Five jobs arrive nearly simultaneously for processing and their estimated CPU cycles are, respectively: Job A = 2 ms, Job B = 12 ms, Job C = 15 ms, Job D = 7 ms, and Job E = 3 ms.
Using FCFS, in what order would they be processed? What is the total time required to process all five jobs? What is the average turnaround time for each of these five jobs?
This is an example with solution:
Five jobs arrive nearly simultaneously for processing and their estimated CPU cycles are, respectively: Job A = 12, Job B = 2, Job C = 15, Job D = 7, and Job E = 3 ms.
a. Using FCFS, and assuming the difference in arrival time is negligible, in what order would they be processed? What is the total time required to process all five jobs? What is the average turnaround time for all five jobs?
Answer: The order of processing for the given jobs = A->B->C->D->E.
Total time needed to process all the jobs = 12+2+15+7+3 = 39 ms.
Turn around time for job A = 12 ms.
Turn around time for job B = 15 ms.
Turn around time for job C = 30 ms.
Turn around time for job D = 37 ms.
Turn around time for job E = 40 ms.
Answer : Therefore, the average turnaround time = (12+15+30+37+40)/5 = 26.8 ms.
Order of processing is A, B, C, D, E and Total time to process and Average turnaround time is 39 ms and 24 ms
Turnover time and order of processing:Order of processing = A, B, C, D, E
Total time to process all five jobs = Job A + Job B + Job C + Job D + Job E
Total time to process all five jobs = 2 + 12 + 15 + 7 + 3
Total time to process all five jobs = 39 ms
Average turnaround time = [(2-0) + (2+12-0) + (2+12+15-0) + (2+12+15+7-0) + (2+12+15+7+3-0)] / 5
Average turnaround time = (2+14+29+36+39) / 5
Average turnaround time = 24 ms

Problem: For multi access control, there are two approaches, those based on channel partitioning, and those based on random access. In packet switching, there are two rather similar approaches as well, namely, circuit switching and package switching. Discuss the similarities and differences in these two problem domains and the corresponding approaches g
The similarity between the two systems is the ability to connect many different communication devices and transfer data between a sender and a receiver. The main difference is the need for a connection for both to work.
We can arrive at this answer because:
Circuit and package quotation is very important for the connections of different communication devices.Furthermore, these two systems are used efficiently when a data transfer is required.However, even being used for the same purposes, they have many differences between them.The biggest difference is the need for a connection, as package switching is done without the need for a connection, while circuit switching needs a connection to act.In addition, circuit switching is more widely used because of its ability to transfer data from one point to another via message transfer, while package switching is used when circuit switching is not available as it does the sending data more slowly across one drive.

What is the difference between (IF instructions & WHILE instructions )
0
를 들
T
!
Answer:
While statements determine whether a statement is true or false. If what’s stated is true, then the program runs the statement and returns to the first step. If what’s stated is false, the program exits the while and goes to the next statement. An added step to while statements is turning them into continuous loops. If you don’t change the value so that the condition is never false, the while statement becomes an infinite loop.
If statements are the simplest form of conditional statements, statements that allow us to check conditions and change behavior/output accordingly. The part of the statement following the if is called the condition. If the condition is true, the instruction in the statement runs. If the condition is not true, it does not. The if statements are also compound statements. They have a header (if x) followed by an indented statement (an instruction to be followed is x is true). There is no limit to the number of these indented statements, but there must be at least one.
Describe the two problems that appear in the construction of large programs that led to the development of encapsulation constructs.
Two problems that can lead to the development of encapsulation constructs when creating large programs are the complexity of data and the lack of security in sensitive data.
We can arrive at this answer because:
Encapsulation constructs are designed to prevent data from being invaded by unauthorized person.These constructions must be done without causing inconsistencies in the system, interfering with codes, and increasing the complexity of data. For this reason, large programs that present high complexity and difficult codes, demand the use of encapsulation constructs, so that their data does not become more complex.Encapsulation constructs are also necessary when there are flaws in data security and it is not possible to keep them away from the attack by intruders.Although there are other ways to accomplish these goals, encapsulation constructs are widely used because of their simplicity and efficiency.
