Motherboard
A motherboard is the central printed circuit board (PCB) in many modern computers and holds many of the crucial components of the system, while providing connectors for other peripherals.
The motherboard is sometimes alternatively known as the main board, system board, or, on Apple computers, the logic board.
It is also sometimes casually shortened to mobo.

Types of Motherboards
• This was the first type
of motherboard
•Size: 12 inches wide
and 11 inches long.
• problems: Access to
components and heat.
Full AT
•Size: 10 by 8.5 inches
•This motherboard is
meant for the classic
Pentium processors.
•The DIN keyboard
connector at
Baby AT
the top right corner of this motherboard makes recognizing
this motherboard a relatively simple task.
•Size: 12 by 7.5 inches.
•Bus speed: 100 MHz
The I/O ports and USB
ports meant for the
motherboard are
integrated directly into it.
•This board is mainly
meant for the Intel
processors
ATX (Advanced Technology Extended)
P4M266
Motherboard Interconnection
• Processor is the brain of our computer.
• Some key concepts
– Clock : In a computer, clock speed refers to how
fast the processor can process the data
– Cache: A small but fast memory area.
Levels of cache exists. (L1,L2,L3)
– Bus (FSB and BSB) : Collection of wires
connecting different Devices.
Processor
– Arithmetic Logic Unit (ALU) : internal part of the
processor which is used for all mathematical and logical
operations
– Floating Point Unit (FPU): also internal part of
processor, designed to handle any floating point
calculations
- Processor Architecture : 32 bit or 64 bit

Processor
Some Commercially available processors
• Pentium I-IV
• Celeron
• Athlon
• Duron
• Itanium (64 bit)
• Opteron (64 bit)
Processor
• RAM (Random Access Memory)
• Volatile memory
• Also called as primary memory
• Types of RAM
- Static RAM (SRAM)
- Dynamic RAM (DRAM)
RAM
• Static RAM
– Fast, has lower access time.
– Typical access times 5-25 ns.
– Expensive.
– Cache memory is Static RAM
RAM
• Dynamic RAM
– Slower, has higher access time than Static
RAM.
– Typical access times 60-120 ns.
– Much cheaper than SRAM.
– Main Memory is Dynamic RAM.
RAM
• SIMM (Single In-Line Memory Module)
-Smaller in length and capacity than DIMM
RAM
• DIMM (Dual In-Line Memory Module)
- Larger in length and capacity than SIMM
RAM
• Network Interface Card
Cards
• Sound Card
Cards
• Graphics Card
Cards
• Serial
– Serial port “serializes” data.
– Mouse, Modems etc use Serial port.
• Parallel
– Bits transmitted in parallel.
– Used primarily for Printers.
• PS/2
– Used to interface keyboards and pointing devices.
– Frees the serial port for other devices
Ports
USB
– Data transfer rate 12Mbps/480Mbps.
– Multiple devices supported on the bus(127).
– Hot pluggable, Plug-and-play.
– Provide power through the cable.
– Host based.
Ports
The slots and ports found on a motherboard include:
• Peripheral Component Interconnect (PCI)
- connections for video, sound and video capture cards,
as well as network cards
• Accelerated Graphics Port (AGP)
- dedicated port for video cards
• Integrated Drive Electronics (IDE)
- interfaces for the hard drives
•Communications and Networking Riser (CNR) slot
- insert CNR cards with Modem and Audio functionality.
Motherboard slots
• Universal Serial Bus
- external peripherals
• Memory slots
• PCI Express
- a newer protocol that acts more like a network
than a bus. It can eliminate the need for other
ports, including the AGP port
Motherboard slots
• What is it?
- Basic Input Output System
• Why is it necessary?
- boot up
• Important Functions- Display system setting.- Boot Sequence.- Drive Configuration.- Security.- Power Management.
