Explanation:
question a) answer:
At the moment when it sends the package, then it has a waiting time for the acknowledgement from the receiver, however, the time will be split in two when the frameset size becomes two, meaning that two packages have been sent together, causing the receiver to acknowledge only one package.
question b) answer:
The timeout is equal to two times.
In cases when the frame size is 3, the frame will be lost since the timeout turns to be 2 times. Because the sender has to wait for the acknowledgement, therefore it will send other of the parcels.

If the propagation delay through a full-adder (FA) is 150 nsec, what is the total propagation delay in nsec of an 8-bit ripple-carry adder
Answer:
270 nsec
Explanation:
Ripple-carry adder is a combination of multiple full-adders. It is relatively slow as each full-adder waits for the output of a previous full-adder for its input.
Formula to calculate the delay of a ripple-carry adder is;
= 2( n + 1 ) x D
delay in a full-adder = 150 nsec.
number of full-adders = number of ripple-carry bits = 8
= 2 ( 8 + 1 ) x 150
= 18 x 150
= 270 nsec

Suppose one machine, A, executes a program with an average CPI of 1.9. Suppose another machine, B (with the same instruction set and an enhanced compiler), executes the same program with 20% less instructions and with a CPI of 1.1 at 800MHz. In order for the two machines to have the same performance, what does the clock rate of the first machine need to be
Answer:
the clock rate of the first machine need to be 1.7 GHz
Explanation:
Given:
CPI of A = 1.9
CPI of B = 1.1
machine, B executes the same program with 20% less instructions and with a CPI of 1.1 at 800MHz
To find:
In order for the two machines to have the same performance, what does the clock rate of the first machine need to be
Solution:
CPU execution time = Instruction Count * Cycles per Instruction/ clock rate
CPU execution time = (IC * CPI) / clock rate
(IC * CPI) (A) / clock rate(A) = (IC * CPI)B / clock rate(B)
(IC * 1.9) (A) / clock rate(A) = (IC * (1.1 * (1.0 - 0.20)))(B) / 800 * 10⁶ (B)
Notice that 0.20 is basically from 20% less instructions
(IC * 1.9) / clock rate = (IC * (1.1 * (1.0 - 0.20))) / 800 * 10⁶
(IC * 1.9) / clock rate = (IC*(1.1 * ( 0.8))/800 * 10⁶
(IC * 1.9) / clock rate = (IC * 0.88) / 800 * 10⁶
clock rate (A) = (IC * 1.9) / (IC * 0.88) / 800 * 10⁶
clock rate (A) = (IC * 1.9) (800 * 10⁶) / (IC * 0.88)
clock rate (A) = 1.9(800)(1000000) / 0.88
clock rate (A) = (1.9)(800000000) / 0.88
clock rate (A) = 1520000000 / 0.88
clock rate (A) = 1727272727.272727
clock rate (A) = 1.7 GHz

The Beaufort Wind Scale is used to characterize the strength of winds. The scale uses integer values and goes from a force of 0, which is no wind, up to 12, which is a hurricane. The following script first generates a random force value. Then, it prints a message regarding what type of wind that force represents, using a switch statement. If random number generated is 0, then print "there is no wind", if 1 to 6 then print "this is a breeze", if 7 to 9 "this is a gale", if 10 to 11 print "this is a storm", if 12 print "this is a hurricane!". (Hint: use range or multiple values in case statements like case {1,2,3,4,5,6})
Required:
Re-write this switch statement as one nested if-else statement that accomplishes exactly the same thing. You may use else and/or elseif clauses.
ranforce = randi([0, 12]);
switch ranforce
case 0
disp('There is no wind')
case {1,2,3,4,5,6}
disp('There is a breeze')
case {7,8,9}
disp('This is a gale')
case {10,11}
disp('It is a storm')
case 12
disp('Hello, Hurricane!')
end
Answer:
The equivalent if statements is:
ranforce = randi([0, 12]);
if (ranforce == 0)
disp('There is no wind')
else if(ranforce>0 && ranforce <7)
disp('There is a breeze')
else if(ranforce>6 && ranforce <10)
disp('This is a gale')
else if(ranforce>9 && ranforce <12)
disp('It is a storm')
else if(ranforce==12)
disp('Hello, Hurricane!')
end
Explanation:
The solution is straight forward.
All you need to do is to replace the case statements with corresponding if or else if statements as shown in the answer section

In C language, the asterisks, ' * ', and the ampersand, ' & ', are used to create pointers and references to pointers respectively. The asterisks are used with unique identifiers to declare a pointer to a variable location in memory, while the ampersand is always placed before a variable name as an r_value to the pointer declared.

There is an error in the while loop. What should be fixed?
1. Add a colon to the end of the statement
2. Begin the statement with the keyword count
3. Change the parentheses around the test condition to quotation marks
4. Use quotation marks around the relational operator
This is python code.
In python, you are supposed to put a colon at the end of while loops. This code does not have a colon after the while loop, therefore, you need to add a colon to the end of the statement.
The error to be fixed in the while loop is to add a colon at the end of the while statements.
x = 1
while (x<26)
print(x)
x = x + 1
This is the right code;
x = 1
while(x < 26):
print(x)
x = x + 1
The actual code , the while statement is missing a colon at the end of it.
The code is written in python. In python while or for loops statements always ends with a colon.
In the error code, there was no colon at the end of the while loop.

In a system where Round Robin is used for CPU scheduling, the following is TRUE when a process cannot finish its computation during its current time quantum? The process will terminate itself. The process will be terminated by the operating system. The process's state will be changed from running to blocked. None of the mentioned.
Answer:
B. The process will be terminated by the operating system.
Explanation:
When Round Robin is used for CPU scheduling, a time scheduler which is a component of the operating system is used in regulating the operation. A time limit is set for each of the processes to be run.
So, when a process fails to complete running before its time elapses, the time scheduler would log it off and return it to the queue. This queue is in a circular form and gives each of the processes a chance to run its course.
Based on the information given regarding CPU scheduling, the correct option is C. The process's state will be changed from running to blocked.
It should be noted that in a system where Round Robin is used for CPU scheduling, when a process cannot finish its computation during its current time quantum, the process's state will be changed from running to blocked.
It should be noted that a prices transition to a blocked state occurs when it's waiting for some events like a particular resource becoming available.
