EIDE

Enhanced integrated device (or drive) electronics. A second take on the PC platform's IDE drive interface that increases the previous maximum disk size from 504MB to more than 8GB, speeds up the data transfer rate to more than twice what IDE was capable of, and doubles the number of drives a PC can contain, bringing the number up to four. On the PC platform, EIDE gives SCSI-2 a run for its money, and while most people agree that SCSI-2 is technically superior, EIDE is cheaper to implement, which gained it widespread acceptance.

Puck

An input device, like a mouse. It has a magnifying glass with crosshairs on the front of it that allows the operator to position it precisely when tracing a drawing for use with CAD-CAM software.

Filters

Also known as rules, filters can be used to manage incoming and stored mail. Software that supports filters lets you create rules that perform actions, such as automatically routing messages to various folders based on the sender's address, sending prewritten replies to certain people, or deleting messages that include specific subject lines.
