Required: Detect whether there is a deadlock in this system.

Answers

Answer 1

Upon observation of the graph, one  can see that there is a cycle involving processes P0, P1, P3, and P4. This cycle indicates a potential deadlock situation.

What is the deadlock

A state of stalemate  occurs when every process is anticipating a resource that is possessed by a different process, resulting in a loop of dependence that prevents progress.

By either utilizing the resource allocation graph or the Banker's algorithm, one can identify this situation. Identifying cycles in the graph is the method employed when using the resource allocation graph to detect a deadlock. The occurrence of a deadlock can be inferred from the existence of a cycle.

true/false: if the sub-expression on the left side of an || operator is true, the expression on the right side will not be checked.

Answers

It is true that if the sub-expression on the left side of an || operator is true, the expression on the right side will not be checked.

The boolean operator || (logical OR) returns true if either or both of the operands are true. It returns false if both operands are false. A short-circuit evaluation is used by the || operator. It means that if the sub-expression on the left side || operator evaluates to true, then the right side of the || operator will not be executed. It is pointless to do so since the overall result would still be true. Suppose a false value is on the left-hand side. The overall result will only be true if the right-hand side is true as well. Therefore, the right-hand side expression will be executed.

A program is written to compute the sum of the integers from 1 to 10. The programmer, well trained in reusability and maintainability, writes the program so that it computes the sum of the numbers from k to n. However, a team of security specialists scrutinizes the code. The team certifies that this program properly sets k to 1 and n to 10; therefore, the program is certified as being properly restricted in that it always operates on precisely the range 1 to 10. List different ways that this program can be sabotaged so that during execution it computes a different sum, for example, 3 to 20.

Answers

Answer:

See explanation section

Explanation:

See the program at the end of this solution

The program can be sabotaged if the source file is altered before running the program.

Take for instance,

Someone changes

for(int i =k;i<=n;i++)

to

for(int i =3;i<=20;i++)

This implies that no matter the user input, the program will only calculate the sum of 3 to 20

It is also possible that the program is altered by an external process.

Take for instance;

n = 10

k = 1

And the sum has been calculated for the range of k = 1 to 5.

Then the program is altered by an external process.

15 (sum of 1 to 5) will be displayed instead of 55 (sum of 1 to 10)

Program written in C++

#include<iostream>

using namespace std;

int main() {

int k.n,total=0;

cin>>k;

cin>>n;

//Assume k will always be less than n

for(int i =k;i<=n;i++) {

total+=i;

}

System.out.print(total);

return 0;

What do you understand by the following malicious programs (i) computer virus (ii) worm (iii) trojan horse (iv) sweeper (v) malware (vi) spyware.​

Answers

Answer:

Computer virus- A computer virus is a type of malware that attaches to another program (like a document), which can replicate and spread after a person first runs it on their system. For instance, you could receive an email with a malicious attachment, open the file unknowingly, and then the computer virus runs on your computer.

Worm virus- A computer worm virus is a standalone malware computer program that replicates itself in order to spread to other computers. It often uses a computer network to spread itself, relying on security failures on the target computer to access it. It will use this machine as a host to scan and infect other computers.

Trojan horse virus- A Trojan Horse (Trojan) virus is a type of malware that disguises itself as legitimate code or software. Once inside the network, attackers are able to carry out any action that a legitimate user could perform, such as exporting files, modifying data, deleting files or otherwise altering the contents of the device.

Sweeper virus- Sweeper virus is a fake anti-spyware program known to be an updated version of the rogue anti-spyware program Virus Doctor. Virus Sweeper is a program that when it is installed starts to perform actions such as scanning your computer without your permission.

Malware- Malware is any software intentionally designed to cause disruption to a computer, server, client, or computer network, leak private information, gain unauthorized access to information or systems, deprive access to information, or which unknowingly interferes with the user's computer security and privacy.

Spyware- Spyware is any software that installs itself on your computer and starts covertly monitoring your online behavior without your knowledge or permission. Spyware is a kind of malware that secretly gathers information about a person or organization and relays this data to other parties.
