Computer Networking
A computer network is a logical or physical interconnection between two or more computers such that they could communicate with each other. The process of transferring data between computers is known as data communication. The data and information can be transmitted over significant distances through the computer network.
Advantage of Computer Network
- The computers on the network can share hardware devices like printer, scanner etc.
- Data and software can be shared within the computer on the network.
- Files can be transferred from one computer to another computer.
- Computers in the network can communicate with each other.
Disadvantages of Computer Network
- Data and information may be stolen by computer hackers.
- If any computer in the network gets affected by the virus, there is a high chance of spreading a computer virus.
- Computers on the network have to depend on the server.
Device necessary for networking
Computer
All computers connected to a network that participate directly in network communication are classified as hosts. Hosts can send and receive messages on the network. In modern networks, computer hosts can act as a client, a server, or both. The software installed on the computer determines which role the computer plays.
Network Interface Card
It is a hardware device which contains electronic circuitry needed to ensure reliable communication between workstation and server.
Communication Media
Communication media is transmission media where data signals are transmitted. There are two main types of communication channels. They are: Guided or Bounded or Wired Communication Media and Unguided or unbounded communication media.
Connecting devices
Connecting devices such as hub, switch, bridge, repeater etc are necessary for networking-order to connect one computer to another computer.
Protocol
A protocol is a set of rules for communicating across the internet.
List of protocol
- HTTP (Hypertext Transfer Protocol)
- FTP (File Transfer Protocol)
- SMTP (Simple Mail Transfer Protocol)
