WGU C854 POWER FORM OPTIMIZATION
PROPOSAL ASSIGNMENT PAPER GUIDE
WITH COMPLETE SOLUTIONS
●● backside bus
Answer: Signal pathway between CPU and L2 or L3 cache
●● frontside bus
Answer: Where cache is placed if no backside bus exists
●● ATX
Answer: 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
●● micro ATX
Answer: Follows the ATX principle of component placement for
enhanced cooling but with a smaller footprint, fits into ATX cases
●● ITX
Answer: Family of small motherboard form factors with mini-, nano-,
pico-, and mobile- categories.
,●● Southbridge
Answer: This is in charge of anything other than CPU, memory and
cache, and PCIe
●● SODIMM and MicroDIMM
Answer: Form factors for laptop memory
●● L1 cache
Answer: Term for cache memory built into the processor
●● L2 cache
Answer: Term for cache memory external to the processor, possibly
physically close by
●● L3 cache
Answer: Term for cache memory on the motherboard, when the
processor already has external cache
●● firmware
Answer: The name given to any software that is encoded in hardware,
usually on ROM, and run without extra instructions from the operating
system
,●● option ROMs
Answer: Another term for things like the SCSI BIOS and video BIOS
●● Parity checking
Answer: A rudimentary memory error-checking scheme that offers no
error correction
●● 1
Answer: How many bits can ECC memory correct?
●● single-sided memory
Answer: Memory modules with chips on just one side
●● double-sided memory
Answer: Memory modules with chips on both sides, which the memory
controller must switch between
●● buffered or registered memory modules
Answer: These memory modules include specialized chips that act as
buffers for all signals from the memory controller, except, in some cases,
the data signals
●● Load-reduced DIMMs
, Answer: A form of registered DIMMs that increase performance by
maintaining parallel communication
●● onboard
Answer: Term for connectors included on the motherboard
●● off board
Answer: Term for connectors not on the motherboard, but residing on
adapter cards
●● drive interface
Answer: Name for the connector on the motherboard or adapter card that
connects via cable to the hard drive
●● 3m
Answer: Max cable length of USB 1
●● 5m
Answer: Max cable length of USB 2
●● 3m
Answer: Max cable length of USB 3
