Answer:
The NIC (Network Interface Card) is the computer network component that controls the flow of data between a computer and the network.
Explanation:
The answer is A due to the internet being a plethora of information being accessed by anyone and everyone with internet access. Any person of no background to certain information could claim mastery to the field and sway his/her audience to ways possible. Ensuring that the source of the information being read is from credible and reputable companies. You can do this by ensuring the information is from newspapers with names known all over the world or there are also sourced footnotes from the author where they could have cited some information from other articles.
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
Answer: ....
Dust and debris can cause performance deterioration.
Explanation:
Dust is a problem from the standpoint of blocking fan vents, or, if deep enough, actually insulating parts, causing overheating, but unless it contains substantial amounts of corrosive or conductive material (in which case you shouldn’t be breathing it), it won’t damage the electrical components (beyond any overheating damage).
What could happen, in some circumstances, is condensation inside the box, mixing with dust and creating a conductive sludge. This would generally only occur if you bring the box in from an extremely cold environment (below 0C, roughly) into a humid indoor environment. The protection from this is to wrap the box tightly in plastic before bringing it indoors, and leave it wrapped for a couple of hours, while it has time to warm up.
