Answer 2

A central processing unit (CPU), or sometimes simply processor, is the component in a digital computer that interprets instructions and processes data contained in computer programs. CPUs provide the fundamental digital computer trait of programmability, and are one of the necessary components found in computers of any era, along with primary storage and input/output facilities. A CPU that is manufactured using integrated circuits is known as a microprocessor. Since the mid-1970s, single-chip microprocessors have almost totally replaced all other types of CPUs, and today the term "CPU" is usually applied to some type of microprocessor.

Answer 3

The CPU is the computer's control center. Think of it as the brain that does all the thinking (computation), thus it is called the Central Processing Unit.

Answer 5

CPU (Central Processing Unit) is the main chip installed on the motherboard of your computer. When a system is referred to as having an "Intel Pentium Processor" or "AMD Processor" it is this chip that it refers to. The CPU is made up millions of little transistors, acting as on/off switches constantly. Because of this constant on/off activity, CPU's get very hot, which is usually why they are covered with a large heatsink.
