In step 4 of the CSMA/CA protocol, a station that successfully transmits a frame begins the protocol to transmit a second frame

at step 2, rather than step 1.What rationale could justify this procedure over simply transmitting the second frame immediately (if the channel is sensed idle)?

Answer:

Using CSMA/CD to avoid collision.

Explanation:

If the channel is detected idle then the station does not transfer the second frame to avoid the collision by design of the CSMA/CD (Carrier sense multiple access / Collision detection). When received the protocol for first frame, a station to send second frame begins at step 2 rather than step1.

Explanation :

• Station A and Station B are transfers data frames, remain all not want to transmit data. In this situation, station A find the channel to be idle and send first frame then next second frame.  

• Similarly B received the transfer data at the same time. Then leads to collision.  

• Using CSMA/CD to avoid collision.

torisob [31]

Explanation:

public class Int_List

{

protected int[] list;

protected int numEle = 0;

 

public Int_List( int size )

{

list = new int[size];

public void add( int value )

{

if ( numEle == list.length )

{

System.out.println( "List is full" );

}

else

{

list[numEle] = value;

numEle++;

}

}

public String toString()

{

String returnStr = "";

for ( int x = 0; x < numEle; x++ )

{

returnStr += x + ": " + list[x] + "\n";

}

return returnStr;

}

}

public class Run_List_Test

{

public static void main( String[] args )

{

 

Int_List myList = new Int_List( 7 );

myList.add( 102 );

myList.add( 51 );

myList.add( 202 );

myList.add( 27 );

System.out.println( myList );

}

}

Answer:

Use the System Restore tool to restore the affected computers back to a point before the problematic updates. To forestall issues with problematic updates, one needs to install and configure the Windows Server Update Services (WSUS) Server role.

Explanation:

Windows Update creates a restore point prior to applying any updates and this makes it easier to rollback any problematic updates using the aptly named System Restore utility.  System Restore can be launched either from within Windows or during startup depending on whether the computer can be booted  or not.

One solution to preventing this kind of problem is the implementation of a Windows Server role, the Windows Server Update Services (WSUS), which helps administrators to safely manage Windows Update for clients within its network. WSUS allows administrators to test updates for issues and approve them before they are available for deployment to clients.

¿Cuál es la potencia de una lámpara de incandescencia que se conecta a la red de 220 V, sabiendo que tiene una resistencia de 50
Juliette [100K]

Answer:

  • <u>1,000W</u> (rounded to one significant figure)

Explanation:

I will answer in English.

The question is:

  • <em>What is the power of a filament lamp that connects to the 220 V network, knowing that it has a resistance of 50 ohms?</em>

<em />

<h2>Solution</h2>

<em />

<em>Power</em>, <em>voltage</em>, <em>resistance</em>, and current, are related by either of the following equations:

  • P = V × I
  • P = R × I²
  • P = V² / R

Where:

  • P is power in watts (W)
  • R is resistance in ohms (Ω)
  • V is voltage in volts (V), and
  • I is current in amperes (A)

Since you know the voltage (<em>220V</em>) and the resistance (<em>50Ω</em>), you can use the last equation:

  • P = V² / R
  • P = (220v)² / (50Ω)
  • P = 968 W

Since the magnitude 50Ω has one significant figure, your answer should be rounded to one significant figure. That is <u>1,000W.</u>

What does the following code alert?
goldenfox [79]

It is just a declaration of an object variable, <em>person</em>, in JavaScript. Within a <em>person</em> object, there are key:value pairs. The code that you  shared has the following keys: name, age, and favouriteFood, whereas the values of those keys are: Mike, 25, and pizza.


There is <em>no</em> alert statement in this code snippet; therefore, it <em>will not alert </em>anything. This code contains only a variable called <em>person, </em>and that's it!
