6. History of Motherboard
 In 1980s such as the Apple II and IBM PC had published schematic diagrams and other documentation
which third-party replacement motherboards.
 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 .
 By the late 1990s, many personal computer motherboards included consumer grade audio, video,
storage, and networking functions without the need for any expansion cards at all.
 Laptop and notebook computers that were developed in the 1990s integrated the most common
peripherals.
 This even included motherboards with no upgradeable components, a trend that would continue as
smaller systems were introduced after the turn of the century.

7. FUNCTIONS OF MOTHERBOARD
• Motherboard provides the electrical connection between various components of the system.
• It provides an interface upon which other components of system such as CPU, RAM, ROM,
Chipset and expansion slots can reside.
• It provides the CPU interface with other peripheral support chips.
• It provides interface for various cards(Graphic Cards, NIC) to various expansion slots such as
ISA and PCI.
• It provides on-board IDE or SCSI interface for HDD, CD-ROM etc.
• It provides PS/2 interface for connecting keyboard and mouse.
