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

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.
