  1. The Motherboard Computer Science I

  2. What is a motherboard? • The motherboard is a complex printed circuit board (CPB) that is the central component of most electronic systems, particularly computers.

  3. Alternately known as… • The mainboard • The system board • Logic board

  4. More about what the motherboard does… • The motherboard is an electrical platform that provides electrical connections through which the components of the computer communicate. • The motherboard contains a central processing unit, or CPU, also known as the brain of the computer.

  5. Motherboards can be found in: • Computer systems • Mobile devices • Clocks • Watches • Stop watches

  6. Motherboards also include: • Sockets for microprocessors • Slots where main memory (Random Access Memory) is installed • BIOS (Basic input/output system) • Expansion card slots

  7. History of the motherboard: • Before the invention of microprocessors, computers were made in mainframes, which were components that were connected by a backplane that had countless slots for connecting wires. • In old designs, wires were needed to connect card connector pins, but soon this would change when the CPU, memory and other peripherals were all placed on a printed circuit board. • During the late 1980s and 1990s, it was found that increasing the number of peripheral functions on the PCB was very economical. • By the late 1990s, they began to have full range of audio, video, storage and networking functions on them. Higher end systems for 3D gaming and graphic cards were also included later.

  8. Timeline of the motherboard: • 1975: Introduction of Apple I, a device that consisted a motherboard, a keyboard and a display. • 1987: Elitegroup Computer Systems was established in Taiwan and became the largest supplier of motherboards in the world. • 1989: AsusTek, one of Taiwan's top 5 company, started manufacturing graphic cards. • 1993: First International Computer Inc. becomes the largest motherboard manufacturer in the world. • 1997: Intel Corp. plans to add to its monopoly in microprocessor by manufacturing motherboards. • 2000: ATI Technologies Inc. announces graphic cards technology, an advancement, in computer graphics. • 2007: AsusTek becomes the world's largest maker of computer motherboards.
