Explanation:
ROMs that are read only memory are called non volatile because all of the data that are inside it happens to not get erased after shutting down the system or computer and starting it all over again. The opposite is this phenomenon is RAM. In RAM, they are being called volatile because all of the data that are inside it happens to get erased once shutting down of the system or computer occurs and it is being restarted.
This is telling us that ROM irrespective, stores data while it is on and also while it is off, it doesn't matter. It never forgets data, unless of course, in a situation whereby it is erased.

Answer:
2.6 seconds
Explanation:
We first start by calculating the speed up
The formula is given as:
n/1+(n-1)F
We have n = 3 which is the number of processors
F = 20% = percentage of algorithm
When we put values into the formula
3/1+(3-1)0.20
= 3/1+2*0.20
= 3/1+0.4
= 3/1.4
Speed up = 2.14
From here we calculate the expected time
T/speedups
= 5.6/2.14
= 2.6
Therefore the expected time is 2.6 seconds
