What is the role of the ALU in a CPU?

The ALU (Arithmetic Logic Unit) is responsible for performing arithmetic and logical operations within the CPU (Central Processing Unit). It performs basic arithmetic operations such as addition, subtraction, multiplication, and division, as well as logical operations such as AND, OR, and NOT. The ALU takes input from the CPU's registers and performs the requested operation, and then stores the result back into the registers. It plays a crucial role in executing instructions and manipulating data within the CPU.
