Processor- is an electronic device designed to accept data, perform prescribed mathematical and logical operations at high speed, and display the results of these operations; the heart of the computer.
It is the computer's brain and it allows the processing of numeric data, and the execution of instructions stored in memory.
The Central Processing Unit's main responsibility is to carry out each instruction of the program in sequence. There are many different types of CPU's; older computers may still have the 486 CPU. Newer, and more advanced computers would have an Intel Pentium, Intel Celeron, or AMD Athlon chip. These CPU's come in different types and speeds, with the choice of an Intel Pentium III, a Pentium 4, a Celeron CPU, AMD Athlon XP, and Athlon CPU's.Central Processing Unit speeds vary from 1.6 GHz to 3.2 GHz.
The prices of a processor vary from $55.00 to $1100.00. An AMD Athlon with 2.8 GHz has the lowest price. An Intel Core with 3.33 GHz is the most expensive costing about $1100.00.
The importance of the Central Processing Unit can be compared to that of a heart in a human.
