Answer:
The answer is True
Explanation:
Switches are responsible for connecting computers within a network and it belongs only to its local network. Its responsibility is to filter and forward packets between LAN segments. They operate on layer two (2) and sometime layer three (3) of the OSI Model.
Routers on the other hand, are responsible for the interconnections of two or more networks. They forward data packets between networks. They reside at gateways, exactly where two or more networks connects. And they use communication protocols to effectively and efficiently communicate among two or more host.
Answer:
See explaination
Explanation:
//Array to store prices
INT PRICE[10][10]
//Loop through 2d array
FOR I FROM 0 TO 10
FOR J FROM 0 TO 10
//Populate a random int
PRICE[I][J] = RANDOM_INT(99,1999)
PRINT(PRICE[I][J]+" ")
PRINT()
//Prompt user for desired price
COST = READ_INPUT('Please enter your desired flight price: ')
//Variable to store if a match is found
MATCH = FALSE
//Loop through all ints in price
FOR I FROM 0 TO 10
FOR J FROM 0 TO 10
//Compare price with Cost
IF PRICE[I][J]==COST
MATCH = TRUE
BREAK
//Check if match is true
IF MATCH = TRUE
PRINT('A flight was found for that price, have a safe trip!')
ELSE
PRINT('No flight was found for that price, please try a new price.')
Answer:
The answer to this question is given below in the explanation section.
Explanation:
The correct answer to this question is d- 346px.
The complete code of this example is given below:
<div>
style="margin:20px; border:solid 3px #888888;">
</div>
while the image width is 300px.
It is noted that the image width is 300px and the margin is 20 px.
Margin:20px means that image margin from four side is 20 px each.
So the width of dive from both side increase to 40 px and the image has 300 px, then total width becomes 340px. Now the border also has 3px of four sides of the image, then the width of the border becomes 6px.
so the total width of the div tag is 346 px.
In short, we can calculate the width of tag as below:
total width of div= width of image+ width of margin+ width of border
total width of dive= 300px+40px+6px
total width of div=346px.
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
