I IMAGEMAP In Web page development, an imagemap is a graphic image that is defined so a user can click on different areas of the image and be linked to different destinations. You make an imagemap by defining each of the sensitive areas in terms of their X and Y co-ordinates. With each set of co-ordinates, you specify a URL or Web address that will be linked to when the user clicks on that area. Imagemaps are used widely on many web sites as a more adventuresome form of main menu. INTERNET The word Internet (with a capital I) refers to the vast collection of networks all interconnected using the TCP/IP protocol. Should not be confused with an Intranet which is two or more networks connected together. INTELLIGENT AGENT A software routine that uses 'intelligence' to do an assigned task. For example, searching through the web for pages that match your personal tastes. INTRANET A (usually) private network, which is only accessible by authorised users. For example, a company could connect its Bristol, London and Birmingham offices with its own intranet. IRC Internet Relay Chat. A multi-user chat system. This is a feature of the Net, which allows you to hold 'live' text conversations with other people on the same channel. ISDN Integrated Services Digital Network. This is a digital alternative to current analogue phone lines. ISDN modems are already available, enabling its users to achieve much faster connection speeds. ISP Internet Service Provider. A company which sells connections to the Net. Compare with online service providers (OSP's) which provide an Internet connection in addition to their own exclusive members-only services such as chat forums, news services, and other assorted information |
