First four tasks = 8 seconds
Next four tasks = 8 seconds
Last two tasks = 8 seconds
The total number of seconds to perform all tasks is 24 seconds.
The throughput, which would be the number of tasks per second, is calculated by taking the number of tasks and dividing by the number of seconds:
10 tasks / 24 seconds = 5/12 or 0.4167 tasks per second
Answer: c)Roaming user profiles
Explanation:Roaming user profiles are those profiles that creates the copy from the local profile and get stored in the network server. Roaming user profiles haves the function of getting logged in any computer system that the user is processing by getting downloaded.
It has the advantage of not creating profiles on every computer system that user wants to login .Thus, the correct answer is option(c) because other profiles mentioned in the option cannot copy the profile in the server and so do not have capability to be accessed in other computer system.
Answer:

Explanation:
Considering the number are stored using binary notations.
If there are total 86 bits and 1 bit is used as sign bit. Then in total one can have
bit combinations since a bit can be either stored as 0 or as 1.
Therefore, the largest number that can be stored will be
.
To understand it in better way let's scale down the problem to 3 bits representation. The largest number that can be stored using 3 bits is 111 which in decimal form is 7 and is equal to
.
