What is the function of the CPU?
A CPU uses complex algorithms and programming to interpret signals and code. Many computer processors feature multiple cores, which help them process information more efficiently and quickly. A CPU retrieves information from the code within programs. It reads it to understand what the code is for, and then it executes the instructions.
A CPU is a small, square, internal piece of a computer that sits on the motherboard in a specialized slot made to hold a certain style or model of central processor. Many CPUs are connected to the motherboard with clamps and pins that are easily damaged. Since a CPU is the main component that processes data, it gets very hot as it works and needs a heatsink and fan to prevent damage, according to Fisher. Alternatively, some computers use water cooling systems.
The two most popular CPU brands are AMD and Intel, and these processors are found in a variety of electronics, including phones, laptops, desktops and gaming consoles. Processor speeds are measured in megahertz and gigahertz.

Clock
speed function
Every computer processor includes an oscillator
that operates at a certain number of pulses per second. These pulses set the
tempo for the processor; in most cases, a processor executes one or more
instructions per clock cycle. Clock speeds are usually measured in millions of
cycles per second (megahertz) or billions of cycles per second (gigahertz).
Average processor clock speeds have gone up quite a
bit over the past 10 years. As recently as 1990, a high-performance IBM 8088
processor ran at less than 5MHz. Today, processors from Intel and other vendors
routinely run well over 3GHz.
Clock speeds aren’t a good measure of computing power because there are
simply too many other variables. The design of the processor, the computer’s
system architecture, the system software, and even the amount of memory in a
computer all make a huge difference. By the time you take into account all of
the other factors that can affect a computer’s performance, the clock speed
doesn’t have nearly as much impact. In fact, I can imagine a lot of situations
in which a system with a 200MHz processor would beat the socks off a system
with a 600MHz or 700MHz processor.
