INTRODUCTION TO NETWORKING tutorials

  • Before computer era, people had to use cumbersome paper writing and rewriting work. There after during computers without network, they had to use floppy diskette to share information

  • A network is a system that allows communication to occur between two or more devices. In computer networking the rules for communication must be well defined so that they can communicate without delay or any problem. If computers cannot understand each other then there will be NO INTERNET, NO SHARING OF FILES or SHARED PRINTING and then everything will stop.

 

Following are some of advantages of network

  • Networks are used to make work and communication more efficient.

  • When computers, printers, hard-disks, Cd & Dvd roms are connected together, people can pass and share data and information quickly.

  • Network helps to reduce TCO [Total Cost of Ownership] of equipment, in a way if a company owns 20 Pcs and all want to access PRINTER, DVD Rom then 20 printers or 20 DVD roms are not required. One can share 1 or 2 printer/or/DVD Rom with all the users.

  • It helps in centralized management of data

  • Security can be implemented and exact rights can be assigned to users, what each user can do and can not.

  • Network helps to maintain data backup.

  • Server Cluster and Data Replication possible only over network.

  • Large scale development in the field of Finance, Banking, Insurance, Tele Communication, Travel and BPO, KPO and IT industry is all possible due to network.

 

To build a network, you need three types of devices or components:

  • 1> Computers:- devices such as PCs and Servers running either Microsoft Windows, Macintosh OS, Unix (including Linux) or other operating systems—are responsible for providing applications to the users.

  • 2> Networking devices:- Such as hubs, bridges, switches, routers, firewalls, modems that are responsible for moving information between computers.

  • 3> Cabling :- such as copper or fiber cabling, is needed to connect the computers and networking devices so that information can be shared between components. Wireless communication also falls in this category.
