1. frontside bus: Signal pathway for communication between CPU and memory
2. backside bus: Signal pathway between CPU and L2 or L3 cache
3. frontside bus: Where cache is placed if no backside bus exists
4. ATX: Largest motherboard form factor, puts the processor and memory in line with the fan output of the power
supply, allowing the processor to run cooler
5. micro ATX: Follows the ATX principle of component placement for enhanced cooling but with a smaller footprint,
fits into ATX cases
6. ITX: Family of small motherboard form factors with mini-, nano-, pico-, and mobile- categories.
7. Southbridge: This is in charge of anything other than CPU, memory and cache, and PCIe
8. SODIMM and MicroDIMM: Form factors for laptop memory
9. L1 cache: Term for cache memory built into the processor
10. L2 cache: Term for cache memory external to the processor, possibly physically close by
11. L3 cache: Term for cache memory on the motherboard, when the processor already has external cache
12. firmware: The name given to any software that is encoded in hardware, usually on ROM, and run without extra
instructions from the operating system
13. option ROMs: Another term for things like the SCSI BIOS and video BIOS
14. Parity checking: A rudimentary memory error-checking scheme that offers no error correction
15. 1: How many bits can ECC memory correct?
16. single-sided memory: Memory modules with chips on just one side
17. double-sided memory: Memory modules with chips on both sides, which the memory controller must
switch between
18. buffered or registered memory modules: These memory modules include specialized chips
that act as buffers for all signals from the memory controller, except, in some cases, the data signals
19. Load-reduced DIMMs: A form of registered DIMMs that increase performance by maintaining parallel
communication
20. onboard: Term for connectors included on the motherboard
21. off board: Term for connectors not on the motherboard, but residing on adapter cards
22. drive interface: Name for the connector on the motherboard or adapter card that connects via cable to the
hard drive
23. 3m: Max cable length of USB 1
24. 5m: Max cable length of USB 2
25. 3m: Max cable length of USB 3

28. 4.5m: Max FireWire 400 cable length
29. 63: Maximum number of FireWire devices per bus
30. 72m: Maximum distance between FireWire devices
31. 15m: Max passive HDMI cable length
32. 30m: Max active HDMI cable length (hint: double passive HDMI length)
33. 3m: Max passive DisplayPort cable length
34. 33m: Max active DisplayPort cable length (11 times passive cable length)
35. 3m: Max Thunderbolt cable length
36. 6: How many levels deep can a Thunderbolt daisy chain extend?
37. green: Mouse PS/2 port color
38. purple: Keyboard PS/2 port color
39. IEEE 1284: Name of the standard for the parallel port
40. TN (Twisted nematic): Faster, less expensive LCD manufacturing method. Uses power to display black
pixels.
41. IPS (In-plane switching): LCD manufacturing method regarded as having best color representation at
all angles. Does not use power to display black pixels.
42. active matrix: LCD addressing technology using a transistor for each pixel. Crisp image but requires a lot of
power.
43. passive matrix: LCD addressing technology with a matrix of conductive traces instead of transistors for each
pixel. Muddy image but requires less power.
44. dual scan: LCD addressing technology that's a variant of passive matrix, splitting the display into halves that
are refreshed separately
45. 1024x768 256 colors: Final resolution and color count of Super VGA (8-bit color)
46. 800x600 16 colors: Initial resolution and color count of Super VGA (4-bit color)
47. XGA (eXtended Graphics Array): VGA successor capable of 256 colors at 1024x768 interlaced or
65,536 colors at 800x600 progressive
48. W: Letter used to indicate wide screen 16:10 video technology (e.g., WSXGA)
49. Q: Letter used to indicate width and height in a video technology were doubled, effectively quadrupling the count
