Solution

The correct option is B Bus

A path by which communication is achieved between a central processor and other devices is called Bus.

The system bus is a pathway composed of cables and connectors used to carry data between a computer microprocessor and the main memory. The bus provides a communication path for the data and control signals moving between the major components of the computer system. The system bus works by combining the functions of the three main buses: namely, the data, address and control buses. Each of the three buses has its separate characteristics and responsibilities.

The control bus carries the control, timing and coordination signals to manage the various functions across the system.

The address bus is used to specify memory locations for the data being transferred.

The data bus, which is a bidirectional path, carries the actual data between the processor, the memory and the peripherals.

In computer architecture, a bus (a contraction of the Latin omnibus) is a communication system that transfers data between components inside a computer, or between computers. This expression covers all related hardware components (wire, optical fiber, etc.) and software, including communication protocols.
