At the core of the computer is the central processing unit or CPU, the source of control that runs all programs and instructions. In order to function, computers use two types of memory: primary and secondary. The main storage is the primary memory, and data and programs are stored in secondary memory .
Which part of the computer stores and processes data?
Memory is the part of the computer that holds data and instructions for processing. Although closely associated with the central processing unit, memory is separate from it. Memory stores program instructions or data for only as long as the program they pertain to is in operation.
What processes a computer use data?
The processor, more formally known as the central processing unit (CPU) , has the electronic circuitry that manipulates input data into the information people want. The central processing unit executes computer instructions that are specified in the program.
What stores all data in a computer?
