Very Short Question and Answers - Web Browser and Web URL

A web browser is a program that is used to visit different websites on the Internet by providing their address or URLs. It acts as an interface between a user and the World Wide Web.

Three popular web browsers are Google Chrome, Mozilla Firefox, and Microsoft Edge.

Hyperlinks allow users to navigate files, folders, and websites by clicking on highlighted words or graphics.

Modern web browsers offer features like downloads, bookmarks, password management, spell checking, search engine toolbars, tabbed browsing, and pop-up blocking.

A GUI-based browser is designed to render content such as pictures, audio, videos, animations, and text, and allows navigation by pointing and clicking with a mouse.

A text-based browser displays web content only in text mode, does not support multimedia content, and navigation is done using keyboard keys instead of a mouse.

Lynx is an example of a text-based browser.

Text-based browsers demand less bandwidth because they only display text and do not load images, videos, or animations, which require more resources.

URL stands for Uniform Resource Locator. It is a string of characters used to uniquely identify a resource on the Internet.

The four main elements of a URL are the scheme, host, domain, and path.

The scheme is 'https'.

The domain extension '.gov' is used for official government websites.

DNS associates a human-readable domain name with its unique IP address, similar to how a contacts app maps a person's name to their phone number.

The host is 'www'.

Domain extensions indicate the type of organisation or entity that owns the website; '.com' for commercial, '.org' for organisations, and '.edu' for educational institutions.

Domain names are easier to remember because they are words or phrases with a strong correlation to the website, while IP addresses are strings of numbers.

The path is 'india-glance/states-india'.

Domain extensions are regulated by the Internet Corporation for Assigned Names and Numbers (ICANN).

The domain extension for websites based in Japan is '.jp'.

'.in' for India and '.uk' for the United Kingdom.
