PDF-Chapter The Memory Hierarchy To this point in our study of systems we have relied on

In our simple model the memory system is a linear array of bytes and the CP U can access each memory location in a constant amount of time While this is an effective model as f ar as it goes it does not re64258ect the way that modern systems really.

It also acts as an intermediary between the computer user and the computer hardware. What Is Central Processing Unit?. A Central Processing Unit is also called a processor, central processor, or microprocessor. It carries out all the important functions of a computer. It receives instructions from both the hardware and active software and produces output accordingly. It stores all important programs like operating systems and application software. CPU also helps Input and output devices to communicate with each other. Owing to these features of CPU, it is often referred to as the brain of the computer..
