What do the data bus, address bus, and control bus collectively refer to in a computer system?

In a computer system, the data bus, address bus, and control bus are collectively referred to as CPU buses because they facilitate communication between the CPU and other components of the computer.

The data bus is responsible for transferring actual data between the processor, memory, and input/output devices. The address bus carries information about where the data is being sent or received from, indicating the location in memory or the specific I/O device. The control bus carries signals to manage and synchronize operations among the various components of the system, ensuring that data is transmitted at the right time and in a proper sequence.

Understanding the roles of these buses is fundamental as they directly affect the performance and efficiency of data processing within the computer system. The terms related to input/output interfaces, memory storage units, and power supply components describe different aspects of computer architecture and functionality but do not encompass the specific function of data, address, and control buses, which are integral to the CPU's operation and overall system communication.
