5. Introduction…
A Motherboard (sometimes alternatively known as the Mainboard, system
board, planar board or logic board, or colloquially, a mobo) is the main
printed circuit board (PCB) found in computers and other expandable systems.
It holds many of the crucial electronic components of the system, such as the
central processing unit (CPU) and memory, and provides connectors for other
peripherals. Unlike a backplane, a motherboard contains significant sub-systems
such as the processor and other components.
Motherboard specifically refers to a PCB with expansion capability and as the
name suggests, this board is the "mother" of all components attached to it,
which often include sound cards, video cards, network cards, hard drives, or
other forms of persistent storage; TV tuner cards, cards providing extra USB
or FireWire slots and a variety of other custom components (the term
mainboard is applied to devices with a single board and no additional
expansions or capability, such as controlling boards in televisions, washing
machines and other embedded systems).

6. HISTORY…
Prior to the invention of the microprocessor, a digital computer
consisted of multiple printed circuit boards in a card-cage case with
components connected by a backplane, a set of interconnected socket.
In very old designs the wires were discrete connections between card
connector pins, but printed circuit boards soon became the standard
practice. The Central Processing Unit, memory and peripherals were
housed on individual printed circuit boards, which were plugged into
the back plate.
During the late 1980s and 1990s, it became economical to move an
increasing number of peripheral functions onto the motherboard. In
the late 1980s, personal computer motherboards began to include
single ICs (also called Super I/O chips) capable of supporting a set of
low-speed peripherals: keyboard, mouse, floppy disk drive, serial ports,
and parallel ports.

full range of audio, video, storage, and networking functions without
the need for any expansion cards at all; higher-end systems for 3D
gaming and computer graphics typically retained only the graphics
card as a separate component.
The most popular computers such as the Apple II and IBM PC had
published schematic diagrams and other documentation which
permitted rapid reverse-engineering and third-party replacement
motherboards. Usually intended for building new computers
compatible with the exemplars, many motherboards offered additional
performance or other features and were used to upgrade the
manufacturer's original equipment.

8. DESIGN…
A motherboard provides the electrical connections by which the other
components of the system communicate (talk with each other). Unlike
a backplane, it also contains the central processing unit and hosts
other subsystems and devices. A typical desktop computer has its
microprocessor, main memory, and other essential components
connected to the motherboard. Other components such as external
storage, controllers for video display and sound, and peripheral
devices may be attached to the motherboard as plug-in cards or via
cables, in modern computers it is increasingly common to integrate
some of these peripherals into the motherboard itself. An important
component of a motherboard is the microprocessor's supporting
chipset, which provides the supporting interfaces between the CPU
and the various buses and external components. This chipset
determines, to an extent, the features and capabilities of the
motherboard. 8
