stands for Central Processing Unit. In a computer, there is at least one CPU, which many have one more more processing Cores, which can often be considered to be CPUs themselves. The modern concept of CPU is usually a silicon chip that performs two basic tasks: its control unit fetches instructions from memory and executes them and the arithmetic logic unit (ALU) computes basic math and logic operations. The CPU is a critical component in a computer.
