Haag and Keen (1996) agreed that information technology is a set of tools that helps you work with information and perform task related to information processing. Included in this set are seven building blocks. All together, these building blocks are called an IT system (p.8). For an IT system we need: Input and output, software, communication devices, the processing engine, information, storage devices, and most important people (Haag & Keen, 1996).
According to Haag and Keen (1996) the definitions of the IT system is as follow,
1. Input and output devices that you use to enter information and commands and to receive (usually by hearing or seeing) the results of your requests. Input and output devices include a mouse, a keyboard, a screen, and a printer.
2. Software, or the set of instruction that are used to perform a particular task for you. Software includes word processing, budgeting, payroll, and communications.
3. Communication devices that connect IT systems and people all over the world. Communication devices include modem, satellites, and coaxial cable (similar to the cable you use to connect your TV to your VCR).
4. The processing engine contains two components: the central processing unit and the internal memory. The central processing unit executes the software to perform a particular task for you, while the internal memory is a temporary storage area for software and information.
5. Information you work with. Today, you can work with information in a variety of forms—text, sound, video, and even movement.
6. Storage devices that permanently store information and software. Storage devices include CD-ROM, tape, and disks.
7. Finally, and most important, people.
When most people think about IT, they think about the computer in front of them—a printer, a keyboard, disks for storing information, a screen, and perhaps a telephone modem for communicating. Although all are components of an IT system, you must look at yourself and other and realize that people are the most important building block. Without you, and IT system really is nothing more than computer—an expensive piece of electronic equipment that takes up space and gathers dust (p.9).
A Comparison on How Students Used Technology Before and Now
Computers were not yet an integral part of every classroom. According to Crane (2000), a study in 1995 indicated technologies in the elementary school were overwhelmingly used for basic skill exercise but were not connected to the ongoing curriculum. The same study noted that in middle and high school, computers, were being used primarily to create documents or to teach computer skill. Now in the 21st century, Charp (2003) reported that the use of technology for students has not only increased in the classroom, but also in homes, libraries, coffee shops and other places throughout our nation’s communities. During the years of President Clinton he pledged to wire all...
