Universal Serial Bus (USB).
The Universal Serial Bus or USB controller is a set of specialized chips and
connections which acts as an interface between software and hardware. It can
work with three types of data transfers, and assigns bandwidth priorities in the
order of highest priority, Second highest priority, and when time permits priority for
Isochronous (real-time) transfer, interrupt transfer and bulk transfer of data
respectively.
12. Describe the IEEE 1394 (Firewire) bus.
The IEEE 1394 bus or the Firewire bus, is a serial bus interface standard for high-
speed communications and isochronous real-time data transfer, frequently used
by personal computers. It can connect up to 63 peripherals in a tree chain topology
and allows peer-to-peer device communications.
13. Create a table comparing the attributes of the standard serial bus, USB and
Firewire.
