Computers connected to the network (Internet) are either servers or clients and communicate
with each other through networking protocol. The clients send requests to the servers and the
servers respond immediately with the required data.
The server stores the files and information in the form of websites. A website is a collection of web
pages. A web page is a document that contains text, graphics, videos, audios and links to other
pages. Every web page of a website has a unique address called Uniform Resource Locator (URL).
We can use this URL to access any web page from anywhere in the world. Have you ever wondered
how these web pages are created? HTML is the most widely used language to design web pages.
INTRODUCING HTML
HTML stands for Hypertext Markup Language. It is a markup language that describes the structure
of the web page. It allows us to create web pages that contain paragraphs, headings, links and
block quotes. The output of HTML web pages is the same on any type of computer and on any
operating system, i.e., Mac, Windows, etc.
Tech Tweak
HTML language was redesigned by Tim Berner Lee in 1989. It is a subset of Standard
Generalized Markup Language (SGML).

Some of the important features of HTML are:
It is a platform-independent language.
