SCSI (Small Computer System Interface) is a parrallel system bus.
No,you can drive a bus,but you can go into the bus.
The bus is used to carry signals from the CPU to and from RAM and the Hard drive. This is processed by the software. In essence the bus is the hardware interface and the software is the digital interface. Your BIOS (basic input output system) starts your PC and then hands over control to the operation system which then has the task to accept interrupt requests (IRQ's) from the hardware.

bus interface
A bus is just a collection of wires or a means to carry data. The term came from the old days when the main board only had traces and sockets, and no real components. The backplane resembled the "bus bars" in a telephone system. Now, a bus is generally traces on a motherboard or a type of interface. Serial here refers to data being sent end-wise, one bit at a time. If it were parallel, at least one byte would be sent at a time.
It stands for, "small computer system interface." Commonly referred to as "Scuzzy" It was (and is) the old school method and platform for connecting hardware to a computer. IE printers, Hard Drives, etc. Ironically it's transfer rates were and are faster. It is also known as "Daisey chain."----------------------------------------------------An SCSI interface is an adapter card used to connect SCSI devices to your computer. Similiar to a parallel port.-----------------------------------------------------------------------SCSI is an intelligent, peripheral, buffered, peer to peer interface. It hides the complexity of physical format.Every device attaches to the SCSI bus in a similar manner. Up to 8 or 16 devices can be attached to a single bus.
The bus interface unit is the part of the processor that interfaces with the rest of the PC. Its name comes from the fact that it deals with moving information over the processor data bus, the primary conduit for the transfer of information to and from the CPU. The bus interface unit is responsible for responding to all signals that go to the processor, and generating all signals that go from the processor to other parts of the system.

because serial bus moves in single way where parallel bus moves in different ways.
