Question
Why is data bus bi-directional?
 Question Submitted By :: 86-Family
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
data bus is bi-directional bcoz
same bus is used for data transmission from microprocessor
to memory location or input/output device and vice versa.
thats y data bus is bi-directional

Answer
# 2
it is bidirectional since databus carry tthe information
both from memory to i/o device port and vice vera therfore
perform aa bidirectional operation of both input and
output..

Data bus will obviously be bi-directional, because whenever
we provide some input data for processing by the
microprocessor or microcontroller and any device, we are in
look out for output result which is again a data.

Answer
# 5
The bidirectional data bus, sometimes called the memory bus, handles the transfer of all data and instructions between functional areas of the computer. The bidirectional data bus can only transmit in one direction at a time.
Basically, the data bus is used to transfer instructions from memory to the CPU for execution. It carries data (operands) "to and from" the CPU and memory as required by instruction translation. The data bus is also used to transfer data between memory and the I/O section during input/output operations.
