Lesson 5 - The Central Processing Unit
The Central Processing Unit is the part of the computer that performs the work. It carries out the core processing, logic control and calculation work on the electronic data.
The CPU also controls the transfer of information between the secondary and main memory (See Lesson 10 - Types of Memory). A CPU that is constructed on a single chip is called a microprocessor. The speed at which a CPU can process information is known as its clock speed.
This is measured in megahertz (MHz) or gigahertz (GHz). Mega refers to a million and hertz refers to frequency per second, therefore a 500 MHz processor would be capable of operating at 500 million cycles per second. Giga refers to a thousand million (billion), therefore a 2.4GHz processor would be capable of 2,400,000,000 cycles per second.
