  1. The World Wide Web An information system on the Internet, which allows documents to be connected to other documents by hypertext links, enabling the user to search for information by moving from one document to another.

A URL is the address of a specific Web site or file on the Internet. - The term web server can refer to either the hardware or the software that helps to deliver web content that can be accessed through the Internet. The most common use of web servers is to host websites, but there are other uses such as gaming, data storage or running enterprise applications.

  3. HTML HTML or HyperText Markup Language is the main markup language for creating web pages and other information that can be displayed in a web browser. HTML is written in the form of HTML elements consisting of tags enclosed in angle brackets (like <html>), within the web page content. HTML tags most commonly come in pairs like <h1> and </h1>, although some tags represent empty elements and so are unpaired, for example <img>. The first tag in a pair is the start tag, and the second tag is the end tag (they are also called opening tags and closing tags). In between these tags web designers can add text, further tags, comments and other types of text-based content.

  4. URL there are different domain types like .com is company .co is non US company .sch is school .gov is government .edu is university .ac is university ,museums and art galleries etc. .org is organisation .net is network .me is personal and there is different countries like .co.uk such as .au is Australia .dl is Germany .nz is New Zealand .fr is France .in is India .es is spain lets take http://www.bbc.co.uk/cbbc/cartoons for example: http means hyper text transfer protocol it might also have an s at the end, the s stands for secure e.g. Facebook will have https .www means world wide web .bbc.co.uk is the URL host name ..co.uk is the domain type ./cbbc is the URL path name.

  5. Browsers A web browser (commonly referred to as a browser) is a software application for retrieving, presenting and traversing information resources on the World Wide Web. An information resource is identified by a Uniform Resource Identifier (URI/URL) and may be a web page, image, video or other piece of content.[1] Hyperlinks present in resources enable users easily to navigate their browsers to related resources.

  6. Search Engines A web search engine is a software system that is designed to search for information on the World Wide Web. The search results are generally presented in a line of results often referred to as search engine results pages (SERPs). The information may be a specialist in web pages, images, information and other types of files. Some search engines also mine data available in databases or open directories.
