Internet glossary

Cookies

Cookies are little nuggets of information, given by the server to the user, to store session infor- mation between the times the user visits the same web site. When a user accepts cookies, the server is able to store and use information about the user’s actions on the visited web site. Although the cookies are used by the server, they are stored in the communicator.

Domain name and Host name

The terms “domain name” and “host name” are sometimes, slightly inaccurately, used synonymously. In a fully qualified domain name (e.g., www.forum.nokia.com), the first part of the name is the name of the host and the following parts are names of domains the host belongs to. Each host name corresponds to a certain IP address (see below). Host names are used because they are easier to re- member than IP addresses.

Hypertext Markup Language (HTML)

A language used to define WWW documents’

appearance and content.

Internet Protocol (IP) address

Multipurpose Internet Mail Extensions

A standard Internet format which permits in- cluding multiple mail objects in a single mes- sage. The mail objects can be, for example, formatted multifont text messages and non- textual elements, such as images and audio fragments.

Plug-in

Internet Access Point (IAP)

Internet Mail Access Protocol, version 4

(IMAP4)

A protocol used for accessing the remote

mailbox.

Proxy

In some networks, the connection between the WWW application and the resource you want to connect to is blocked by a firewall. The firewall protects the internal network from unauthorized external access. A proxy is an intermediary program which enables ac- cess through the firewall. A proxy can also serve as a network “cache,” which speeds up the downloading process.
