flash memory is more oblique, but depending on the brand, capacity and transfer speeds of flash memory, especially flash itself. The more popular brand, the greater the capacity, and the faster data transfer would be more expensive price. For example, SanDisk’s flash-Ducati that offers high transfer speeds, but the price can be up to 4 times the regular flash.

In addition there are several reasons why I think that the flash memory, especially flash is the most good. The reasons include:

1.       Easy to operate.

Excellence flash that can write and erase without the need for other tools is the main reason I chose this flash. When compared with the CD / DVD which still require a CD ROM / DVD RW for the storage of the flash is far more practical.

2.       Portability

The size and shape of the flash that a variety of flash can be an alternative selection. Flash is designed not only as a store of data, but also for comfort and ease of use. Small size and shape of diverse it will allow us to take him.

3.       The relatively fast transfer speeds

As I say above, various flash memory companies especially companies are now competing to offer the product with the facilities that better or the best on speed data transfer, not even half-training while also satisfying the read speed of 30MB / s and write speed of 25 Mb / s even more from it. For example, the flash A Data PD7, reading speed up to 33MB / s.

4.       Capacity large enough

Although when compared with an external hard drive flash still lost in terms of capacity, but this should not discourage fans of the flash. The capacity of the flash that started from 64 megabytes up to 512 gigabytes of data can accommodate a lot of what we need during the course. Not big enough. The amount of media capacity is dependent on flash memory technology used.

5.       The form is a variety

Unique form of flash-unique course the main attraction. We can choose the flash with a shape as we want. Even now there are also flash with a doll. Of course it will attract the girls to have them.

6.       Can facilitate data transfer from computer to computer

With good transfer rates and large capacity, flash can facilitate the transfer of data.

Although flash has banyk advantage, but the flash also has many weaknesses. These weaknesses include:

1.       Age short data storage

Age of data storage flash drive or flash is only about 5 years. When compared with the old hard drive storage can be up to 12 years or CD / DVDs that hold up to 15 years with proper storage processes and supported a high quality flash drive or flash would still miss.

2.       Susceptible to virus

Easy operation of the flash and can be directly related easily with all computer certainly this will be a soft target in the spread of the virus. In addition, the lack of virus protection on the flash to make the virus easily replicate itself into the flash and spread it to other computers.

The Impact of Information Technology


2010

information teknology

In this paper first I will explain what is information technology itself. Information technology is a form of human engineering to facilitate the delivery of any information from the giver to the recipient information by using the help of tools such as cellphones, computers, PDAs, television, etc., so the information can be received by the recipient.

Information technology has a lot of influence in the daily lives, for example in education, government, healthcare and others. But this influence is not entirely a positive influence. Many of them are also negative effects. But it all depends on us how to use it.

First I will explain what a positive impact of information technology. In the world of information technology education can help students in the process of tasks from teachers / lecturers. In addition, the materials no longer have to use books, materials can be accessed on the internet. Thus, we will be more efficient because it does not need much spending money to buy a textbook, our science is also increasing.

One type of information technology are now widely used by all circles of society that is the internet. Almost everyone uses the Internet. Whether for entertainment, find the money to seek acquaintance. Through the internet then our job becomes easier because almost all information can be accessed via the internet Internet is only a medium of communication that helps in the process of a task. Not to be copied and paste. So we should be able to use it in the positive. Do not let the title we will be revoked for committing plagiarism activities.

Information technology can also provide entertainment for us. For example, after a full day’s work of course we need the entertainment. One of the things we can do is play games online. Thus, the saturation of the lessons we will be lost. In addition to entertainment in terms of information technology can also strengthen kinship. Example, we all would have been familiar with social networking site facebook. Through our facebook can communicate with siblings, relatives, or friends who are far away from us directly as well connecting by facebook chat.

Therefore, I would like to thank the information technology that has helped me a lot.

If there is a positive influence there must be a negative influence. If we are addicted to information technology such as online gaming or chatting, then we can sit for hours in front of the screen. This is certainly a bad impact on our health. During that our bodies do not move and lack of exercise. We’re going to feel aches and pains. It is also my feeling. When I playing a game, I spent many time and forget what should I do in that time. In fact, sometimes I forget to do the work that should be done.

Besides that I mentioned above, there are many more positive and negative effects of information technology. But back to our own self how to use it.
