Answer:
Encapsulation
Explanation:
There are seven layers in the OSI network model. These layers are, application, presentation, session, transport, network, data-link and physical layer.
Each layer of the OSI model has a PDU or protocol data unit. These PDUs are form by encapsulation.
The application, presentation and session data. When it moves to the transport layer, it is encapsulated within the transport header. This new pdu is called segment.
This process continues in network and data-link to give packet and frame PDUs respectively.
Answer:
Reference
Explanation:
The Reference type variable is such type of variable in C# that holds the reference of memory address instead of value. Examples for reference type are classes, interfaces, delegates and arrays.
We can pass parameters to the method by reference using <em>ref </em>keyword
It’s mandatory to initialize the variable value before we pass it as an argument to the method in c#
For example,
int x = 10; // Variable need to be initialized
Add(ref x); // method call
If you pass parameters by reference in method definition, any changes made to it affect the other variable in method call.
Here's a sample program:
using System;
namespace ConsoleApplication
{
public class Test
{
public static void Main()
{
int i = 10;
Console.WriteLine("i=" + i);
Add(ref i);
Console.WriteLine("i=" + i);
Console.ReadLine();
}
public static void Add( ref int j)
{
j = j + 10;
Console.WriteLine("j="+j);
}
}
}
Output:
i=10
j=20
i=20
