Computer performance

In computing, computer performance is the amount of useful work accomplished by a computer system. Outside specific contexts, computer performance is estimated in terms of accuracy, efficiency and speed of executing computer program instructions. When it comes to high computer performance, one or more of the following factors might be involved:
