A _______ spans a geographic area like a city,is larger than a LAN and smaller than WAN

Answers

Answer:

metropolitan area network (MAN)

Explanation:

A local area network (LAN) refers to a group of personal computers (PCs) or terminals that are located within the same general area and connected by a common network cable (communication circuit), so that they can exchange information from one node of the network to another. A local area network (LAN) is typically used in small or limited areas such as a set of rooms, a single building, school, hospital, or a set of well-connected buildings.

On the other hand, a metropolitan area network (MAN) spans a geographic area like a city, is larger than a local area network (LAN) and smaller than wide area network (WAN).

Basically, a metropolitan area network (MAN) is formed by an aggregation of multiple local area network (LAN) that are interconnected using backbone provided by an internet service provider (ISP). A metropolitan area network (MAN) spans for about 5 kilometers to 50 kilometers in size.

Correct Answer: Mary has been given access to all of the file servers. Correct Answer: Jill has been given access to all of the files on one server. Correct Answer: Lenny has been given access to files that he does not need for his job.

Answers

Answer: Wanda has been given access to the files that she needs for her job.

Explanation:

The principle of least privilege is when a user is only given the minimum level of permissions that he or she needs to perform a particular job function. This helps in reducing the risk of attackers having access to data.

The best example of the principle of least privilege is Wanda has been given access to the files that she needs for her job. Given access to all of the file servers or access to all of the files on one server is incorrect.

Answer:

Wanda

Explanation:

Reason being is that least privilege gets only the things you need for the job, nothing more or less.

¿Qué algoritmos de encriptación utilizan una clave para cifrar los datos y una clave diferente para descifrarlos?

Answers

Answer:

Asimétrica

Explanation:

Los algoritmos de encriptación sirven para que solo el destinariario y receptor de los datos logren acceder a la información, es decir que inmediatamente que es enviada la información, solo puede ser legible para quien tenga un código de acceso, al mismo quien envía necesita una clave diferente para enviar lo datos. es un algoritmo asimétrico porqué el emisor y el receptor usan claves diferentes de encriptación.

Write a structured algorithm that prompts the
user to input two numbers. The algorithm should
multiply both numbers and then prompt the
user to enter the answer. The algorithm should
compare the answer entered with that calculated
and output "correct answer" or "incorrect answer"
accordingly. At the start, input how many sums
will be done.

Answers

Answer:

Step 1 : Start

Step2 : Input first number, num1

Step3 : Input second number, num2

Step4 : product - - > num1 * num2 (product of num1 and num2)

Step5 : Input product, myanswer

Step6 : comparison - - - > correct or incorrect based on myanswer and product

Step6: print(comparison)

Step7: End

Explanation:

Algorithm is a sequence of instructions a computer is expected to follow to solve a particular problem.

Required :

Two inputs ; num1 and num2

Expected output

Algorithm :

Step 1 : Start

Step2 : Input first number, num1

Step3 : Input second number, num2

Step4 : product - - > num1 * num2 (product of num1 and num2)

Step5 : Input product, myanswer

Step6 : comparison - - - > correct or incorrect based on myanswer and product

Step6: print(comparison)

Step7: End

The two numbers to multiply are entered ; the product is calculated by the program ; the the user inputs his or her own expecteted product ;

Both are compared and the output of the comparison is displayed (either correct oe incorrect)

IT technicians are setting up a new file server for a school. Describe the benefits and
drawbacks of using a command line interface (CLI) rather than a graphical user interface
(GUI) to set up a new file server.

Answers

Answer:

The benefits of using the command line interface for setting up a file server are;

1) The command line interface (CLI) is faster than other interfaces and can easily handle tasks which are repeating such as creating folders for users on the server

2) The CLI requires less time for processing with the CPU, and it takes up less memory such that the file Server is not slowed down during the file setup process

3) The system resources required are few

The drawbacks are;

1) The CLI is confusing to those who are not exposed to programming as the commands the user needs to learn to before they can setup setup the new file server

2) The users needs to be very accurate in terms of spelling errors as that will lead to failure of the program, there are no spell check, and a mistype can lead to the entire coding process being restarted from the beginning
