Internet

Internet is the grand global system of interconnected computer networks that allows intercommunication and sharing large amounts of data and information.

Internet is built on top of protocols (such as IP, HTTP, SMTP, IRC, FTP). Access to internet is offered by internet service providers (ISPs).


World Wide Web

WWW (World Wide Web, or just web) is a network of interconnected documents on the internet - websites and webpages. Webpages are written in HTML (additionally, CSS) and refer to each other by hyperlinks (clickable links in text). The web itself works on top of the HTTP protocol which says how clients and servers communicate. Programs that let us browse this network are web browsers. The links to websites are URLs - Uniform Resource Locators.

HTTP

HTTP (Hypertext Transmit Protocol) is the protocol used for transfer of HTML documents between servers and the web.

Non-WWW internet services - email, torrent...


TCP/IP

Internet protocol (IP) establishes the rules for creating packets of data delivered over a network. Transmission control protocol (TCP) specifies connectivity of these packets. They are the most important parts of Internet protocol suite. Each computer that uses this protocol is assigned an IP address, sort of like a postal system - IP delivers packets to the destination IP address. IPv4 assigns a 32-bit number to the address, IPv6 a 128-bit number. Example IP address: 192.0.2.1
