Explain motherboard in detail

A motherboard is the main printed circuit board in general-purpose computers 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 and memory, and provides connectors for other peripherals. Unlike a backplane, a motherboard usually contains significant sub-systems, such as the central processor, the chipset's input/output and memory controllers, interface connectors, and other components integrated for general use. It also makes arithmetical operations

Explanation:

Have a nice day ;]

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. The large PCB of a motherboard may include 6-14 layers of fiberglass, copper connecting traces and copper planes for power and signal isolation.

The motherboard contains the connectors for attaching additional boards, such as the CPU, BIOS, memory, mass storage interfaces, serial and parallel ports, expansion slots and all the controllers that are required to control standard peripheral devices such as the display screen, keyboard, and hard drive.

nope i prefer two because it is simpler, i don't like all the powers you get

explanation:

but that's my opinion

only #2 represents an object at rest on a table.

in #1, there is no normal force due to the table; the object is accelerating downward.

in #3, the vertical forces are not balanced; the object is accelerating downward.

in #4, neither the vertical nor the horizontal forces are balanced. the object is accelerating upwards and to the right.
