Every computer consists of a microprocessor and memory. Without the two, the computer would not function. The microprocessor, commonly referred to as the Central Processing Unit (CPU), is the brain of the computer. Like the human brain, the CPU is responsible for managing the timing of each operation and carrying out the instructions or commands from an application or the operating system.
The CPU uses memory as a place to store or retrieve information. Memory comes in several forms, such as random access memory (RAM) and read-only memory (ROM). Memory provides a temporary location for storing information and contains more permanent system configuration information. This chapter provides an overview of these topics related to microprocessors and memory:
