, Introduction to Computers:
Computer Systems:
Computers are electronic devices (switches, capacitors, and transistors, which are known as 0's and 1's or
on and off) that allow users to input data, process that data (the CPU), and store that processed data in
the computer memory.
A computer is a system with two main parts:
Hardware and software.
Hardware refers to tangible objects that can be touched and felt.
Software is a group of instructions that carry out specified tasks and enable hardware to function.
Computer Hardware:
The hardware component of the computer system consists of five parts:
Input devices,
Central processing unit (CPU)
Primary storage,
Output devices
Auxiliary storage devices.
Input device:
With the use of input devices, data or instructions are entered into the computer. .
Ex: keyboard, Mouse, Scanner.
Central processing unit (CPU):
CPU is a computer brain use to perform calculation and other operation.
Output device:
Output is what the computer produces as a result of data processing. After the input has been completed,
the output device plays or displays the outcome. Ex: Output devices include a monitor, printer, and
speaker.
Computer Memory:
Any physical component that can store data either momentarily or permanently is considered computer memory.
