Computer architecture

computer architecture:

It is the interconnection of hardware components to create computer that meet function,performance and manages all processing activities 

Computer Organization:

It is the well organized form of different component of computer 

Details:

Hardware Components:

Computer hardware includes the physical parts of a computer, such as the case, central processing unit (CPU), monitor, keyboard, computer data storage, graphics card, sound card, speakers and motherboard.

Input Unit

An input unit is a generalized term in computer science for any 'device' which can be attached to a computer system which can gather data from the real world so that it can be processed. For example - all of these are forms of input unit : Keyboard. Mouse. Touch pad.

Output Unit:

An output device is any piece of computer hardware equipment which converts information into human-readable form. It can be text, graphics, tactile, audio, and video. Some of the output devices are Visual Display Units (VDU) i.e. a Monitor, Printer, Graphic Output devices

Component of Processing Unit:

• Register
• Control Unit
• Arithmetical Logic Unit

Register:

Register memory is the smallest and fastest memory in a computer. It is not a part of the main memory and is located in the CPU in the form of registers, which are the smallest data holding elements.

Control Unit:

The control unit (CU) is a component of a computer's central processing unit (CPU) that directs the operation of the processor. It tells the computer's memory, arithmetic and logic unit and input and output devices how to respond to the instructions that have been sent to the processor.

Arithmetic logic unit:

the part of a computer that performs all arithmetic computations, such as addition and multiplication, and all comparison operations. The ALU is one component of the CPU(central processing unit)
