time = 1/frequency = 1/(2.7*10^9)
=(1/2.7)* 10^-9 seconds
distance = speed*time
= 3*10^8 *(1/2.7)(10^-9)
= about 0.1 meter = 10 cm
A modern computer central processing unit chip (CPU) runs with a clock speed of 2.7 GHz. It can execute one operation in each of these clock cycles. (a) how many seconds long is one clock cycle? (b) Electrical signals travel at the speed of light How far can an electrical signal travel in one clock cycles? (c) Wires between the CPUs control unit and its cache memory (both on this chip), are about 2 cm long. How does this compare to how far an electrical signal can travel in one clock cycle?
I was confused because for a I know that v=2.7 GHz and t is what we need to find but I didn't know what d was for the formula v=t/d
