CPU, or Central Processing Unit, is that element of a computer system or a server that runs all of the calculations. Each and every CPU runs at a certain speed and the bigger it is, the speedier everything will be processed, so in case you host resource-demanding web applications on a web server, for example, a powerful processor will enable them to be performed quicker, which will significantly contribute to the overall user experience. The newer generations of CPUs have 2 and more cores, each one functioning at a certain speed to guarantee a superior and faster performance. Such architecture makes it possible for the processor to manage different processes concurrently or several cores to handle 1 process if it requires extra computing power in order to be carried out. Of course, other variables like the amount of RAM or the connection that a specific server uses may also affect the performance of the websites hosted on it.
