BEST COMPUTER INFORMATION ABOUT COMPUTER ARCHITECTURE, COMPUTER'S PARTS INFORMATION

"COMPUTER ARCHITECTURE"

Arrangements and connections of various components of computer system is called computer architecture.

"COMPONENTS OF COMPUTER ARCHITECTURE"

There are some basic components of computer architecture :
(1) Control Unit (CU)
(2) Arithmetic and Logical Unit (ALU)
(3) Main Memory
(4) I/O Unit
(5) Bus Interconnection

"CONTROL UNIT"

Its like a supervisor of  computer . CU control all activities of other parts of computer. CU allow other parts of computer to perform all activities correctly. CU reads instructions coming from main memory and decodes these instructions.

"ARITHMETIC AND LOGICAL UNIT (ALU)"

ALU perform arithmetic and logical operations. ALU perform logical operation such as compare two data items to find out which is greater then, equal to or smaller then. ALU also perform arithmetic operations such as addition, subtraction, multiplication and division.

"MAIN MEMORY"

It is also known as working area of computer and storage area of computer. It control instructions before execution and after execution.

"COMPUTER INPUT OUTPUT UNIT"

It handle I/O devices with peripheral devices. Its like a interface between I/O devices and CPU. To handle I/O devices I/O unit attached to the system bus.

"BUS INTERCONNECTION"

A physical pathway that is used to interconnection two different components of computer through wires is called bus interconnection.
