The control bus is a crucial component of a computer's architecture, responsible for transmitting control signals between the central processing unit (CPU) and other hardware components. These signals manage various operations, such as reading and writing data, coordinating the timing of processes, and ensuring that different parts of the system work together efficiently. In a typical computer system, the control bus operates alongside the data bus and address bus, forming the three main buses that facilitate communication. While the data bus carries actual data and the address bus specifies where the data should go, the control bus ensures that all actions are synchronized and executed correctly, maintaining the overall functionality of the system.
