Question

If a processor clock is rated as 1250 million cycles per second, then its clock period is

Answer 1

The clock period is 8 x 10⁻¹⁰ sec

Explanation:

we know that Frequency is defined as the number of cycles in one second

Number of cycle in 1 sec = 1250 million

=> Frequency = 1250 Mhz

we know that time period is the inverse of frequency and is defined as the time taken by one cycle.

=> T = 1/F

= 1/1250 x 10⁶

= 8 x 10⁻¹⁰ sec

Hence the clock period is 8 x 10⁻¹⁰ sec

Answer 2

If a processor clock is rated as 1250 million cycles per second, then its clock period is

8 * 10-10 sec

This is because the clock period is calculated by using the formula

Clock period = 1/ clock cycle = 1/(1250*10⁶)

which is equal to the value  8 * 10-10 sec

Thus, among all the options given, the correct answer is 8 * 10-10 sec
