10. Please select the factors below which increase the performance of a computer. Reduce Clock Cycle Time Increase instruction count Reduce number of clock cycles Increase clock rate Increase execution time
The formula for calculating the execution time of a computer:
So, a reduction in clock cycle time will reduce the total execution time of the CPU and thus increases the performance of the computer.
Similarly, a reduction in the number of clock cycles will reduce the total execution time of the CPU and thus increases the performance of the computer.
The number of instructions or instruction count is directly related to the number of clock cycles by the formula:
So, an increase in instruction count will increase the number of clock cycles which in turn will increase the overall execution time of the CPU. Thus, with an increase in instruction count, the performance of the computer decreases.
Clock rate is also known as clock speed. The higher clock rate means that the CPU is faster which means the CPU can execute instructions faster. So, with an increase in the clock rate, the performance of a computer increases.
The relation between the performance of a computer and the execution time of the CPU is given by the formula:
So an increase in execution time decreases the performance of computer.
