Here are most common top 20 Internet terms for beginners.

1) World wide web

World Wide Web is a subset of the Internet. It is referred to as the Web in short. All the documents and services you find on the Internet are part of the Web. So, when someone tells you they are surfing the Web they mean they are accessing the vast collection of documents and services on the World Wide Web.

These Documents on the Web are linked together using hypertext links, and the Hypertext Markup Language governs the way these documents will be displayed.

Some internet terms related to the World Wide Web are:

  • Webpage: A single page of information on the World Wide Web.
  • Website: It is a collection of Web pages.
  • Homepage: It is the first webpage when you open a website.
  • Hypertext links: These are the addresses in a webpage that will redirect you to another webpage.

2) Web browser

Web Browser acts as an interface to the World Wide Web. The vast collection of documents and services on the Web are displayed as web pages to the users by the Web Browser. Browsers primarily use the hypertext markup language programs to decide how the web pages appear to the users.

A user can have many Web Browsers installed on her/his device. There are many Web Browsers available the most popular ones are Internet Explorer for Windows, Google Chrome, Safari for IOS.


HTML known as Hypertext Markup Language is a programming language that is used to make sure that the browser displays the web pages in a specific format. The browser compiles the HTML code and then displays the webpage as the HTML program commands it.

The companies or organizations or individuals that create website use HTML to design their web pages.

4) URL (Uniform resource locator)

There are millions of web pages a browser can display to the user, but how does the user uniquely refer to a specific web page? The answer is using the URL. Every webpage has a unique URL. This URL is typed in the search bar of the browser to retrieve that webpage.

The URL has a syntax as follows.

URL syntax: protocol://domainOrIPAddress:port/path/filename

Let’s take an example to understand the syntax of the URL.

URL Example:

Here the protocol is https and the domain or the host name is Stemjar. Domain name or hostname usually ends with .com, .edu, .in, etc. depending on the type of the host. Intermittent-fasting refers to the path that takes you to the specific web page.


HTTP known as Hypertext Transfer Protocol is the set of standards or rules used to exchange data between the browser and the Web. HTTP is not a secure protocol. Ports on the system listening to the HTTP signal are usually left open.

HTTPS is known as Hyper Text Transfer Protocol over Secure Socket. Here the exchange of information between the browser and the web is administered over a secure layer. This protocol is used when the user accesses websites that are encrypted or sites that require a login.

6) IP (Internet Protocol) address

The Internet consists of an interconnection of many computers or nodes, each of these computers or nodes have an IP address assigned to them. IP address helps to identify a computer connected to the Internet uniquely. When we refer to a resource on the Internet like the website we use domain names.
