Computer System

Figure 1: computer system hardware / components

Salam~

Computer system can be divided into 2 components:
1) Hardware
2) Software

Hardware is any computer device or component that we can see and touch physically such as monitor, system unit, mouse, speaker, keyboard, printer, hard disk etc. However there are certain hardware that is not available physically, but can be used virtually. For example: Virtual Keyboard. (we will learn more about this in future topic. but you can find the information or picture from the Internet. just key-in the word in yahoo@google and search)

Hardware is very important because without them, the user cannot communicate with the computer. For example, without keyboard and mouse, user cannot access any document or software or even play games inside the computer.

Software is the opposite meaning of hardware. Software is the part of computer that we can see and use but we cannot touch it directly. If we want to use it, we must make sure that the software has been installed inside the computer. Install means the software has been loaded or put into the computer's system and ready to be used. For example, when you want to play a Shadowtale game, you must install the game into your computer first by using CD or thumb drive.

Software also called as application. It consists of certain programming languages or instructions that tell computer what to do. For example, instructions in Word application will tell the computer to receive data typed by the user including text, symbol or numbers.

Computer Evolution

Salam~~

Computer Evolution is one of the topic in ICTL subject for Form 1 students.
This topic describes about the history and timeline of computer innovations from the first invention until now.

The most interesting part in this topic is..you will see how computers becoming smaller from one generation to the next. From as big as the whole computer room until as tiny as a purse/wallet. What can we conclude from this topic is:

1. Computer innovations are growing rapidly that we can see many new things and inventions from time to time and we have to learn new lessons and technologies also each day.

2. Computers are becoming more cheap than the first time it was introduced. It has become more affordable. So there should be no reason why we cannot own at least one computer at home..remember the campaign "One Computer Per Home"?

3. We have to be more positive when facing the new technology and be ready to face the next phase of computer evolutions...technology will not wait for us..we are the one who needs to keep the pace~~
