The motherboard form factor determines its physical size and shape. Larger form factors like ATX support more expansion slots but are more expensive, while smaller form factors have limited expansion but allow compact systems. Different form factors also require different case styles. Processor sockets house the CPU and connect it electrically to the motherboard, using various connection methods such as pin grid array or land grid array. Chipsets integrate multiple chips onto one, and earlier motherboards separated core functions between a north bridge and south bridge.

3.  The form factor determines the general
layout, size, and feature placement on a
motherboard.
 Different form factors usually require
different style cases.
 Differences between form factors can
include; physical size and shape,
mounting hole location, feature
placement, power supply connectors, and
others

5. Format Pros Cons
ATX
• A large number of
PCIe slots
• Supports multi-GPU
setups/several
expansions cards
• Large
• Tends to be more
expensive
Micro ATX
• Most balanced of the
three
• Might have too few PCIe
slots for some users’
needs
Mini ITX
• Compact
• Allows highly portable
PCs
• Limited RAM capacity
and only one PCIe slot
• Not every graphics card
will fit

6. • Flex ATX is an even smaller version of the MicroATX
• fewer PCI expansions
• fewer RAM slots
• Size 229*191

7. • This board is similar to the ATX motherboard in
terms of size and expansion slots
• The major difference with BTX boards are, they
are designed for better airflow

8. • These boards are generally made for lower-end
systems and will sometimes require use of a riser
card

9.  A socket for a personal computer is designed
to hold either an Intel processor or an AMD
processor.
 The processor socket (also called a CPU
socket) is the connector on the motherboard
that houses a CPU and forms the electrical
interface and contact with the CPU.

10.  Sockets and processors use different methods
to make the contacts between them.
 pin grid array (PGA)
 land grid array (LGA)
 fl ip-chip land grid array (FCLGA)
 staggered pin grid array (SPGA)
 ball grid array (BGA)

14.  Different chips integrated to a single chip
called the chipset.
 North bridge and South bridge was
introduced to the motherboard with PCI
slots.
 The south bridge controls the slower I/O
components like the Serial ports, USB ports
and the IDE.
