Basic networking concepts

What is Networking?

A network consists of one or more systems that are connected to share resources.The networking computers shares information such as email, file, documents and resources such as printer, internet and disk storage.

There are Two common type of network include:-

1. Local Area Network (LAN)
2. Wide Area Network (WAN)

Local Area Network

A Local Area Network  is a network that is restricted to limited  area. Computers connected to a network are broadly differentiate as servers and  workstations. Servers are mostly not used by human beings directly, but rather run regularly to provide services to the other computers on the network. Service contribute can include printing and software hosting, file storage and sharing messages, data storage and retrieval .

Wide Area Network

Wide Area Networks connect networks in larger geographic areas. Dedicated different cabling and satellite up links may be used to connect this type of global network.. A WAN is complicated network . WAN uses multiplexers, routers and bridges to connect local and metropolitan networks for over all communications networks. However, a WAN will not appear to be much different than a LAN.To learn More about networking  you can go through CCNA Training in Chandigarh.

Requirement of Networking

Every network requires specialized hardware and software to make them work. Following are the essential components for network:

Client computers

The User devices that uses to access the shared resources. Usually they run desktop version of OS such as Window 10, Window 7, and Window XP. Client computers are also known as workstations.

Server computers

Computers that provide shared resources. Usually they run server version of operating system such as Window Server 8 or 2003, Linux and NetWare. Server computers run many functional services to control the shared resources.

Network interface card

Network interface card  is an interface that empowers the computer to communicate over the network. Every computer must have a network interface card in order to connect with the network. In previous time it was a separate card and need to be installed on motherboard. All modern computers have it as the essential part of motherboard.

Communication links

Communication links are physical media. Every computer network needs some sort of media to transmit the data.

Switches

When we have more than two computers in network, we cannot connect them directly. We need a mediator device that allows us to connect all computers together. Switches do this job happily. Each switch contains a certain number of ports. We can use an eight port switch to connect eight computers.

Routers

Router is an intermediate device that speaks all language of network. It makes communication between two different networks.

Benefits of Networking

Networking is all about sharing. Networking allows us to share three main things: information, resources and applications sharing .For More information go with CCNA Training in Chandigarh.

Information sharing

Networking makes it easy to share the information across the network. We can send or receive data files from other computers. We can communicate with each other in network via messaging application for example email service, chat service etc. We can store data in a centralized server for easy management.

Resources Sharing

Certain computer resources can be shared in the network such as hard disk, printer, scanner, modem etc. This allows us to track down the uses of resources. For example a network administrator can setup a printer server and share it in network. Then user can use printer server for printing. Now administrator needs only to monitor the print server instead of individual workstations.

Application Sharing

Application sharing is the most common in companies. Companies may have business application that needs to be update by several users. Sharing make it possible. It allows several users to work together on a single application.
