A computer network spanned inside a tutirialspoint and operated under single administrative system is generally termed as Local Area Network LAN. Computer – Networking Advertisements. Motherboard has a computrr for internal network card where it is to be inserted.

Network cables are required to provide network access. Backbone of MAN is high-capacity and high-speed fiber optics. The communication delay is very low. Networking technology has revolutionized the world and created a new arena for the overall development of every nation.

What is a Computer Network

With the help of networking, it has now become very simple to share the expensive resources including storage space, processor, fax, etc. Computers and other devices are connected to a router using network cables. At huge level, internet works on Client-Server model. Metro Ethernet is a service which is provided by ISPs.

Before you start proceeding with this tutorial, I’m making an assumption that you are already aware about basic computer concepts like what is keyboard, mouse, monitor, input, output, primary memory and secondary memory etc. PAN may include wireless computer keyboard and mouse, Bluetooth enabled headphones, wireless printers and TV remotes.

LANs are composed of inexpensive networking and routing equipment. Connect a printer, scanner, or a fax machine to one computer within the network and let other computers of the network use the machines available over the network.

This may include Bluetooth enabled devices or infra-red enabled devices. The major purpose of such interconnectivity is to establish a communication system in order to make the work easier.

Ethernet is most widely employed LAN technology and uses Star topology, while Token-ring is rarely seen. Generally, networks are distinguished based on their geographical span. This tutorial has been prepared for the computer science graduates to help them understand the basic to advanced concepts related to Data Communication and Computer Networking. The resources such as printers, file servers, scanners, and internet are easily sharable among computers. The physical connection between networked computing devices is established using either cable media or wireless media.

It is the largest network in existence on this planet. It mostly operates on private IP addresses and does not involve heavy routing. It may contains local servers serving file storage and other locally shared applications. With the help of networking, the communication system has now become highly efficient, frugal, and fast. A computer can be connected to another one via a serial port but if we need to connect many computers to produce a network, this serial connection will not work.

A network can be as small as distance between your mobile phone and its Bluetooth headphone and as large as the internet itself, covering the whole geographical world. Create files and store them in one computer, access those files from the other computer s connected over the network.

PAN has connectivity range up to 10 meters. After completing this tutorial you will find yourself at a moderate level of expertise in Data Communication and Computer Networking from where you can take yourself to next levels.
