Final answer:
The central processing unit (CPU) is the circuitry in a computer that controls the manipulation of data.
Step-by-step explanation:
The circuitry in a computer that controls the manipulation of data is called the central processing unit (CPU). The CPU is often referred to as the brain of the computer because it performs the majority of the computational tasks. It takes instructions from memory, processes them, and produces the desired output.
