What opeartions will acquire memory from heap? Select all that apply. Group of answer choices malloc new free declaraion

Answers

Answer 1

Answer:

malloc, new

Explanation:

Heap memory is that part of the memory which is allocated to the JVM and it is shared by all the executing threads in the application. This memory is used by the programming languages to store the global variables. All the global variables are stored in the heap memory by default. This memory is also known as the dynamic memory.

In C programming, the library function, malloc is mainly used to allocate the block of the memory on the heap.

The new operation also acquires memory form the heap.

Thus, the answer is 'malloc' and 'new'.

The process of providing only the essentials and hiding the details is known as abstraction.

What is abstraction?

Abstraction in its main sense is a conceptual process wherein general rules and concepts are derived from the usage and classification of specific examples, literal ("real" or "concrete") signifiers, first principles, or other methods.

"An abstraction" is the outcome of this process—a concept that acts as a common noun for all subordinate concepts and connects any related concepts as a group, field, or category.

Conceptual abstractions may be formed by filtering the information content of a concept or an observable phenomenon, selecting only those aspects which are relevant for a particular purpose. For example, abstracting a leather soccer ball to the more general idea of a ball selects only the information on general ball attributes and behavior.

Therefore, The process of providing only the essentials and hiding the details is known as abstraction.

Answer & Explanation:

The program you added to the question is correct, and it works fine; It only needs to be properly formatted.

So, the only thing I did to this solution is to re-write the program in your question properly.

Modify the solution to PP 11.1 such that it catches and handles the exception if it is thrown. Handle the exception by printing an appropriate message, and then continue processing more strings.

Answers

Answer:

Explanation:

The following code is written in Java. After finding the PP 11.1 file online I added the try/catch to the code as requested by the question. The program takes the input from the user, checks it's length, and if it contains more than 20 characters it throws the exception. This exception states that "the string has more than 20 characters" and then continues processing more strings until the user enters "DONE". The program has been tested and the output can be seen in the attached image below. Due to technical difficulties I have added the code as a txt file below.

Kareem is working on a project for his manager. He has a few questions for a co-worker who he knows is knowledgeable on the subject. As they're discussing some of the topics, he gives the co-worker permissions to the resources so they can look at the information on their own. Which of the following access control methods does Kareem's company use?

a. DAC
b. RBAC
c. MAC
d. TSAC

Answers

Answer: RBAC

Explanation:

The access control methods that Kareem's company uses us the role based access control.

The Role-based access control (RBAC) simply means assigning permissions to users based on the role that such individual plays within an organization.

RBAC is a simple approach to access management and is typically less prone to error than in a scenario whereby permissions are assigned to users individually. Access rights are given to the workers based on what their job entails and what is needed and other information which isn't needed won't be accessible to them.

Your new trainee is interested in ACLs (access control lists). He asks you want they can be used for. What should you tell him? A. Protect hosts from viruses.B. Classify network traffic.C. Provide high network availability.D. IP route filtering.

Answers

Answer:

B. Classify network traffic.

D. IP route filtering.

Explanation:

An access control can be defined as a security technique use for determining whether an individual has the minimum requirements or credentials to access or view resources on a computer by ensuring that they are who they claim to be.

Simply stated, access control is the process of verifying the identity of an individual or electronic device. Authentication work based on the principle (framework) of matching an incoming request from a user or electronic device to a set of uniquely defined credentials.

Basically, authentication and authorization is used in access control, to ensure a user is truly who he or she claims to be, as well as confirm that an electronic device is valid through the process of verification

Hence, an access control list primarily is composed of a set of permissions and operations associated with a network or file.

In Computer networking, access control lists (ACLs) can be used to perform the following tasks;

I. Classify network traffic: it can be used to classify the different networks on a router and define whether packets are rejected or accepted.

II. Internet protocol (IP) route filtering: any internet protocol (IP) address that's is not on the accept list would be refused permission into accessing a network. Thus, ACLs can either deny or accept IP addresses depending on the routing table configured on the router.

Answer:

k = 3

Explanation:

K independent file servers

Average "uptime" of each server = 98%

To achieve 99.99% probability by the intranet

given that each server has an uptime = 98%

For the intranet to achieve 99.99% probability we have to choose more than 2 servers ( i.e. 3 servers ) incase any of the server goes down.

As each server posses an uptime of 98% it is almost impossible for all 3 servers to go down at the same time hence value of K = 3

It should be noted that the value of k to achieve 99.99 percent probability will be 3.

How to solve the probability

From the information given, k is simply the independent file servers.

Also, the average uptime of each server is given as 98%. For the intranet to achieve 99.99% probability, it should be noted that more than 2 servers will be chosen.

In this case, it'll be impossible for the three servers to go down.
