Speed of Personal Computer and Classification

Over the last two decades there has been immense increase in the speed of personal computers. Technical Data used in the field explained in computer courses in Rawalpindi. The speed of a personal computer is essentially the maximum speed at which the CPU or the processor can perform the operations.

It is measured in clock rate, which is the rate in cycles per second measured in hertz. In the older classification there were 5 types of personal computers –– the PC (8088 CPU) PC-XT(80286 CPU), PC-AT (80386, 80486, and 80586 CPU), depending upon the clock rate of the CPU manufactured, as measured in Mz (Mega hertz). Some more details of computer courses in rawalpindi  are as under.

The speed of PC (8088) and PC-XT (80286), were about 4-8 Mz and 16-24 Mz respectively. In PC-AT (80386) the clock rate increased to 30-40 Mz and that of 80486 was around 60 Mz. In 80586 or Intel P5 CPU it increased to 80-100 Mz. Now we have processor with much higher clock rate ranging from 1.33 Ghz to 3.00 Ghz and above as currently manufactured by INTEL or AMD companies.

It is to be  remembered that these are the manufactured speed of the CPU. In actual work the speed realised (system speed) depends many other factors like, the operating system configuration, size of the programs, use of memory resident programs etc. TSK Training for Skills and Knowledge is the best institute in Rawalpindi Islamabad for Pakistani Students who wants to join computer courses in islamabad.
