2. What is a Motherboard?
 A motherboard (sometimes
alternatively known as the
mainboard, system board,
baseboard, planar board or
logic board, or colloquially,
a mobo) is the main printed
circuit board (PCB) found in
general purpose
microcomputers and other
expandable systems.
• It holds and allows
communication
between many of the
crucial electronic
components of a
system, such as the
central processing unit
(CPU) and memory,
and provides
connectors for other
peripherals.

4. The Chipset
 A chipset is a group of microchips that are
designed to work with one or more related
functions that were first introduced in 1986 when
Chips and Technologies introduced the 82C206.
The original 82C206 chipset included the 82284
Clock Generator functions, 82288 Bus Controller,
8254 System Timer, dual 8259 Interrupt
Controllers, dual 8237 DMA controllers, and the
MC146818 Clock. Four of the 82C206 chips were later replaced
by CS8221 or NEAT (New Enhanced AT)
chipset that contained only three chips. This
was then replaced by the 82C836 SCAT
(Single Chip AT) chipset that combined all the
chips in the set into a single chip.
