What is the role of the data bus in a computer system?

The data bus in a computer system is responsible for transferring data between the different components of the system, such as the CPU, memory, and input/output devices. It acts as a communication pathway, allowing the transfer of data in both directions. The data bus carries the actual data being processed or stored, and its width determines the amount of data that can be transferred at a time.
