Answer:
Means no matter how many processors you use, speed up never increase from 10 times.
Explanation:
If a problem of size W has a serial component Ws,then performance using parallelism:
Using Amdahl's Law:
Tp = (W - Ws )/ N + Ws
Here, Ws = .1,
W - Ws = .9
Performance Tp = (.9 / N) + .1
---------------------------------------------------------
Speed Up = 1 / ( (.9 / N) + .1)
If N -> infinity, Speed Up <= 10
Means no matter how many processors you use, speed up never increase from 10 times.

Although when Tim has such an outdated network system which is used as a backup by his corporation. Then hard drive may have gone wrong and required replacement. The connector used by the hard disk drive is not something he has ever seen before, but he upload photos of that on the community board of the organization to aid determine what kind of hard disk drive they will also have to order.
So, according to the following scenario he required SCSI cable.
