CPU, which is oftentimes called just "processor", is an abbreviation for Central Processing Unit. That's the core of each personal computer or web server, due to the fact that it carries out all of the calculations and logical input/output procedures. Even though the performance of an Internet site or an application is determined by other things also, such as the amount of physical memory or the online connectivity of the hosting server, the pace at which a given processor works determines how soon a program will be executed. Later-generation processors have numerous cores which can severely boost their overall power and efficiency, as each and every core can take care of numerous processes separately or several cores can control a single process which requires a sizeable processing power. Due to the fact that every core runs at a particular speed, this architecture can be seen as numerous individual processors cooperating.
