The answer is firewall. It is a network security device that observes inbound and outbound network traffic and chooses whether to allow or block specific traffic based on a well-defined set of security rules. Firewalls have been a first line of protection in network security for over 25 years. The firewall present a barrier between measured and secured internal networks that can be trusted and untrusted outside networks, for example the Internet. A firewall can be software, hardware, or even both.
Answer:
Explanation:
One group of students did an experiment to study the movement of ocean water. The steps of the experiment are listed below.
Fill a rectangular baking glass dish with water.
Place a plastic bag with ice in the water near the left edge of the dish.
Place a lighted lamp near the left edge of the dish so that its light falls directly on the plastic bag.
Put a few drops of ink in the water.
The student did not observe any circulation of ink in the water as expected because the experiment had a flaw. Which of these statements best describes the flaw in the experiment? (2 points)
Not enough ink was added.
Not enough water was taken.
The dish was too small for the experiment.
The lamp and the ice bag were at the same place.
Answer: Both A and B
Explanation: Transport layer is the level of the OSI model which is helpful in maintaining the overall network communication.The application process that is being executed in the layers of architecture gets logical communication through transport layer.
It has the ability to connect the data that has been divided into section for the transportation.It can also act on the transport header ,which finds the transmission flow of specific data when not required.
Intranet is the answer to this question.
Google definition: An intranet is a network based on TCP/IP protocols (an internet) belonging to an organization, usually a corporation, accessible only by the organization's members, employees, or others with authorization.
Answer:
// here is code in C++.
#include <bits/stdc++.h>
using namespace std;
// function to compute sum and product
void square(int input)
{
// variable to store the square of number
long long squ_num;
calculate the square of number
squ_num=pow(input,2);
// print the output
cout<<"square of "<< input<<" is: "<<squ_num<<endl;
}
// driver function
int main()
{
int n;
// read the number until user enter 0
do{
cout<<"enter a number!! (0 to stop):";
// read the input from user
cin>>n;
// call the function to calculate square of input number
square(n);
}while(n!=0);
return 0;
}
Explanation:
Declare a variable "n" to read the input number from user.Call the function square() with parameter "n".In this function, it will calculate the square of the input number and print it.This will repeat until user enter 0 as input.Program will ends when user give 0 as input.
Output:
enter a number!! (0 to stop):5
square of 5 is: 25
enter a number!! (0 to stop):7
square of 7 is: 49
enter a number!! (0 to stop):11
square of 11 is: 121
enter a number!! (0 to stop):0
