CPU, which is sometimes called just "processor", is an abbreviation for Central Processing Unit. That is the core of each and every PC or server, due to the fact that it executes all of the calculations and logical input/output functions. Though the performance of a site or an app relies upon other things also, including the amount of physical memory or the connectivity of the server, the speed at which a specific processor runs determines how quickly a program shall be executed. Later-generation processors have a number of cores which can seriously boost their overall power and efficiency, due to the fact that each and every core can control numerous processes independently or several cores can control one process which requires a considerable computing power. As each and every core operates at a certain speed, this architecture can be looked at as numerous separate processors working together.
