Explanation of IT Terms

What is Internet Explorer?

Internet Explorer (IE) is a web browser developed by Microsoft and has been one of the most popular web browsers in the history of the internet. It was first released in 1995 alongside the Windows 95 operating system and became the default browser for Microsoft Windows.

Basic Concepts of Historical Web Browsers

To understand the significance of Internet Explorer in the context of historical web browsers, it’s essential to delve into some basic concepts.

1. Web Browser

A web browser is a software application that allows users to access, view, and interact with webpages displayed on the World Wide Web. It interprets HTML (Hypertext Markup Language) code, processes web content, and displays it visually.

2. Rendering Engine

A rendering engine is the core component of a web browser responsible for interpreting HTML and other web technologies to display webpages correctly. Different web browsers have distinct rendering engines, which can impact rendering speed, compatibility, and overall user experience.

3. HTML and Web Standards

HTML is the fundamental markup language used to structure content on the web. Web browsers adhere to web standards established by organizations like the World Wide Web Consortium (W3C) to ensure compatibility and consistency in the interpretation and display of web content.

4. JavaScript Engine

JavaScript is a programming language that enables interactive elements, dynamic functionality, and enhanced user experience on webpages. Web browsers incorporate JavaScript engines to process and execute JavaScript code swiftly.

5. Plugin Support

Historically, web browsers supported plugins, additional software components that extended browser functionality. Plugins allowed users to access multimedia content, such as videos or animations, and enable additional features not traditionally supported by the browser itself.

6. Security and Privacy

Web browsers play a crucial role in ensuring user security and privacy online. They implement security measures like encryption protocols, protection against malware and phishing, and options for managing user data and privacy settings.

Internet Explorer’s Impact and Legacy

Internet Explorer dominated the web browser market during the late 1990s and early 2000s, establishing itself as the primary browser for many internet users. Its integration with Microsoft’s Windows operating system and extensive user base contributed to its popularity.

However, as the internet landscape evolved, Internet Explorer faced criticism for its slow adoption of web standards, inconsistent rendering, security vulnerabilities, and lack of innovation. This led to a decline in its market share, ultimately prompting Microsoft to introduce a new web browser: Microsoft Edge.

While Internet Explorer may not be as widely used today, its historical significance in shaping web browsing cannot be overlooked.


Internet Explorer was once a dominant web browser that played a significant role in the development of web technologies and access to information on the internet. Understanding its basic concepts, as well as the broader concepts of web browsing, helps appreciate the progression of web browsers and their impact on the digital world.
