Want this question answered?
NLX has slots parallel to the motherboard as ATX does not
NLX has expansion slots parallel to the board to allow smaller cases but may limit the number of expansion slots, rather than perpendicular like the ATX
Micro ATX is one of the offshoots of ATX. The main difference from the main ATX form factor is size. ATX is a rectangular board size that measures 305mm. by 244mm. Micro ATX is a square that retains the 244mm. width but cuts down the length to by 61mm.
my computer speed is very slow why?
For the most part it's size, and AT is very old computer wise. See here for more detail: http://www.devhardware.com/forums/motherboards-32/at-vs-atx-179846.html
Stop asking your homework questions from ist 150... I know who you are.
The three form factors for desktop system boards are: ATX, and BTX and NLX
ATX, MicroATX, Flex ATX, BTX, and NLX, In that order.
There are no similar form factors to ATX if you're talking about a slimline. Slimline form factors are NLX and LPX. The form factors to ATX are BTX, Micro-ATX, and Flex-ATX. There is no correlation between slimline and ATX.
it needs at least for gb of drives

These are form factors (size and shape) of motherboards you can plug CPUs into. They have no speed in themselves. For example, both ATX and micro-ATX (there is no mini-ATX) boards are available for most recent CPUs, making them the same speed with the same CPU.The differences between them are more along the lines of the size of the case it will fit in and how many expansion slots they have.BTX hardly exists anymore, it was a form factor proposed by Intel but cancelled in 2006.If you are in the market for buying one of them, I suggest going for one of the common standards: ATX (standard desktop tower size) or micro-ATX (a bit smaller)The two ATX standards are for all practical purposes the same except for the size and the number of expansion slots.See related link for more form factors.
