Article Body:
Computer hardware is a physical part of a computer that executes within the hardware. It is unlike computer
software or data that can be frequently changed, modified or erased on a computer. Computer hardware is
not frequently changed and so is stored in hardware devices such as read only memory (ROM) where it is
not readily changed.
Most computer hardware is embedded and so is not visible to normal users. Below are the different types of
hardware’s found in a computer.
Motherboard: It is the central or primary circuit board making up a complex electronic system
such as a computer. A motherboard is also known as a main board, logic board or system board.
Central processing Unit: A CPU is the main component of a digital computer that interprets
instructions and process data in computer programs.
Random Access Memory: A RAM allows the stored data to be accessed in any order. RAM is
considered as the main memory of the computer where the working area is used for displaying and
manipulating data.
Basic Input Output System: BIOS prepares the software programs to load, execute and control the
computer.
Power Supply: Power Supply supplies electrical energy to an output load or group of loads.
Video Display Controller: It converts the logical representation of visual information into a signal
that can be used as input for a display medium.
Computer Bus: It is used to transfer data or power between computer components inside a
computer or between computers.
CD-ROM drive: It contains data accessible by a computer
Floppy disk: It is a data storage device
Zip Drive: It is a medium capacity removable disk storage system.
Hard Disk: It is a non-volatile data storage system that stores data on a magnetic surface layered
unto hard disk platters.
