1. Motherboard
A motherboard (sometimes alternatively known as
the mainboard, system board, baseboard, planar board
or logic board, or colloquially, a mobo) is the main
printed circuit board (PCB) found in general purpose
microcomputers and other expandable systems.
6. Expansion slot is a connection or port located inside a computer on
the motherboard or riser board that allows a computer hardware expansion card to
be connected.
Expansion Slots
7. Types of Expansion Slots
• Peripheral Component Interconnect (PCI)
Network card, SCSI, Sound card, Video card.
• Accelerated Graphics Port (AGP)
Video card.
• Peripheral Component Interconnect Extended( PCI-X)
• Peripheral Component Interconnect Express (PCI e)
Video card, Modem, Sound Card, Network Card.
• Communications and networking riser (CNR)
• Modem, Network card, Sound card.
8. Power Connectors
Power Connectors a special connector (the 20-pin block connector shown in
allows the motherboard to be connected to the power supply to receive
power.
10. Characteristics of Processors
• Hyper threading : This term refers to Intel’s Hyper-Threading Technology
(HTT). HTT is a form of simultaneous multithreading (SMT).
• Multicore: A processor that exhibits a multicore architecture has multiple
completely separate processor dies in the same package. The operating system
and applications see multiple processors in the same way that they see
multiple processors in separate sockets.
• Throttling : CPU throttling allows reducing the operating frequency of the CPU
during times of less demand or during battery operation.
• Speed : The speed of the processor is generally described in clock frequency
(MHz or GHz).
11. Important Memory Terms
• Parity checking
• Error-correcting code (ECC)
• Single- and double-sided memory
• Single-, dual-, and triple-channel memory
