CPU, or Central Processing Unit, is that element of a home PC or a server that runs the calculations. Every single CPU functions at a particular speed and the bigger it is, the swifter everything will be processed, so in case you host resource-demanding web programs on a hosting server, for instance, a fast processor will enable them to be carried out quicker, which will significantly contribute to the whole user experience. The more recent generations of CPUs have 2 and more cores, each running at a particular speed to guarantee a superior and quicker performance. This sort of architecture makes it possible for the processor to manage various processes at one time or a number of cores to handle a single process if it needs more computing power to be carried out. Obviously, additional factors including the amount of RAM or the connection that a specific server uses can also affect the performance of the Internet sites hosted on it.
