CPU, which is often called just "processor", is an abbreviation for Central Processing Unit. That's the core of each and every laptop or computer or web server, since it performs each of the calculations and logical input/output operations. Though the performance of an Internet site or an application relies upon other things as well, like the amount of physical memory or the connection of the server, the pace at which a given processor runs determines how quick an app shall be executed. Later-generation processors have several cores which can drastically boost their overall power and efficiency, due to the fact that each core can take on a variety of processes individually or several cores can take care of 1 process which needs a significant computing power. Since each and every core works at a particular speed, this architecture can be looked at as several separate processors working together.
