B. Noise on the line might be causing line blunders, which can bring about information misfortune. Reverberation checks and equality checks can assist with recognizing and right such mistakes.
C. If information is being lost, reverberation checks and equality checks ought to likewise help; notwithstanding, the issue might be that an intruder is blocking messages and altering them. Message arrangement numbering will assist with deciding whether messages are being lost, and in the event that they are maybe a solicitation reaction strategy ought to be executed that makes it hard for gatecrashers to dodge.
D. In the event that messages are being postponed, a significant client request or other data could be missed. As in thing c, message arrangement numbering and solicitation reaction methods ought to be utilized.
E. Messages modified by intruders can have an extremely negative effect on client provider relations if orders are being changed. For this situation, information encryption is important to keep the gatecrasher from perusing and changing the information. Additionally, a message succession numbering strategy is important to ensure the message isn't erased.

Two of the most fundamental functions for dealing with interprocess communication are read() and write(). Consider the following otherwise valid C program:int r, pipeFDs[2];
char message[512];
pid_t spawnpid;
pipe(pipeFDs);
spawnpid = fork();
switch (spawnpid)
{
case 0:
close(pipeFDs[0]); // close the input file descriptor
write(pipeFDs[1], "hi process, this is the STUFF!!", 21);
break;
default:
close(pipeFDs[1]); // close output file descriptor
r = read(pipeFDs[0], message, sizeof(message));
printf("Message received from other: %s\n", message);
break;
}
Select each of the following answers that is correct. CAN BE MULTIPLE CHOICES...
(1) The read() call may block until data becomes available
(2) When the read() call returns, this one call will return all of the data that was sent through the pipe, which is different behavior than if this was a socket
(3) If the read() call blocks, the process will be suspended until data arrives
(4) The write() call will return before all of the data has been written, if the corresponding read() call blocks mid-transfer
(5) Pipes can fill, which will cause the write() call to block until the read() call is able to read data from the pipe
Answer: Provided in the explanation section
Explanation:
int r, pipeFDs[2];
char message[512];
pid_t spawnpid;
pipe(pipeFDs);
spawnpid = fork();
switch (spawnpid)
{
case 0:
close(pipeFDs[0]); // close the input file descriptor
write(pipeFDs[1], "hi process, this is the STUFF!!", 21);
break;
default:
close(pipeFDs[1]); // close output file descriptor
r = read(pipeFDs[0], message, sizeof(message));
printf("Message received from other: %s\n", message);
break;
}
Observation of the program:
The read() call may block until data becomes available If the read() call blocks, the process will be suspended until data arrives Pipes can fill, which will cause the write() call to block until the read() call is able to read data from the pipe⇒ Therefore,Option 1,3 and 5 correct

Suppose that class OrderList has a private attribute double cost[100] which hold the cost of all ordered items, and a private attributes int num_of_items which hold the number of items ordered. For example, if num_of_items is 5, then cost[0], cost[1], ..., cost[4] hold the cost of these 5 items. Implement the member function named total_cost which returns the total cost of this OrderList.
Answer:
OrderList.java
public class OrderList { private double cost[]; private int num_of_items; public OrderList(){ cost = new double[100]; } public double total_cost(){ double total = 0; for(int i=0; i < num_of_items; i++){ total += cost[i]; } return total; } }Main.java
public class Main { public static void main(String[] args) { OrderList sample = new OrderList(); double totalCost = sample.total_cost(); } }Explanation:
Firstly, define a class OrderList with two private attributes, cost and num_of_items (Line 1-3). In the constructor, initialize the cost attribute with a double type array with size 100. Next, create another method total_cost() to calculate the total cost of items (Line 9-15). To implement the total_cost member function, create an OrderList instance and use that instance to call the total_cost() and assign it to totalCost variable.

CASE II AziTech is considering the design of a new CPU for its new model of computer systems for 2021. It is considering choosing between two (2) CPU (CPUA and CPUB) implementations based on their performance. Both CPU are expected to have the same instruction set architecture. CPUA has a clock cycle time of 60 ns and CPUB has a clock cycle time of 75 ns. The same number of a particular instruction type is expected to be executed on both CPUs in order to determine which CPU would executes more instructions. CPUA is able to execute 2MB of instructions in 5*106 clock cycles. CPUB executes the same number of instructions in 3*106 clock cycles. a) Using the MIPS performance metric, which of the two (2) CPU should be selected to be implemented in the new computer system. Justify your choice. b) Compute the execution time for both CPUs. Which CPU is faster?
Answer:
(a)The CPU B should be selected for the new computer as it has a low clock cycle time which implies that it will implement the process or quicker when compared to the CPU A.
(b) The CPU B is faster because it executes the same number of instruction in a lesser time than the CPU A .
Explanation:
Solution
(a)With regards to the MIPS performance metric the CPU B should be chosen for the new computer as it low clock cycle time which implies that it will implement the process or quicker when compared to the CPU A and when we look at the amount of process done by the system , the CPU B is faster when compared to other CPU and carries out same number of instruction in time.
The metric of response time for CPU B is lower than the CPU A and it has advantage over the other CPU and it has better amount as compared to CPU A, as CPU B is carrying out more execution is particular amount of time.
(b) The execution can be computed as follows:
Clock cycles taken for a program to finish * increased by the clock cycle time = the Clock cycles for a program * Clock cycle time
Thus
CPU A= 5*10^6 * 60*10^-9 →300*10^-3 →0.3 second (1 nano seconds =10^-9 second)
CPU B= 3 *10^6 * 75*10^-9 → 225*10^-3 → 0.225 second
Therefore,The CPU B is faster as it is executing the same number of instruction in a lesser time than the CPU A

Probability of theft in an area is 0.03 with expected loss of 20% or 30% of things with probabilities 0.55 and 0.45. Insurance policy from A costs $150 pa with 100% repayment. Policy with B, costs $100 pa and first $500 of any loss has to be paid by the owner. Which data mining technique can be used to choose the policy?
Answer:
Decision trees
Explanation:
Decision trees mainly include categorization and estimation. It is often used as a measure of selection. This also encourages the usage and choice of particular data within the overall structure.
In the given situation, we should choose Policy A has cost $150 as it has 100% repayment while on the other hand Policy B has cost $100 and the first $500 of loss would be paid by the owner
So for choosing the policy, we use the decision tree data mining technique as we have to take the decision with respect to minimizing the cost
Data mining technique which can be used to choose the policy is decision tree.
The data mining technique that can be used are as follows,
Categorization and estimate are the two major functions of decision trees,Decision tree frequently used as a selection criterion. This promotes the use and selection of specific data within the broader framework.According to given data,
We should pick Policy A, which costs $150 and has a 100% payback rate.Whereas, the owner would be responsible for the first $500 of loss under Policy B, which costs $100.Here choosing the correct policy, decision tree is used.
