Group of answer choices.

A. Ensure that cell phones and laptops cannot communicate.

B. Give each country its own internet language.

C. Ensure that new technologies and devices that haven't been invented yet can all use the same methods of communication.

D. Assure that computers and other devices don't pollute the environment.

Answer:

C. Ensure that new technologies and devices that haven't been invented yet can all use the same methods of communication.

Explanation:

OSI model stands for Open Systems Interconnection. The seven layers of OSI model architecture starts from the Hardware Layers (Layers in Hardware Systems) to Software Layers (Layers in Software Systems) and includes the following;

1. Physical Layer

2. Data link Layer

3. Network Layer

4. Transport Layer

5. Session Layer

6. Presentation Layer

7. Application Layer

Each layer has its unique functionality which is responsible for the proper functioning of the communication services.

Additionally, a standard framework for the transmission of informations on the internet, it is known as the internet protocol suite or Transmission Control Protocol and Internet Protocol (TCP/IP) model. One of the very basic rule of the TCP/IP protocol for the transmission of information is that, informations are subdivided or broken down at the transport layer, into small chunks called packets rather than as a whole.

Hence, communication protocols, sets of rules agreed to by all parties, are designed in order to ensure that new technologies and devices that haven't been invented yet can all use the same methods of communication.

This ultimately implies, there exist standard frameworks and protocols that are designed and developed to serve pre-existing technologies and devices, as well as those that would be invented in the future.

For example, SMTP is an acronym for Simple Mail Transfer Protocol and it uses the standard port number of 25 to provide clients with requested services on an internet-enabled device.

Assume the availability of class named DateManager that provides a static method, printTodaysDate, that accepts no arguments and

Ira Lisetskai [31]

Answer:

Hi!

The answer is:

DateManager dm = new DateManager(); // Instanciate.

dm.printTodaysDate; // Calls the method.

Explanation:

If you are working on object-oriented programming, then:

First, you have to instanciate the class DataManger.

Then, you can call printTodaysDate on the instance dm of DataManager.

A report has a column of totals, with each total adding to the cell above it. What kind of calculated figure is this?

Alexxx [7]

ANSWER:

The correct answer is Running Sum.

Explanation:

A report has a column of totals, with each total adding to the cell above it. Such type of calculated figure is called the Running Sum.

Running sum is also called the Partial Sum. In such type of summation, the values in the sequence is added to get a final result and then if a new number comes, it is again added to the grand sum, and in this way the sequence continues. Every new entry is added to the previous sum to get another sum.

Write a program that first gets a list of integers from input. The input begins with an integer indicating the number of integer

dalvyx [7]

Answer:

The program is as follows:

def output_ints_less_than_or_equal_to_threshold(user_values, upper_threshold):

for i in user_values:

if i <= upper_threshold:

print(i,end=" ")

def get_user_values():

user_values = []

n = int(input())

for i in range(n):

num = int(input())

user_values.append(num)

upper_threshold = int(input())

output_ints_less_than_or_equal_to_threshold(user_values, upper_threshold)

get_user_values()

Explanation:

This defines the output_ints_less_than_or_equal_to_threshold method

def output_ints_less_than_or_equal_to_threshold(user_values, upper_threshold):

This iterates through user_values

for i in user_values:

For every item in user_values

if i <= upper_threshold:

This prints all items less than or equal to the upper threshold

print(i,end=" ")

This defines get_user_values method

def get_user_values():

This creates an empty list

user_values = []

This gets the number of inputs

n = int(input())

This iterates through n

for i in range(n):

This gets input for every item of the list

num = int(input())

This appends the input to the list

user_values.append(num)

This gets input for upper threshold

upper_threshold = int(input())

This calls output_ints_less_than_or_equal_to_threshold method

output_ints_less_than_or_equal_to_threshold(user_values, upper_threshold)

The main begins here; This calls get_user_values method

get_user_values()
