Computer System Board Tutorial

MOTHER BOARD:

Main printed circuit board of system, containing most of the components &

connections for expansion board etc. In any electronic device, it have two sides, 1 have BUS and other components, have two types Integrated(built in) and non integrated(plain)...

Following are the components of a Mother Board...

1) EXPANSION SLOT:

2) CMOS CELL:

3) BIOS CHIP:

4) SLOTS:

5) PERIPHERAL PORTS:

6) GRAPHICS ARRAY:

7) JUMPER

EXPANSION SLOT:

A socket is a component designed to hold an expansion card and connect it to system bus...e.g, ISA(16 bit), EISA(), PCI(32 bit), AGP(64 bit)...

CMOS CELL:

(Complementary Metal Oxid Semiconducter)

A semiconducter device that consist of two metal oxid semiconducter Field Effect Transistor(MOSFET)... One is N-type and the other is P-type, integrated on a single silicon chip...

BIOS CHIP:

A set of essential software routines that test the hardware at start up, start the operating system and support the transfer of data among hardware devices...

SLOTS:

Processor Slot (ZIF socket & slot 1 socket)

Memory Bank

Power Connector, Disk Cnector...

PERIPHERAL PORTS:

[ SERIAL PORT:

An i/o location(channel) that sends & receive data to & from comp's Cpu or a comunication device in sterps 1 bit at a time... e.g. PS2, COM1, 2, 3, 4, bit by bit Transmission have generally 9 pins...

[ PARALLEL PORT:

Byte by byte Transmission...

[ USB:

12 Mb/s, can connect up to 127 peripheral...

[ RJ:

Telephone & Modem(RJ 14), LAN(RJ 45 usually larger)...

GRAPHICS ARRAY:

CGA color graphic array

EGA enhanced graphic array

VGA visual graphic array

SVGA super visual graphic array

JUMPER:
