    AT

    The AT stands for Advanced Technology. These motherboards were developed by IBM for their own computers. The motherboard is unable to cater to all needs of today’s advanced technology personal computers.

    The size of the motherboard is bigger than the ones that we have these days and takes a few inches more of space. The power connector on the AT motherboards has twelve pins.

    The AT motherboards do not have the sleep mode in which the essential parts of the motherboard while the power to others is suspended when the computer is not in use. Thus the power usage on the AT board is quite high. These were designed during a time when power consumption was not considered as a priority.

    The AT motherboards only offer one port for connection with peripheral devices. The port is for only a keyboard which makes it a difficult proposition in the current time to use it.

    The ATX also has the sleep mode which makes it a lot more energy efficient which is definitely a plus in current day and age. These were designed keeping in mind environmental considerations on saving power and performing using very limited power consumption.
