Computer Network

A computer network is a set of computers connected together for the purpose of sharing resources. The most common resource shared today is connection to the Internet. Other shared resources can include a printer or a file server.

 A computer network is a system in which multiple computers are connected to each other to share information and resources.
Characteristics of a Computer Network:-
·        Share resources from one computer to another.
·        Create files and store them in one computer, access those files from the other computer(s) connected over the network.
·        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.
A computer network is a set of connected computers. Computers on a network are called nodes. The connection between computers can be done via cabling, most commonly the Ethernet cable, or wireless through radio waves. Connected computers can share resources, like access to the Internet, printers, file servers, and others. A network is a multipurpose connection, which allows a single computer to do more.
Following is the list of hardware's required to set up a computer network.
  • Network Cables
  • Distributors
  • Routers
  • Internal Network Cards
  • External Network Cards
Network and Computer Systems Administrators are responsible for the day-to-day operation of an organization's computer networks. They organize, install, and support an organization's computer systems, including: Local area networks (LANs) Wide area networks (WANs)

Introduction to Computer

COMPUTER- Basically the term COMPUTER is derived from "GREEK" word which means to calculate. Hence we can say that computer is a calculating device. In other word we can say that Computer is an electronic device which store data processing and give out the result. A computer is an electronic device which performs "Arithmetical and logical operation. A computer understood binary digit that is 0 and 1. Computer is an electronic device which accepts  data form user through input device and process the data with the help of processor after processing we desired output form. A computer also refereed as data processor because It can store the data, Process the data, and Retrieve data whenever desired.

Network Topology

Types of Network Connections Computer networks can be broken down historically into topology , which is a technique of connecting computers. The most common topology today is a collapsed ring. This is due to the success of a network protocol called the Ethernet. This protocol, or network language, supports the Internet, Local Area Networks, and Wide Area Networks. Star Topology A star topology is a design of a network where a central node extends a cable to each computer on the network. On a star network, computers are connected independently to the center of the network. If a cable is broken, the other computers can operate without problems. A star topology requires a lot of cabling. Bus Topology A bus topology is another type of design where a single cable connects all computers and the information intended for the last node on the network must run through each connected computer. If a cable is broken, all computers connected down the line cannot r...

Number system and its types:-

Number system :- This is the medium by which we can represent the number into equivalent of different format when we type some letter or word the computer translate them a number because computer can understood only number. Types of number system      Positional number system      Non positional number system   Positional Number System: In positional number system, there are only a few symbols called digits, and these symbols represent different values depending on the position they occupy in the number. The value of each digit in such a number is determined by three considerations__ 1.        The digit. 2.        The position of the digit in the number. 3.        The base of the number system. Non-Positional Number System:  In the non-positional number systems, the characters used are I for 1, II for 2, etc, and are of...
