CPU, which is frequently called just "processor", is an abbreviation for Central Processing Unit. This is the core of each and every laptop or computer or web server, as it performs all of the calculations and logical input/output procedures. Even though the performance of a website or an app is determined by other things as well, like the amount of physical memory or the online connectivity of the web server, the pace at which a particular processor performs determines how soon an application will be executed. Later-generation processors have several cores which can considerably increase their overall power and efficiency, due to the fact that every core can control numerous processes separately or a few cores can deal with 1 process that needs a substantial computing power. Due to the fact that each and every core works at a particular speed, this architecture can be viewed as a few separate processors cooperating.
