Q:

What units are used to measure CPU speed?

A:

Quick Answer

CPU speed is measured in megahertz and gigahertz. One gigahertz is 1,000 megahertz, so a CPU with a speed of 3.2 gigahertz is equivalent to 3,200 megahertz.

Full Answer

CPU speed is measured against the number of cycles per second it can perform. One hertz is equivalent to one cycle per second, and 1 megahertz is 1 million hertz. This means that 1 megahertz represents 1 million cycles per second. A CPU with a speed of 1 gigahertz can perform 1 thousand million cycles per second. The first microprocessors capable of performing at this speed were revealed to the public in the early 2000s. Moore’s law states that flagship CPU speeds double every 18 months.

  • Q:

    What is the purpose of a CPU?

    A:

    A computer's CPU is considered the "brain of the computer," being responsible for its major processes, like searching for information, sorting information, making calculations and advanced processes as well as decisions integral to the functioning of the computer. The acronym CPU actually stands for central processing unit and, as such, works behind virtually any task the user is doing on their computer, like writing essays, making photo albums or reading emails. The CPU is made out of a very complex silicon integrated circuit board mounted with tiny, microscopic transistors that can easily number in the billions.
