CPU, or Central Processing Unit, is that part of a home PC or a web server that executes all of the calculations. Each CPU functions at a particular speed and the larger it is, the swifter everything will 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 executed speedier, which will drastically contribute to the overall user experience. The modern generations of CPUs have 2 and more cores, each one running at a certain speed to guarantee a superior and faster performance. This kind of architecture enables the processor to control different processes at one time or several cores to handle a single process if it requires extra computing power to be carried out. However, additional factors like the amount of RAM or the connection that a particular server uses can also affect the efficiency of the websites hosted on it.
