1.4 Factors that Determine the Performance of a Computer

The poor or good performance of the computer could be determined easily through analyzing the speed and power of the computer. There are certain factors that determines the speed and accurate performance of the computer (Avoine, Junod and Oechslin, 2007). The major factor is the less number of viruses. It is not good for the performance of the machine. Virus can hamper the speed factor and can definitely affect the whole functioning of the machine.

Other than that processor speed, instructions set etc. these also have direct relevancy with the performance of computer. For speed of the computer the memory of the system is also required to be assessed in proper way. It should be compatible with the system motherboard as well. If the Hard drive is full then also the performance of the computer could be hampered. Other than this the operating system also affects the performance as new computer is generally virus free and files also remain managed (Magnusson, 2002).

Other than this the system memory speed is also required to be handled. If the memory system is occupied then it works against the performance of the computer. Internet also works smoothly if the operating system is proper and effectively installed within the computer. Thus it is clear that all the configurations should be compatible to each another just for the purpose of increasing the performance of computer.
