| CPU is the core unit within a computer that performs most of the processing tasks, often referred to as the "brain" of the computer. It fetches, decodes, and executes instructions from programs and manages data in and out of the memory and other components. A CPU is one component of a computer's microprocessor but doesn’t necessarily refer to the entire chip. Figure 4246a shows the data transfer from CPU to DRAM memory in a computer.
