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
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.)

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 high transfer rate of 1MB/s, it
also could be encrypted with pin code. With hopping rate of 1600 hops per second, it's difficult to be intercepted and are less
