Processing hardware

The purpose of processing hardware is retrieve, inter­pret and direct the execution of software instructions provided to the computer. The most common components of processing hardware are the Central Processing Unit and main memory.

The Central Processing Unit (CPU) is the brain of the computer. It reads and interprets software instructions and coordinates the processing activities that must take place. The design of the CPU affects the processing power and the speed of the computer, as well as the amount of main memory it can use effectively. With a well-designed CPU in your computer, you can perform highly sophisti­cated tasks in a very short time.

Memory is the system of component of the computer in which information is stored. There are two types of computer memory: RAM and ROM.

RAM (random access memory) is the volatile compu­ter memory, used for creating loading, and running pro­grams and for manipulating and temporarily storing data;

ROM (read only memory) is nonvolatile, nonmodifiable computer memory, used to hold programmed in­structions to the system.

The more memory you have in your computer, the more operations you can perform.
