HARDWARE COMPONENTS

PROCESSOR
The Central Processing Unit (CPU) is responsible for interpreting and executing most of the commands from the computer's hardware and software.
The CPU could be considered the "brains" of the computer

One of the most important things about CPUs is speed.

The speed of CPU is measured in Hz, i.e., number of operations can be done per second.

Because of the extremely high speed of CPU, computers can do millions of operations in a very short time.

Heat is released when CPUs run. High temperature, however, decrease the performance of CPU.

MEMORY
RAM/ROM

Random access memory is the working memory in a computer. Additional RAM allows a computer to work with more information at the same time which could have an effect on total system performance.

 ROM is read only memory it is valotile memory, it retains stored information even when the computer has been turned off. This is used for storing programs and data.
