Clickable Graphic  ::   An image or graphic with "active" areas to allow a user to click on it. An Image Map can have many different areas that are hyperlinks or "hot".

Client/server  ::   A front-end client and a back-end server allows multiple workstations (client) to access the same server at the same time over the LAN. The Internet is a global client/server network. The goal of such a design is to offload as much processing as possible to the desktop, leaving the shared information at the server.

More dangerous viruses can wipe out your computer and all your information. Some viruses can take over your machine and send spam from your computer. Without your knowledge, you can become a spammer.

The better traffic-analysis tools filter such visits out when creating traffic reports.

Cross Linking  ::   This is where the owner of two or more Web sites interlink the sites in order to boost their search engine rankings. If detected, cross linking often results in a search engine penalty.

Cryptography  ::   The process of protecting information by transforming it into an unreadable format. The information is encrypted using a Key, which makes the data unreadable, and is then decrypted later when the information needs to be used again. See also Public Key Cryptography and Private Key Cryptography.
