Networking is a computer network of two or more devices connected together to exchange data. Moreover, computer networks can be made up of wires or they may be wireless.

Furthermore, networking is the core technology behind the Internet which has changed the world with easy access to information.

Basic Concepts of Computer Networking

So, below are some basic concepts of Computer Networks.

IP Address

IP stands for Internet Protocol. An IP address is a unique number assigned to a node on a network. Moreover, IP addresses are of four types, public, private, static, and dynamic.

Node

A node is a device that is part of a network. Moreover, nodes are capable of recognizing, processing, sending, and receiving data.

Network Packet

A packet is the basic unit of data in computer networking. Finally, data in a packet is grouped together and then transferred over the network.

Router

A router is a device that transfers data between two networks or sub-networks. Moreover, routers have two primary functions. Firstly, it manages traffic between networks. Secondly, it allows multiple devices to use the same internet connection.

Switch

A switch is a networking device that manages other devices or nodes in a network Also, switch transmits packets between different nodes in the same network.

Network Operating Systems (NTOS)

A network operating system is a system software that connects multiple devices or nodes on the network. Moreover, NTOS allows different nodes in a network to communicate with each other.

And below are some examples of network operating systems:

• Microsoft Windows Server
• UNIX
• Linux
• BSD
• NetWare

Main Advantages of Networking

Networking is an essential part of the modern-day internet. So, below are some advantages:

Data Sharing

Networking is used to share data and information easily. Hence devices on the same network are connected with each other so they are able to share data.

Resource Sharing

Networking enables two or more nodes to share the same resource. Further, network resources are usually of two types :

• Hardware Resource Sharing
• Software Resource Sharing

Communication

Computer networks enables different systems for fast and efficient communication. Moreover, communication can be of different forms including:

• Signals
• Data
• Text
• Audio
• Video

Data Decentralization

Networking is the technology that provided the base for data decentralization. Furthermore, data decentralization helps in securing and managing important data.

Network Performance

Also, we can calculate Network Performance on the basis of some parameters. Following is the list of some networking parameters:

• Bandwidth
• Network Delay
• Quality of Service
• Congestion in Network
• Network Resilience

Network Security

Generally, network security is very important keeping in view global Cyber Security Issues. Following are some aspects specific to network security.

• Network Surveillance
• End to end Encryption
• SSL
• TLS
