The Computer System
Some may think that data and information have the same meanings, but they don't. If we look at a number: 308910, one may think it is an I.D. Card number or a date or even a passport number. This is known as data because nobody knows what it is for sure. This is known as data. If the same number is shown like this: 30/89/10 than one recognises this as a date and it becomes information.
DATA+STRUCTURE=INFORMATION
A digital computer is a machine that can be programmed to accept data and process it into information. INPUT-PROCESS-OUTPUT.
Input is the process of entering data into the computer. The most common device used for inputting data is the keyboard. The mouse and the scanner are input devices too.
Once data is in your computer, it is processed by the processor. Output means getting processed data of your computer.
Soft copy means seeing your displayed data in your computer. While hardcopy means seeing your data on a paper copy.
What is the job of storage devices? Storage devices hold data permanently, so save it and retrieve it later.
Pheriphal devices are those things you attach to your computer system unit being an input device, output device or secondary storage devices.
There are many different types of computers:
Super Computers-are very powerful computers, which occupy special air-conditioned rooms. These computers are often used for research.
Mainframes-are fast, large capacity computers also occupying specially wiredand conditioned rooms. Mainframes are used by large companies- banks,airlines,universities etc.
Desktop Computers-are small enough to fit on top or along the side of a desk and yet are too big to carry around.
Pc- are a type of desktop computers. These are very easy to use.
Portable computers- These are specially designed computers which you can carry easily from one place to another.
Embedded computers- These are computers which many people don't notice. Everyone thinks that they are a machine and nothing else. But these type of machines are a computer too. Examples include: Washing machines, camera, hi-fi systems, telephones, microwave ovens, playstation, missiles etc.
Hardware are all those parts of the computer that can be seen and touched. Software is another word for programs. Application software is the kind of software that people use to make a document. System software is the software that the computer uses to manage its own internal activities and run applications.
A bus is a data roadway along which and commands travel. There are three types of bus:
-The Address Bus
-The Data Bus.
-The Control Bus.
