Basically computer system comprised by main units they are cental processing unit,control unit,arithmetic and logic unit and registers.
1. Input Unit
2. Central Processing Unit (CPU)
i. Control Unit
ii. Arithmetic Logic Unit (ALU)
iii. Registers,
3. Storage Unit, and
4. Output Unit
Input Unit
The user interacts with the computer via the input unit. The Input unit accepts data from the user and converts it into a form that is understandable by the computer. The input data can be characters, word, text, sound, images, document. The input is provided to the computer using input devices like keyboard, mouse, joystick, trackball, microphone, scanner.
Central Processing Unit (CPU)
CPU controls, coordmates and supervises the operations of the computer. It is also responsible for processing of the input data. CPU consists Arithmetic and Logic Unit (ALU) and Control Unit .CPU also has a set of registers for temporary storage of data, instructions address and intermediate results .
Storage Unit
There are two types of memory associated with storage unit. They are primary memory and secondary memory.
The primary memory Consists of RAM ( Random Access Memory) and ROM (Read Only memory) memories. Main memory stores the data, intermediate results and outputs etc..The input data that is to be processed is brought into the main memoty before processing. The instructions required for processing of data, any intermediate results are also stored in the main memory. The output is stored in main memory before being transferred to the output device.
Output Unit
The result generated after processing of data. The output may be in the form of text, sound, image. The computer may display the output on a monitor, sends output to the printer or plotter for printing, and also sends sound output to the speaker
