Depends on your definition of bus.
USB ( Universal Serial Bus) serves both purposes...both output and input....when we copy something into a pen drive it serves as an output and when we view something from a pen drive it serves as an Input.
absolutely not , bus is just a data transfer media, we can't say it as input or output device
Data bus
Bus architecture is the pathway between the CPU and other peripherals. It is usually a shared input/output pathway. Bus is short for omnibus, which means, for all.
is an omr and input or output device?
both input r output
Input device.
The bus that determines the number of memory locations and Input/Output (I/O) elements that a microprocessor can address is the address bus. The width of the address bus, measured in bits, directly influences the maximum number of addresses the microprocessor can access, as it can address 2^n locations, where n is the number of bits in the address bus. For example, a 32-bit address bus can address 4 GB of memory.
it is an output device
output/input
output and input
Neither, it is not classified under input or output. It has its own identity
