Hubs are very simple devices that connect network components, sending a packet of data to all other connected devices.
Hubs are relatively basic network connectors that send a packet of data to every other connected device. Compared to a hub, a switch is more intelligent and has the ability to filter and forward data to a specific location. Within various networks, switches are utilized. Nodes of the network are any computers or printers connected to it. A network workstation is a personal computer that is linked to a network (note that this is different form the usage of the term workstation as a high-end microcomputer). Nodes of the network are any computers or printers connected to it. A network workstation is a personal computer that is linked to a network.

Answer: B. hummer
Explanation:
Given the array :
Given the arra
("explorer", "testa", "hummer", "corvette", "civic", "mustang")
Array indexing usually begins from 0
That is ; the first element in the array is indexed as being in position 0
Using the given array as an example :
Index ____ element
0 ______ explorer
1 _______ tester
2 _______hummer
3 _______ corvette
4 _______ civic
5 _______ mustang
Hence, element in index 2 of the array is hummer
Answer:
1. Hydrostatic pressure.
2. Pressure.
3. Equilibrium forces.
Explanation:
1. <u>Hydrostatic pressure</u>: pressure exerted by a stationary liquid. It is simply the pressure in a liquid such as water at a specific depth.
Mathematically, hydrostatic pressure is given by the formula;

Where:
- H.P is the hydrostatic pressure of a liquid.
- rho represents the density of a liquid.
- g is the acceleration due to gravity.
- d is the depth (height) of a liquid.
2. <u>Pressure</u>: it is the force in a direction perpendicular to a given surface area. Thus, it's typically measured in Newton per meters (N/m²).
Mathematically, pressure is given by the formula;

3. <u>Equilibrium forces</u>: a pair of forces whose resultant is zero. It is also referred to as balanced forces because the resultant of all the pair of forces acting on a body or system is at equilibrium (balanced).
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
