Q

ITX (Information Technology eXtended)

A

A form factor for motherboards that is much smaller
than ATX boards

34
Q

A

It is a type of CPU socket that stick out of the motherboard

35
Q

Lightning adaptor

A

One of the standard power, data and display connector types used in mobile devices

36
Q

Mb/s

A

megabit per second, which is a unit of data transfer rate

Southbridge

A

It maintains our IO or input/output controllers, like hard drives and USB devices that input and output data

65
Q

SSD

A

Solid State Drive. SSDs have non-moving parts, are a smaller form factor, and utilize non-volatile memory.

66
Q

Standoffs

A

Used to raise and attach your motherboard to the case

67
