RAM (Random Access Memory)
Computer memory used to temporarily hold programs and data.

Real Time
A real-time system or software is one specially designed to acquire, process, store and display large amounts of rapidly changing information almost instantaneously with microsecond responses as changes occur.

Replication
The process of making a copy of something. When using a groupware product, replication means copying a database from one server to another so that all users share the same information.

Repetitive Strain Injury (RSI)
Repetitive Strain Injuries occur from repeated physical movements doing damage to tendons, nerves, muscles, and other soft body tissues. The rise of computer use and flat, light-touch keyboards that permit high speed typing have resulted in an epidemic of injuries of the hands, arms, and shoulders. Use of pointing devices like mice and trackballs are as much a cause, if not more so. The thousands of repeated keystrokes and long periods of clutching and dragging with mice slowly accumulates damage to the body.

Router (networking)
This is an electronic link that enables two different local area networks to talk to each other, even though each network may be based on a different standard.
