World Wide Web

Before reading WWW, must read some basic computer networking terms:-

Computer Network

A computer network is a group or set of computers that share some resources. There must be at least two or more computers to form a network. In networking, computers can be divided into two types Client and Server.

A Client computer is an individual computer that uses services provided by servers upon request. Clients are connected to server/s via the network, they can request to server/s for providing data like a website, web page, or any other type of information.

The server computer is a particular computer assembled with high-quality components for providing high-level performance over the network. A Server computer operates 24x7 days for providing uninterpretable services. Any client across the globe can access data from the server. The server can be Web Server, Data Server, Proxy Server, etc.

Types of Computer Networks

1. LAN (Local Area Network)

2. MAN (Metropolitan Area Network)

3. WAN (Wide Area Network)


Internet Protocols

The set of rules and regulations is called protocols. In computer networking, every computer communicates with another computer over the network, so there is a need for some type of protocol for communication. The most used protocol is TCP/IP.

TCP stands for Transmission Control Protocol which is responsible for transmitting data.

IP stands for Internet Protocol, these protocols are responsible for maintaining the session between machines during data transmission.

World Wide Web

The World Wide Web is a system of Internet servers that support hypertext to access several Internet protocols on a single interface. The WWW was developed in 1989 by Tim Berners-Lee of the European Particle Physics Lab (CERN) in Switzerland
