System Components common to most PCs - CORRECT ANSWER Motherboards

Motherboards - CORRECT ANSWER The spine of the computer
Known as: system board or mainboard
This is the printed circuit board (PCB)
Contains: Central Processing Unit (CPU), underlying circuitry, expansion slots,
video components, random access memory (RAM) slots, and a variety of other
chips
Are classified by their form factor (design), ATX, Micro ATX and ITX
ATX (Advanced Technology Extended) - CORRECT ANSWER Motherboard in the
mid-1990s to improve upon the classic AT-style motherboard architecture that had
ruled the PC world for many years. The processor and memory slots at right
angles to the expansion cards. This arrangement puts the processor and memory
in line with the fan output of the power supply, allowing the processor to run
cooler. 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.
ITX - CORRECT ANSWER The ITX line of motherboard form factors was
developed by VIA as a low-power, small form factor (SFF) board for specialty uses,
such as home-theater systems and embedded components. ITX itself is not an
actual form factor but a family of form factors. The family consists of the following
form factors:
Mini-ITX—6.7" × 6.7" (170mm × 170mm)
Nano-ITX—4.7" × 4.7" (120mm × 120mm)
Pico-ITX—3.9" × 2.8" (100mm × 72mm)
Mobile-ITX—2.4" × 2.4" (60mm × 60mm)
The mini-ITX motherboard has four mounting holes that line up with three or four
of the holes in the ATX and micro ATX form factors. In mini-ITX boards, the rear
interfaces are placed in the same location as those on the ATX motherboards.
These features make mini-ITX boards compatible with ATX chassis. This is where
the mounting compatibility ends because despite the PC compatibility of the
