A form factor is a specification of physical

dimensions, layouts, and other explicitinformation that helps ensure the hardware

works with products that support that form

factor

Computer form factors are related to othercomputer hardware.

But here we generally talking about

Motherboard Form factors, which are directly

related to the power supply and computercasing as well.

In computing, the form factor is thespecification of a motherboard - thedimensions, power supply type, location of mounting holes, number of ports on theback panel, etc…

Standard form factors ensure that parts are

interchangeable across different vendorsand generations of technology.(in enterprise computing, form factors ensure that server modules fitinto existing rackmount systems).

Most significant specification is for that of the motherboard, which generally dictates

the overall size of the computer case.Therefore Small form Factors have beendeveloped and implemented
