Cards in this deck (54)

  1. 1Molex connectora keyed connector used to connect to the power of an
    optical drive or a hard drive
  2. 2Berg connectora keyed connector used to the power of a floppy drive. A
    Berg connector is smaller than a Molex connector
  3. 320-pin or 24-pin slotted connectorused to connect to the power of the
    motherboard. The 24-pin slotted connector has two rows of 12-pins each,
    and the 20-pin slotted connector has two rows of 10-pins each
  4. 44-pin to 8-pin auxiliary power connectorhas two rows of two to four pins
    and supplies power to all areas of the motherboard. The 4-pin to 8-pin
    auxiliary power connector is the same shape as the main power connector,
    but smaller
  5. 5P8 and P9unkeyed connectors. They
    could be installed backwards, potentially damaging the motherboard or
    power supply. The installation required that the connectors were lined up
    with the black wires together in the middle
  6. 6MOBOMotherboard
  7. 7ATAdvanced Technology
  8. 8ATXAdvanced Technology Extended
  9. 9Mini-ATXSmaller footprint of ATX
  10. 10Micro-ATXSmaller footprint of ATX
  11. 11LPXLow-profile Extended
  12. 12NLXNew Low-profile Extended
  13. 13BTXBalanced Technology Extended
  14. 14CPUCentral Processing Unit
  15. 15RAMRandom Access Memory
  16. 16BIOSBasic Input/Output System
  17. 17ROMRead Only Memory
  18. 18PROMProgrammable Read Only Memory
  19. 19EEPROMElectrically Erasable Programmable
    Read Only Memory
  20. 20CMOSComplementary Metal Oxide Semiconductor
  21. 21NVRAMnon-volatile Random Access Memory
  22. 22ESCDExtended System Configuration Data
  23. 23POSTPower-On Self Test
  24. 24DIPdual in-line package (switch)
  25. 25FFFF0hlocation where the BIOS Boot Program in memory
  26. 26IDEIntegrated Drive Electronics
  27. 27EIDEEnhanced Integrated Drive Electronics
  28. 28ATAAdvanced Technology Attachment
  29. 29LPTline print terminal
  30. 30ZIFzero insertion force
  31. 31SEPSingle Edge Processor
  32. 32SECCSingle Edge Contact Cartridge
  33. 33SECC2Single Edge Contact Cartridge, version 2
  34. 34PPGAPlastic Pin Grid Array
  35. 35FC-PGAFlip Chip Pin Grid Array
  36. 36μPGAMicro Pin Grid Array
  37. 37LGALarge Grid Array
  38. 38Clock frequencymeasured in megahertz (MHz) or gigahertz (GHz)
  39. 39Clock speedDetermined by a crystal or oscillator located on the system board
  40. 40Wait stateA clock tick in which nothing happens. Used to slow down the CPU so
    the rest of system-board activity can keep up
  41. 41Derived System Clocksclock signals that are created from other signals using special
    circuits called frequency multipliers and frequency dividers
  42. 42FSBFront Side Bus
  43. 43Multiplierthe factor by which the front side bus (FSB)
    speed or frequency is multiplied to get the CPU clock speed
  44. 44Moore's Lawnumber of transistors per integrated circuit would double every 18 months
  45. 45PCProgram Counter:
    an internal memory location which
    contains the address of the next instruction to be executed. When the time comes for
    it to be executed, the Control Unit transfers the instruction from memory into its
    Instruction Register
  46. 46IRInstruction Register
  47. 47ALUarithmetic and logic unit (integers)
  48. 48SRStatus Register
  49. 49Control UnitThe control unit uses the information in the SR to execute conditional
    instructions such as "jump to address 7410 if the previous instruction overflowed"
  50. 50CoreThe heart of a modern CPU is the execution unit. The original Pentium had two
    parallel integer pipelines enabling it to read, interpret, execute and dispatch two
    instructions simultaneously
  51. 51Branch PredictorThe branch prediction unit tries to guess which sequence will be
    executed each time the program contains a conditional jump, so that the Prefetch and
    Decode Unit can get the instructions ready in advance
  52. 52Floating Point UnitThe third execution unit in a Pentium, where non-integer
    calculations are performed
  53. 53Level 1 CacheUsed by each CPU or core as temporary storage for instruction and data
    during the processing. Usually described as 2 values eg: 32KBx32KB
  54. 54Bus InterfaceThis brings a mixture of code and data into the CPU, separates the two
    ready for use, and then recombines them and sends them back out
