What is motherboard?

Motherboard (M/B) is a primary circuit printed board (PCB) within a figurer that connect different business office of the computer. Influenza A virus subtype H5N1 motherboard (sometimes alternatively known every bit the mainboard, primary circuit board, organisation board, baseboard, planar board or logical board or colloquially, a mobo) is the primary printed circuit board (PCB) flora inwards full general role figurer as well as other expandable system.

MOTHERBOARD

It holds as well as allows communication betwixt many of the crucial electronic components of a system, such every bit the key processing unit of measurement (CPU) as well as memory, as well as provides connectors for other peripherals , as well as dissimilar a backplane at that spot connect all peripherals devices similar :- keyboard, mouse, printer, sound, video card, audio bill of fare etc. this board is referred to every bit the “mother” of all components attached to it. Often include peripherals, interface cards as well as daughtercards : audio card, video card, network card, difficult drives or other components.

Motherboard History:-

YEARS	EVENT
1981	First motherboard originally called a “planar” was used inwards the IBM personal computer.
1984	IBM was introduced the AT, or total AT motherboard cast factor.
1985	IBM innovate the Baby AT M/B cast factor.
1987	LPX motherboard cast factor was developed past times Western Digital.
1995	Intel released the start version of ATX specification for motherboard inwards July 1995.
1997	Intel, inwards a articulation endeavor amongst DEC as well as IBM developed the NLX cast factor inwards march
1997	Intel introduced start AGP back upwards motherboard inwards august as well as FIC inwards Nov 1997.
1997	Intel besides released micro ATX motherboard as well as specification inwards December.
1998	Intel released the WTX motherboard cast factor September.
1999	intel released Flex ATX motherboard cast factor.
2000	Kontron introduced the ETX motherboard inwards early on 2000.
2001	The UTX motherboard cast factor was introduced inwards 2001 past times TQ-components.
2001	Mini-ITX cast factor developed inwards Nov past times VIA technologies.
2003	The Nano-ITX cast factor released.
2003	The PCI Express criterion is introduced inwards 2003 past times PCI-SIG. motherboard amongst a PCI Express slot were released subsequently the same year.
2004	Intel released the BTX cast factor inwards Feb 2004. The micro BTX as well as Pico BTX besides released the same year.
2005	COM Express cast factor released inwards 2005
2005	XTX motherboard cast factor released.
2006	Supermicro released the SWTX motherboard cast factor inwards 2006.
2007	Pico – ITX cast factor motherboard developed inwards Apr 2007
2007	AMD developed the DTX cast factor inwards Jan as well as besides released mini-DTX cast factor inwards 2007.

· Motherboard Form Factor

1. AT (Advance Technology) :- These are the oldest type of motherboard used 286/386/486 processor. It has 2 ability connection each is half-dozen pins. Influenza A virus subtype H5N1 motherboard that follows the same blueprint as well as 12*13 cast factor that was inwards the master IBM PC/AT. It was superseded past times the Baby AT. AT motherboard figure below.

2. ATX (Advance Technology Extended) :- it is used inwards P2, P3, P4 motherboard. It has unmarried ability connection 20+4 pins or 24+4 pins. ATX is a specification used to outline motherboard configuration as well as dimensions to amend standardization. First released inwards July 1995 past times Intel, ATX has since had many revisions. The start was version 2.01 inwards June 2002, as well as 2.2 inwards February 2004. ATX motherboard figure below.

ATX FORM FACTOR

3. LPX (Low Profile Extended) :- it is developed past times Western Digital. It was blueprint alone for desktop computers widely used inwards the 1990. There was never whatever official LPX specification, but the blueprint commonly featured a 13*9 inwards (330*229mm) motherboard amongst the primary I/O ports mounted on the dorsum as well as a riser bill of fare inwards the centre of the motherboard, on which the PCI as well as ISA slot were mounted. Due to the lack of standardized specification, riser bill of fare was seldom compatible cast 1 motherboard blueprint to another, much less 1 manufacturer to another. The internal PSU connection was of the same type used inwards the AT cast factor. LPX motherboard figure below.

LPX FORM FACTOR

4. BTX(Balance Technology Extended) :- BTX is a cast factor for motherboard, originally intended to live the replacement for the aging ATX motherboard cast factor inwards belatedly 2004 as well as 2005. It was designed to alleviate simply about of the issues that arose from using newer technologies on motherboard compliant amongst the circa 1996 ATX specification. The ATX as well as BTX standards were both proposed past times Intel. BTX motherboard figure below.
