{{main|Control unit}}
The '''control unit''' (CU) is a component of the CPU that directs the operation of the processor. It tells the computer's memory, arithmetic and logic unit and input and output devices how to respond to the instructions that have been sent to the processor.

It directs the operation of the other units by providing timing and control signals. Most computer resources are managed by the CU. It directs the flow of data between the CPU and the other devices. [[John von Neumann]] included the control unit as part of the [[von Neumann architecture]]. In modern computer designs, the control unit is typically an internal part of the CPU with its overall role and operation unchanged since its introduction.<ref>{{Cite web|date=2018-09-24|title=Introduction of Control Unit and its Design|url=https://www.geeksforgeeks.org/introduction-of-control-unit-and-its-design/|access-date=2021-01-12|website=GeeksforGeeks|language=en-US|archive-date=2021-01-15|archive-url=https://web.archive.org/web/20210115072904/https://www.geeksforgeeks.org/introduction-of-control-unit-and-its-design/|url-status=live}}</ref>
