Most computer motherboards produced today are designed for IBM-compatible computers, which before long account for around 90% of global PC sales[citation needed]. A motherboard, like a backplane, provides the electrical connections by which the other brokers of the system communicate, but unlike a backplane, it also hosts the central treat unit, and other subsystems and devices.
Motherboards are also used in many an(prenominal) other electronics devices.
A typical desktop computer has its microprocessor, main computer storage, and other essential components on 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, although 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 microprocessors supporting chipset, which provides the supporting interfaces among the CPU and the confused buses and external components.
This chipset determines, to an extent, the features and capabilities of the motherboard.
Modern motherboards include, at a minimum:
* sockets (or slots) in which one or more microprocessors are installed[3]
* slots into which the systems main memory is installed (typically in the form of DIMM modules containing DRAM chips)
* a chipset which forms an interface between the CPUs front-side bus, main memory, and peripheral buses
* non-volatile memory chips (usually Flash ROM in modern motherboards) containing the systems firmware or BIOS
* a clock origin which produces the system clock signal...If you want to get a dear essay, order it on our website: Orderessay
