Motherboard is the main printed circuit board (PCB) in a
computer. The motherboard is a computer’s central communications backbone
connectivity point, through which all components and external peripherals
connect. However, all motherboards have a few things in common.The motherboard is a sheet of plastic that holds all the circuitry to
connect the various components of a computer system. Learn how the motherboard
functions to make all the other components work together.
The motherboard is a printed circuit that acts like the air traffic
controller of the computer. It coordinates all the processes, makes sure
power is routed properly, and connects all the other components of a
computer together. Common brands like Intel, MSI, Gigabyte, and Asus
manufacture motherboards for computers.
Phones, tablets and other small devices have motherboards
too but they're often called logic boards instead.
Their components are usually soldered directly onto the board to save space,
which means there aren't expansion slots for upgrades like you see in desktop
computers.
The IBM Personal Computer that was released in 1981, is
considered to be the very first computer motherboard (it was called a
"planar" at the time).
Note: A computer's motherboard is also known as the mainboard, mobo (abbreviation), MB (abbreviation), system board, baseboard
In laptops and tablets, and increasingly even in desktops, the
motherboard often incorporates the functions of the video card and sound
card. This helps keep these types of computers small in size. However,
it also prevents those built-in components from being upgraded.
Poor cooling mechanisms in place for the motherboard can damage the
hardware attached to it. This is why high performance devices like the
CPU and high-end video cards are usually cooled with heat sinks, and
integrated sensors are often used to detect the
temperature and communicate with the BIOS or operating system to regular the fan speed.
Devices connected to a motherboard often need device drivers manually installed in order to make them work with the operating system.
