C8) TCP/IP

Part 2: ANSWERS

A1) BIOS = Basic Input/Output System.

A2) CMOS = Complementary-Symmetry Metal Oxide Semiconductor.

A3) SIMM = Single Inline Memory Module: 30 or 72 pins memory.

A4) DIMM = Dual Inline Memory Module.

A5) UART = Universal Asynchronous Receiver Transmitter. A integrated circuit used to control the COMs ports.

A6) ECP = Enhanced Capacity Port: parallel port standard for PCs.

A7) IRQ 7

B1) ISA = Industry Standard Architecture.

B2) EISA = Extended Industry Standard Architecture.

B3) PCI = Peripheral Component Interface.

B4) AGP = Accelerated Graphics Port.

B5) IDE = Integrated Drive Electronics.

B6) EIDE = Enhanced Integrated Drive Electronics.

B7) ATA-2 = same as EIDE.

B8) SCSI = Small Computer System Interface.

B9) DLT = Digital Linear Tape.

C1) RAID = Redundant Array of Independent (or Inexpensive) Disks.

C2) RAID 0 = splits data across a number of drives while treating all of them as a single unit.

C3) RAID 1 = write identical data to two identical drives (mirroring).

C4) RAID3 = one parity drive and three or four data drives.

C5) RAID5 = distributes the parity information across all disks. It is an emprouvement of RAID 4.

C6) UNIX SHELLS = Cshell, the Bourne shell, and the Korn shell.

C7) CSMA/CD = Carrier Sense Multiple Access with Collision Detection.

C8) TCP/IP = Transmission Control Protocol over Internet Protocol.
