Computer Diagram | Component of Computer | Computer parts

Those day computer are very useful for everyone. people are uses computer but many of them don't know, What are the basic components of computer, computer parts etc.. If you know the computer diagram then it will be very easy to understand the components of computer. So in this post you will see the basic computer diagram.

Those days computer are everywhere at Technology, Education, Business, Hospital, Research etc.. So it is mandatory that you have to know the "Computer Basic" In computer basic Computer Diagram is one of the most important topic. To know the Components of computer and the computer parts it is very important to the "Computer Diagram". 

Historically computer are mainly two types one is fixed program computer and another is stored program computer. The modern computers are based on a stored-program concept introduced by John Von Neumann. So computer diagram are also known as Von Neumann Architecture (Diagram).

 **Input Unit : Program or data is read into main memory from the input device. To perform task input is the raw element for any computer system.

In computer system there are many types of Input Unit is available Likes Keyboard, Mouse, Scanner, Touch Screen, OMR(Optical Mark Reader), OCR(Optical Character Reader), MICR(Magnetic Ink Character Reader), Barcode Reader, Light Pen, Microphone, Joystick and many more.

Input Unit

**Memory Unit : Mainly computer memory unit are divide into four parts - 

1. Primary Memory :  RAM and ROM are the primary memory . 
2. Secondary Memory : Magnetic Media(Hard Disk, Floppy Disk)  and  Optical Media(CD, DVD,Blue Ray Disk) are Secondary memory.
3. Cache Memory : Internal cache memory and External cache memory
4. Flash Memory : Pen Drive, Digital camera, IPOD  are the Flash memory.

Memory Units

**Processing Units : One of the most important parts of computer is processing unit or you can say CPU(Central Processing Unit). CPU is called 'The brain of Computer'. Processing Unit are divide into three parts -

1. Control Unit(CU) : All the task of computer control by CU. It is work like a bridge  between ALU  and Memory Units.

2. Arithmetic and Logic Units(ALU) : Accumulator is one of the most important parts of ALU. In the accumulator all logical operation will be done here likes AND, OR, NOT, NAND, NOR, XOR, XNOR.

3. Storage and Memory Units :  In the Processing unit small amount of  memory is present there, likes Register, Internal cache memory(level 1), Program counter etc..

Processing the Data

 **Output Units : After processing the data some results are evaluated by computer and it is stored in the computer storage device(memory), then with the help of output devices, we can present it to the user. 

Example of output device are Monitor, Printer, Plotter, Sound Box, Projector etc...

Output Units

**Buses : Data is transmitted from one part of a computer to another, connecting all major internal components to the CPU and memory, by the means of Buses.

Types of Bus :

1. Data Bus : It carries data among the memory unit, the I/O devices, and the processor.    
2. Address Bus : It carries the address of data (not the actual data) between memory and the processor.
3. Control Bus : It carries control commands from the CPU (and status signals from other devices) in order to control and coordinate all the activities within the computer.
