章節(jié)摘錄

　　The term mainboard is applied to devices with a single board and no additional expansions or capability.In modern terms this would include embedded systems， and controlling boards in televisions， washing machines， etc. A motherboard specifically refers to a printed circuit with the capability to add/extend its performance/capabilities with the addition of "daughterboards".　　Most computer motherboards produced today are designed for IBM-compatible computers， which currently account for around 90% of global PC sales. A motherboard， like a backplane， provides the electrical connections by which the other components of the system communicate， but unlike a backplane， it also hosts the central processing unit， and other subsystems and devices.　　A typical desktop computer has its microprocessor， main memory， 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 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. 　　……
