The Internet The Internet is a collection of computer networks around the world that are connected to each other via high-speed telecommunications links. These links may be made using optical fibre, copper wire or even microwaves (using satellites and microwave towers). Individuals connect to the Internet using a computer, modem, telephone line and Internet service provider (ISP). Uses of the Internet The Internet is used for communication and sharing files across vast distances. For many people it is the preferred method of sharing ideas and ®les because it is relatively cheap and fast. Some common uses of the Internet are: Chat, email, video conferencing, research, shopping, file sharing, news, self-publishing, technical support.

INTRANET
An intranet is a private version of the Internet. From about 1995, people started to adapt Internet and web-development tools to create corporate networks. Intranets use Internet standards and protocols to allow users in an organisation to communicate and collaborate more efficiently. With the appropriate permissions, employees can share information and collaborate with colleagues worldwide.
Intranets provide five core uses:
· email
· file sharing
· directories
· searches
· network management.
World Wide Web
The World Wide Web (WWW) is a graphic representation of the millions of documents and resources that are available on the Internet. When you think of the Internet and the WWW, think of them as two parts of the same object. The Internet is
the physical structure of millions of computers cabled together worldwide Ð the hardware, topology and technical part. The WWW is the content of the Internet Ð the graphics, text and hyperlinked structure. To access the WWW, you need:
· a web browser that allows you to view documents stored on the various servers that make up the Internet
· a computer that is connected to the Internet.
Browser software
In the early days of the Internet, the software used to access information on the Internet was text based and command driven. Users needed to know many
special commands to access the information held on the various servers. This changed quite dramatically in the late 1990s with the advent of the web browser.
Web browsers provide a graphical user interface (GUI) to the resources available on the Internet. The special commands are coded into web browsers, allowing users to interact visually with the vast resources stored on the Internet simply by using the mouse.
