and integrated drive controller and the computer's motherboard. Two drives (master and slave) are supported. The ATA
specification allows the drive to connect directly to the ISA bus on the computer. ATA transfer rate then had been developed to
133MHz/Sec and would come out with fastest rate later (please refer to
Serial ATA
).
DMA, data transfer rate is 16.6MHz/s.
Ultra DMA, data transfer rate is 16.6MHz x 2 = 33MB/s.
ATA/66, data transfer rate is 16.6MHz x 4 = 66MB/s.
ATA/100, data transfer rate is 16.6MHz x 6 = 100MB/s.
ATA/133, data transfer rate is 16.6MHz x 8 = 133MB/s.
(ATA/133 uses both rising edge and falling edge as ATA/66 but clock cycle time is reduced to 30ns.)

BIOS, is a set of assembly routine/program that reside in
EPROM
or Flash ROM. BIOS controls Input/output devices and other
hardware devices of motherboard. In general, to provide hardware independent portability, operation system and drivers is

Bluetooth is a wireless transferring technology that enables short-range wireless connections between desktop and laptop
computers, personal digital assistants (PDAs), cellular phones, printers, scanners, digital cameras and even home
appliances. The principle of Bluetooth (a chipset) is to transfer information and voices at the frequency of ISM Band. Every
Bluetooth technology devices do come with a standard address for you to connect one-to-one or one-to-seven (to form a
Pico-net), with transferring range up to 10 meters (100 meters to follow), using low power radio. Bluetooth do not only possess
