IIS (Internet Information Server) - This is the Microsoft web server program. A version called PWS (personal web server) is included with Windows 98.
Internet - The Internet is a global network of computers with roughly 500 million users, all over the world. Anyone can join this network. From your computer you can send and receive information anywhere in the world - all at the cost of a local phone call, 24 hours a day.

Intranet - An intranet is a 'private internet', not necessarily linked to the Internet itself, that can provide a powerful means of communication within a company or a group of trading partners. If it is linked to the larger Internet, it will be via secure 'firewalls' to protect your private information. An intranet can help a business, which has several different kinds of computer - Windows or DOS PCs, Macintosh computers, Unix workstations - which need to talk to one another.

If you have large files of data to transmit (such as video or high resolution photography) or you want to video and data conference regularly, you may want an ISDN line. Broadband connections are even faster than ISDN, and are beginning to supersede it).
ISP (Internet service provider) - A company that provides third party access to the Internet. All ISPs offer some standard basic services, such as 24-hour Internet access, a unique e-mail address for your company, storage space for your own website and basic software programs for browsing the Internet.
Java - An object-oriented programming language, developed by SUN, that has seen widespread adoption for use on the Internet.
