Alja [10]

Answer:

World Wide Web (WWW):

The World Wide Web (WWW) or the Web, which was invented by Tim Berners-Lee in the year 1989, is an information system of internet servers containing web pages where specially formatted documents and resources, supported by Hypertext Transfer Protocol or HTTP, can be located by Uniform Resource Locators (URLs) with other hypertext links. Technical definition of the world wide web can be " all the user and resources using an HTTP protocol''.

Web-page:

A web page can be defined as the solitary page of a website. When a user wants to access a webpage, it can be accessed using a single URL, and that page can be copied and shared. Unlike a website, no navigation is required to view the webpage.

It may contain text, graphics, audio, video, downloadable hyperlinks for other pages, etc. Web browsers are used to display web page content on a computer or mobile by connecting to the server. Some of these documents have to use Flash or Java to view the information.

Downloading:

Downloading means receiving data from a remote system to a local system or initiating any such data transfer. There are some similar remote systems from which one can download. A download can mean the process of obtaining a file that has been submitted or downloaded for downloading, or any such type of file.

Website:

A website is a collection of interconnected web-pages, publicly available on the Internet, that share a domain name. Exchange of information can be done by the website. It can also be used to provide entertainment, news, and education.

A website is a means of obtaining information through the Internet. Special programs are used to view websites on computers, which are called web browsers.

Websites are found on the web-server. Every website has an Internet address which is called URL. The web-browser displays the website according to this address. The web-browser uses HTTP script (HTTP) to access them.

Web server:

A web server is a software that serves web pages, that is, software that transmits web pages to users. This can be divided into two parts: the machine on which the web-server is installed and the software that acts as a web server. These are the first hardware and the second software.
