Hardware |
This is the name given to the physical parts of a computer. There are five general categories: |
|
|
The Central Processing Unit (CPU) |
It is the brain of a computer and controls how the rest of the computer works. It is assisted by the control unit (CU) and the arithmetic logic unit (ALU). The CU carries out instructions in the software and directs the flow of data through the computer. The ALU performs the calculations and logic operations. |
|
|
Input Devices |
They data into a computer. A mouse, a keyboard and a scanner are all input devices. |
|
|
Output Devices |
They get processed information out of a computer, for example to a printer, computer screen or even to speakers. |
|
|
Memory |
It enables a computer to temporarily store instructions and data. |
|
|
Storage Devices |
Thse include floppy disks, hard-disk drives, CD-ROM drives, DVD drives and tape drives. Some of these devices can read data whilst others, such as floppy disks, allow data to be saved as well as read. |
|
|
Peripheral Devices |
These are located outside the CPU but are controlled by it. That is, they can be added to a computer system. Input, output and storage devices may be peripheral devices. |
