Assume your computer clock runs at the speed of 2.5 GHz (G=10^9).
azamat

Answer:

a) T=4*10^{-4}μs

b) N=2.5*10^6 cycles

c) 10000 programs.

Explanation:

a) We know that the frequency is the inverse of the period, so:

f=\frac{1}{T}\\\\T=\frac{1}{f}\\T=4*10^{-10}s

1μs is equal to 1*10^{-6}s

so T=4*10^{-4}us

b) If in a second there are 2.5*10^9 cycles:

N=2.5*10^9*(1*10^{-3})=2.5*10^6 cycles

c) we have to make a conversion, we know that a program takes 100*10^(-3) milliseconds, that is, 1*10^(-4) seconds so in 1 second we can execute:

P=\frac{1s}{1*10^{-4}s}=10000

10000 programs.

Virtual Memory involves swapping between which 2 devices?
Darina [25.2K]

Answer:

Ram and the hard drive

Explanation:

A page of RAM is written to the harddisk and read back when it is needed again. That way it may seem you have more RAM than you actually have, at the cost of performance of course.
