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:
A small plug/wire that can be connected among different points and an electronic circuit in order to alter an aspect of Hardware…
