Introduction of Motherboard:-
Motherboard is a
circuit board also called
main board. All components of a computer are connected together using motherboard. (It is called mother board because it connect all components together, like a mother). Components on a motherboard are connected together using a set of wires called
buses. All important components of computer (like processors, RAMs, Cards) are connected directly to motherboard while other components are connected using ports available on a motherboard. Computer motherboard has
Sockets,
Slots,
Bays and
Ports to connect different components.
Socket:-
A socket is usually a square shape connector. It connects chips in in it. Today Microprocessors are mostly in form of a chip and are inserted in Sockets.
Slots:-
Slots are usually rectangular connectors. There are many types of slots present on computer motherboard. slots are used to ad
extra features to motherboard. Slots are used to insert cards. Following slots are available on motherboards. Slots are also called
edge connectors.
RAM Slots
PCI Slots
AGP Slots
ISA Slots
EISA Slots
Bays:-
Bays are used to connect drives (CD-ROM, Floppy, Hard Disk, Tape etc.) to computer motherboard. Most commonly used bay is ATA (Advance Technology Attachments). It is available in PATA (Parallel Advance Technology Attachments) and SATA (Serial Advance Technology Attachments). Modern motherboards mostly coming with only SATA bays as it is faster then PATA.
Ports:-
Ports are mostly available on the back panel of Motherboard. These Ports are used to connect devices to computers. A variety of ports are available now a days.
PS2 ports are used to connect Keyboard and Mouse,
Serial Ports are used to connect many devices including mouse, joysticks etc.
LPT port is used to connect printers.
Sound ports are used to connect audio jacks.
VGA Port is used to connect monitor or LCD.
DVI port is also available for Monitor and LCDs.
HDMI port is avail able for Video interfaces.
The most widely used ports today are
USB Ports (Universal Serial Bus). almost each and every devices are available in USB connection. Thats why Modern motherboards come with very fewer slots. USB ports are HOT PLUG&Play Ports.
