You just received a message from the internet which was encrypted with asymmetric encryption. what do you need to do to read the
Bezzdna [24]
Assuming the data was encrypted with YOUR public key, you'll need YOUR private key to decrypt it. That's answer e.

a and b are not solutions by themselves, of course you need to use the decryption algorithm, but a key goes with it.

c would be about symmetric encryption, but this is asymmetric, so different keys are used for encryption and decryption

d is possible, but it would mean anyone can decrypt it (after all the key is public), so then there's no point in encrypting it in the first place.

So e is the only logical answer.

Using Amdahl’s Law, calculate the speedup gain of an application that has a 60 percent parallel component for (a) two processing
Nina [5.8K]

Answer:

a) Speedup gain is 1.428 times.

b) Speedup gain is 1.81 times.

Explanation:

in order to calculate the speedup again of an application that has a 60 percent parallel component using Anklahls Law is speedup which state that:

t=\frac{1 }{(S + (1- S)/N) }

Where S is the portion of the application that must be performed serially, and N is the number of processing cores.

(a) For N = 2 processing cores, and a 60%, then S = 40% or 0.4

Thus, the speedup is:

t = \frac{1}{(0.4 + (1-0.4)/2)} =1428671

Speedup gain is 1.428 times.

(b) For N = 4 processing cores and a 60%, then S = 40% or 0.4

Thus, the speedup is:

t=\frac{1}{(0.4 + (1-0.4)/4)} = 1.8181

Speedup gain is 1.81 times.
