Explains fundamental Networking and with different
types.
Answers
Answer:
A network is simply a group of two or more Personal Computers linked together. Many types of networks exist, but the most common types of networks are Local-Area Networks (LANs), and Wide-Area Networks (WANs). In a LAN, computers are connected together within a "local" area (for example, an office or home).
•Computer network
A computer network is a collection of computers and other hardware components interconnected
by communication channels (cables or satellites) that allow sharing of resources and information.
This session introduces you to the basic fundamental concepts of networking and Internet and
using different types of Internet connection.
Network are designed using following architecture
Peer-to-peer (P2P) Architecture:
Networks in which all computers have an equal status are called peer to peer networks.Generally in such a network each terminal has an equally competent CPU.
Client-Server Architecture:
Networks in which certain computers have special dedicated tasks, providing services to other
computers (in the network) are called client server networks. The computer(s) which provide
services are called servers and the ones that use these services are called clients.
Types of networks
There are two major types of network Local Area Network (LAN) and Wide Area Network
(WAN).
Local Area Network
A local area network (LAN) is one which connects computers and devices in a limited geographical
area such as home, school, computer laboratory, office building, or closely positioned group of
buildings.
Usually local area networks offer very high speeds and are used for connecting computers and
peripherals such as printers, scanners, etc.
Wide Area Network
A wide area network (WAN) is one which covers a broad area (i.e., any network that links across
metropolitan, regional, or national boundaries). The Internet is the most popular WAN, and is used
by businesses, governments, non-profit organizations, individual consumers, artists, entertainers,
and many others.
Internet
The Internet is a global system of interconnected computer networks that use the standard Internet
protocol suite to serve billions of users worldwide. It is a network of networks that consists of
millions of private, public, academic, business, and government networks.
Internet is one of the most useful technologies of modern times which help us in our daily, personal
and professional life. Internet is widely used by students, educational institutes; scientist and
professionals to gather information for research and general information. Businesses use the
Internet to access complex databases such as financial database. The Internet is the largest
encyclopaedia for all age groups. The Internet helps in maintaining contact with friends and
relatives who live across different locations via Internet chatting systems and email software.
Internet is also becoming a major source of entertainment for the general public.
World Wide Web
World Wide Web (abbreviated as WWW or W3, commonly known as the Web), is a system of
interlinked hypertext documents accessed via the Internet. With a web browser, one can view web
pages that may contain text, images, videos, and other multimedia, and navigate between them via hyperlinks
