Fundamental of Computer Science

Computer is an electronic machine that can perform specific task requiring of user.It can receive data from input devices then process and output the result with store data temporary and permanently.

Now , we are discuss about the Input,Output,Processing, Storage and Networking devices as given below:

1. Input device: The device can perform directly  input the data and instructions in a computer   is called input device .Such as:

• Mouse 
• Keyboard
• Microphone
• Joystick
• Track Ball
• Touch Screen
• Touch Pad
• Light Pen
• OCR
• MICR etc.

 2. Output device: The device can perform generate require result of user ,according by input instruction with output devices.Such as below:

• Monitor
• Speaker
• Printer
• Plotter etc.  

  3. Networking device: The device can used for communicate  the  devices within connected network.It will be globally access within networking devices.Generally LAN,MAN,and WANs are the types of network.Differences devices are used for network such as below:

• Modem
• HUB
• Switch
• Bridge
• Router

4. Processing device: The device can perform process the data in a few time .Mostly use  of as CPU.
