1. Aka audio modem riser.






2. Also called mirroring - this RAID array type provides fault tolerance because all the data is written identically to the two drives in the mirrored set.






3. Program code that provides a way for someone to gain access to a computer while bypassing security. Only a person who knows how the back door works can use it - but once in - that individual has the same access as the host program to all the internal

10. Aka paging file.






11. Aka musical instrument digital interface.






12. Aka Compact Disc-Read-Only Memory.






13. Software that runs on the computers in a network and that receives services from servers.






14. A connector that is slightly larger than an RJ-11 connector and contains eight wires. RJ-45 connectors most commonly attach twisted-pair cables to Ethernet network cards.

18. A type of motherboard and its variants most commonly used in recent PC systems.






19. An external serial bus standardized by the IEEE. Apple first developed it as FireWire. Other manufacturers call it i.link or Lynx. It can support up to 63 daisy-chained devices. Since the introduction of the faster update - IEEE 1394b - the original






20. On a circuit board - a small connector that slides down on a pair of pins jutting up from the board. Multiple pins are often side-by-side - and a jumper joins a pair of them.

25. Digital versatile disc (DVD) discs that can be written to once - but data cannot be overwritten. This term also refers to the drives that can write to these discs.






26. The traditional transmission system for television video signals - which combines the color and brightness information with the synchronization data into one signal. The TV circuitry then separates the two signals from the composite signal.
