In this computer science lesson, you will learn about a very important register inside the central processing unit called the accumulator.

You will learn that a CPU register is a very fast, temporary storage area inside the CPU that can store one item, such as a value, a single program instruction or a memory address. As you will see, the accumulator is a register that stores the intermediate results of calculations while a program is running.

You will also learn about the role of some important CPU components, including the Control Unit and the Arithmetic and Logic Unit. You will see how these CPU components work together, along with the main memory, while a machine code program is being executed.
