Centronics
The Centronics Data Computer Corporation was the original creators of the parallel port. Because
of this many people still call the parallel port a Centronics port.

Client
A PC that requests information from a File Server.
CSMA/CA (Carrier Sense Multiple Access With Collision Avoidance)
In CSMA/CA each computer signals its intent to transmit before it actually transmits data. In this
way computers sense when a collision might occur and may avoid transmission collisions.
Broadcasting this intent however increases network traffic and so slows down network
performance. For this reason CSMA/CA is not as popular as CSMA/CD. Apple Macintosh
computers use CSMA/CA when connecting together with LocalTalk

CSMA/CD (Carrier Sense Multiple Access With Collision Detection)
The method whereby Ethernet and 802.3 stations transmit onto a network. The stations monitor the
network and if no activity is sensed, begin to transmit. They continue to monitor, and should multiple
stations have tried to access the cable at once, they’ll sense a collision, cease transmission, wait a
random time and then try again.

De-Spooling
The sequence where the print server removes (Polls) a print job from the print queue and forwards
the print job to the printer.

EPROM (Erasable Programmable Read Only Memory)
Pronounced “ee-prom”. A special type of ROM (Read Only Memory) that can be erased by high
intensity ultraviolet (UV) light and then rewritten, or reprogrammed. EPROM chips usually contain
UV-permeable quartz windows exposing some of the chips internal components.

Ethernet
A networking specification that first appeared in a modern form in the early 1980’s. It was
developed by Digital, Xerox and Intel. It describes the type of data frame that can be sent over a
network and the methods used to manage data collisions. It is similar, but not identical to the IEEE
802.3 specification.
