CPU, which is sometimes called just "processor", is an abbreviation for Central Processing Unit. That is the core of any laptop or computer or web server, since it runs each of the calculations and logical input/output procedures. Though the performance of an Internet site or an app is determined by other things as well, such as the amount of physical memory or the connection of the server, the rate at which a specific processor performs determines how quick an app shall be executed. Later-generation processors have numerous cores that can seriously improve their overall power and efficiency, since every core can control a variety of processes independently or several cores can take on one process which needs a significant computing power. Due to the fact that each and every core operates at a specific speed, this architecture can be seen as a number of individual processors working together.
