Lesson 12 - Computer Performance
Have you ever wondered why your computer is slow. In this lecture you will learn the basics pertaining to computer performance. The user can judge the performance of a PC according to how quickly tasks are performed. There are a number of factors that determine the overall operating speed of a PC: The clock speed and amount of cores of the CPU The capacity and speed of the RAM The capacity and speed of the HDD (Hard Disk Drive). The number of applications running The Memory size and speed of the GPU Condition of Operating System Start up programs The relative importance of all these factors will depend on the nature and number of the tasks being performed. A task involving thousands of complex calculations will depend heavily on CPU speed, whilst one involving huge quantities of data will be more affected by RAM size and HDD access times. Tasks involving the Internet will probably be restricted by Internet connection speed.
