The purpose of buses is to reduce the number of "pathways" needed for communication between the components, by carrying out all communications over a single data channel. This is why the metaphor of a "data highway" is sometimes used.
If only two hardware components communicate over the line, it is called a hardware port (such as a serial port or parallel port).
Characteristics of a busA bus is characterised by the amount of information that can be transmitted at once. This amount, expressed in bits, corresponds to the number of physical lines over which data is sent simultaneously. A 32-wire ribbon cable can transmit 32 bits in parallel. The term "width" is used to refer to the number of bits that a bus can transmit at once.Additionally, the bus speed is also defined by its frequency (expressed in Hertz), the number of data packets sent or received per second. Each time that data is sent or received is called a cycle.
This way, it is possible to find the maximum transfer speed of the bus, the amount of data which it can transport per unit of time, by multiplying its width by its frequency. A bus with a width of 16 bits and a frequency of 133 MHz, therefore, has a transfer speed equal to: 16 * 133.106 = 2128*106 bit/s, or 2128*106/8 = 266*106 bytes/s or 266*106 /1000 = 266*103 KB/s or 259.7*103 /1000 = 266 MB/s
Bus subassemblyIn reality, each bus is generally constituted of 50 to 100 distinct physical lines, divided into three subassemblies:It is interesting to note that, in order to communicate, two buses must have the same width. The explains why RAM modules sometimes have to be installed in pairs (for example, early Pentium chips, whose processor buses were 64-bit, required two memory modules each 32 bits wide).

It means that either the "communications buss" or a connector has failed or the computer or some device on the buss has failed.
i dont know.. sorry
An infinite number. It would be AWFULLY slow.
No BUSS means lose of communication with computer, usually means you need to replace computer.
