computer networking tutorial

Switches normally have numerous ports, facilitating a star topology for devices, and cascading additional switches. Any particular piece of equipment will frequently contain multiple building blocks and perform multiple functions.

It uses multiplexers, bridges, and routers to connect local and metropolitan networks to global communications networks like the Internet.

A node can be a computer, printer, or any other device capable of sending or receiving data from the other node through the network.

uses of computer network

It can be thought of as a multi-port bridge. Using a WAN, schools in Florida can communicate with places like Tokyo in a matter of seconds, without paying enormous phone bills.

Some of the configurations are designed to minimize the inconvenience of a broken cable; with other configurations, one broken cable can stop the entire network. Government agencies use MAN to connect to the citizens and private industries. Administrators, instructors, and even students and guests can be connected using the campus network. It can be used in an Airline Reservation. See the Topology , Cabling , and Hardware sections of this tutorial for more information on the configuration of a LAN. February A network is a group of two or more computers that are linked together. The internet is one of the biggest WAN in the world. It can also be used for communication in the military. Large campus networks can carry hefty price tags. It is a low range network. An employee of the organization can communicate with another employee through email, chat. Collaboration: Collaboration is one of the most important advantage of the intranet. With the advent of the tablet computer, and the touch screen devices such as iPad and iPhone, our definition of workstation is quickly evolving to include those devices, because of their ability to interact with the network and utilize network services.

Computer networks basics

Wireless access to a wired network is made possible by wireless access points WAPs. Dedicated transoceanic cabling or satellite uplinks may be used to connect this type of global network. For example, a group of servers might be located in a secure area, away from humans, and only accessed through the network. On the other hand, a workstation might not need as much storage or working memory, but might require an expensive display to accommodate the needs of its user. Many schools have installed a network, only to find that they did not budget for the necessary administrative support. See the Network topology diagrams in the Quick Reference section of Webopedia. A node can be a computer, printer, or any other device capable of sending or receiving data from the other node through the network. The school can provide network users with access to the internet, via an internet gateway. The signal is retransmitted at a higher power level, or to the other side of an obstruction, so that the signal can cover longer distances without degradation. A network must be connected with appropriate hardware. Offline Network: An offline network can be created inside the home, so it is also known as a home network. This network is made by using the telephone leased line provided by the telecom company. Servers Fail.

They were originally designed to transport circuit mode communications from a variety of different sources, primarily to support real-time, uncompressed, circuit-switched voice encoded in PCM Pulse-Code Modulation format.

It can also be used for communication in the military.

Application of computer network

For example, a school network might have high-speed high quality printers strategically located around a campus for instructor or student use. Bridges[ edit ] A network bridge connects and filters traffic between two network segments at the data link layer layer 2 of the OSI model to form a single network. In a protocol stack also see the OSI model , each protocol leverages the services of the protocol layer below it, until the lowest layer controls the hardware which sends information across the media. The high bandwidth increases the data transfer rate which in turn increases the productivity of our company.
