Introduction of Computer Systems

Computers (PCs) – Computer is an electronic

machines which take same data as input process that data according to given instruction and gives useful information and also store these information

It contains 1) Input Output Devices, 2) Processing Devices 3) Storage Devices 4) Communication Devices

Computers (PCs) – 1. Data – Data means row martial on which

actual processing is done( in the form of text & numbers)

2. Instruction – set of commands or set of statements or set of expressions – is nothing

but the program according to which data is processed.

3. Information –is the output or result given by computer.

Computers (PCs) –

Basics of Internet

Servers and Clients Communicate –

Basics of Internet

There are two types of computer networks:

Local Area Network (LAN): - A LAN is two or more connected computers sharing certain resources in a relatively small geographic location (the same building, for example).

Basics of Internet



Network Cable

Basics of Internet

Usually connected using Ethernet

http://en.wikipedia.org/wiki/Image:Ethernet_RJ45_connector_p1160054.jpghttp://en.wikipedia.org/wiki/Image:BNC_connector.jpg

Old: BNC connector for coaxial cable

New: RJ45 for twisted pair cable

Basics of Internet

To connect multiple segments of networks into a larger one

Hub◦A multiport repeater to enhance signal

within the same LAN Switch

◦Like hub but with intelligent◦Better performance

Router◦Forward packets from one LAN to another

Basics of Internet

Wide Area Network (WAN): - A WAN typically consists of 2 or more LANs.

The computers are farther apart and are linked by telephone lines, dedicated telephone lines, or radio waves.

Basics of Internet

The Internet is the largest Wide Area Network (WAN) in existence.
