COMPONENTS OF COMPUTER

A computer consists of three main components

1. Input / Output Unit i/o
2. Central processing unit ( CPU )
3. Memory unit

INPUT / OUTPUT UNIT ( I/O )

• Information and the data is received and the processed data is sent to the external world through devices.
• Input devices collect the information and give it to the CPU.
• Output devices send out the processed results.
• Input / Output Devices of Computer

CENTRAL PROCESSING UNIT

• Transfers the instructions received to the registers.
• EXECUTES the instructions.
• Transfers the results to the output devices.
• Called as the THE BRAIN OF THE COMPUTER.
• Fabricated as the single integrated chip called microprocessor.
• performs arithmetic and logical operations.

PARTS OF CPU

• ARITHMETIC LOGIC UNIT - performs all types of arithmetic and logic operations on the data provided from the input devices.
• REGISTERS - Are temporary memory units for immediate processing of data.
• CONTROL UNIT - Coordinates with input and output units.

MEMORY UNIT

• Stores the data and instructions.
• Computer Memory Basics.

COMPUTER PARTS INTERCONNECTIONS

• connected through wires called as BUS.

MOTHERBOARD - Main circuit board of the computer.

INSTRUCTION CYCLE - 

• Sequence of events that occur in an instruction.
• FETCH--> DECODE--> EXECUTE-->STORE-->FETCH----->

MACHINE LANGUAGE - Under stood as Os and 1s.
