CPU, or Central Processing Unit, is that part of a home PC or a server that executes each of the calculations. Every single CPU operates at a specific speed and the bigger it is, the swifter everything shall be processed, so in case you host resource-demanding web apps on a hosting server, for instance, an effective processor will allow them to be carried out speedier, which will significantly contribute to the entire user experience. The modern generations of CPUs have 2 and more cores, each of them operating at a particular speed to ensure a much better and quicker performance. This type of architecture makes it possible for the processor to manage different processes at one time or several cores to address a single process if it needs more computing power to be executed. Naturally, other factors including the amount of RAM or the connection that a given web server uses can also affect the efficiency of the websites hosted on it.
