System Components common to most PCs - CORRECT ANSWER
Motherboards Processors
Memory
Cooling Systems
, Because those components are not in line with the expansion cards,
you can install full-length expansion cards-adapters that extend the full-
length of the inside of a standard computer case___ ATX (and its
derivatives) is the primary motherboard in use today. Standard ATX
motherboards measure 12" x
9.6"(305mm x 244mm)
Micro ATX - CORRECT ANSWER A form factor designed to work in
standard ATX cases, as well as its own smaller cases. Also referred to
as μATX. Follows the ATX principle of component placement for
enhanced cooling over pre-ATX designs but with a smaller footprint.
Some trade-offs come with this smaller form. For the compact use of
space, you must give up quantity; this is, quantity of memory slots,
motherboard headers, expansion slots, and integrated components.
You also have few micro ATX chassis bays, although the same small-
scale motherboard can fit into much larger cases if your original
peripherals are still a requirement. Are designed with power supplies of
lower wattage in order to help keep power consumption and heat
production down. Generally acceptable with the standard, reduced
micro ATX suite of components. As more off-board USB ports are
added and larger cases are used with additional in case peripherals, a
larger power supply might be required. Micro ATX motherboards share
their width, mounting hole pattern, and rear interface pattern with ATX
motherboards but are shallower and square, measuring 9.6" × 9.6"
(244mm × 244mm). They were designed to be able to fit into full-size
ATX cases.
