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.

What will the following code display? #include using namespace std; void doSomething(int); int main() { int x{2}; cout &lt;&lt;
Leno4ka [110]

Answer:

The code will display the following on the screen:-

2

0

2

Explanation:

The output is like this because x{2} assigns the value 2 to the integer x.First the value of x is printed on the screen that is 2 and that newline is used to go to the next line.After that function is called doSomething with x passed as the argument. doSomething function assigns the value zero to the variable passed and prints it on the screen.So the next line is 0.Since x is passed by value so no changes will appear in the original argument.Hence the last line printed is 2.
