What is the Internet?

The Internet is a huge network of networks. It connects millions of computers together globally, forming a network in which any computer can communicate with any other computer as long as they are both connected to the Internet. Information that travels over the Internet does so via a variety of languages known as protocols. (Source: Webopedia)

What is the World Wide Web?

The World Wide Web, or simply Web, is a way of accessing information over the medium of the Internet. It is an information-sharing model that is built on top of the Internet. The Web uses the HTTP protocol, only one of the languages spoken over the Internet, to transmit data. Web services, which use HTTP to allow applications to communicate in order to exchange business logic, use the the Web to share information. The Web also utilizes browsers, such as Internet Explorer or Firefox, to access Web documents called Web pages that are linked to each other via hyperlinks. Web documents also contain graphics, sounds, text and video.

The Web is just one of the ways that information can be shared over the Internet. The Internet, not the Web, is also used for e-mail, which relies on SMTP, Usenet news groups, instant messaging and FTP. So the Web is just a portion of the Internet, although a large portion, but the two terms are not synonymous and should not be confused. (Source: Wikipedia)

Tips & Tricks

Bookmarking Sites

Internet browsers allow users to bookmark (save) favorite sites for easy access. This can be done with the Favorites icon (Internet Explorer) or the Bookmarks link (Firefox). These bookmarks are stored locally and are accessible from the computer you are using at the time the site is bookmarked.

File Types

Keeping Safe


In the field of computer security, phishing is the criminally fraudulent process of attempting to acquire sensitive information such as usernames, passwords and credit card details by masquerading as a trustworthy entity in an electronic communication. (Source: Wikipedia)

Search Engines

A web search engine is designed to search for information on the World Wide Web and FTP servers. The search results are usually presented in a list of results and are often called hits. The search results may consist of web pages, images, information and other types of files. Some search engines also mine data available in databases or open directories. Unlike Web directories, which are maintained by human editors, search engines operate by algorithms or are a mixture of algorithmic and human input. (Source: Wikipedia)
