Which field in a transmission control protocol (tcp) header is chosen from ephemeral ports?

The field in a Transmission Control Protocol (TCP) header that provides the next expected segment is; acknowledgement number

The different fields in Transmission Control Protocol (TCP) Segment Header include;

Among these 9 fields, the only one that provides the next expected segment is called Acknowledgement number. This is because acknowledgement number is simply defined as the sequence number of the next byte that the receiver expects to receive and as such it provides the next expected segment.

The Field in the header that will helps keep track of the many segments is the : Sequence number

Hello the options related to your question is missing but the correct answer have been provided above

The sequence number in a Transmission control protocol ( TCP ) helps keep count of the number of byte been sent out by a host.  The sequence number is also a TCP segment, because the sequence number increases in proportion to the number of bytes contained in the TCP packet.

Hence we can conclude that the Field in the header that helps keep track of the many segments is the sequence number

True, a retractable service pit cover can help other shop employees from falling into the pit while another technician is in the pit servicing a car.

Retractable service pit cover is a special cover made to cover service pit which aid inspection and repair of vehicle in an auto workshop.

In conclusion, the retractable service pit cover help other shop employees from falling into the pit even if they are aware of the structure.

Code:

#include <iostream>

using namespace std;

int main()

{

  int Car_Year;

  cout<<"Please Enter the Car Model."<<endl;

  cin>>Car_Year;    

 if (Car_Year<1967)

 {

cout<<"Few safety features."<<endl;

 }

else if (Car_Year>1971 && Car_Year<=1991)

{

cout<<"Probably has head rests."<<endl;

}

else if (Car_Year>1991 && Car_Year<=2000)

{

cout<<"Probably has antilock brakes."<<endl;

}

else if (Car_Year>2000)

{

cout<<"Probably has airbags."<<endl;

  }

else

{

cout<<"Invalid Selection."<<endl;

}

  return 0;

}

Output:

Please Enter the Car Model.

1975

Probably has head rests.

Please Enter the Car Model.

1999

Probably has antilock brakes.

Please Enter the Car Model.

2005

Probably has airbags.

Please Enter the Car Model.

1955

Few safety features.

Explanation:

We were required to implement multiple If else conditions to assign car model year with the corresponding features of the car.

The code is tested with a wide range of inputs and it returned the same results as it was asked in the question.

"Test Phase " is the correct choice.

Explanation:

NTQ

Explanation:

The given sequence is

BHE : FLI : JPM

If is clear that, alphabets on first places are B, F, J. Difference between their place vales is 4.

B+4=F,F+4=J ; so alphabet on first place of next term of sequence is J+4=N.

Similarly, alphabets on second places are H, L, P. Difference between their place vales is 4.

H+4=L,L+4=P ; so alphabet on second place of next term of sequence is P+4=T.

Alphabets on third places are E, I, M. Difference between their place vales is 4.

E+4=I,I+4=M ; so alphabet on third place of next term of sequence is M+4=Q.

Therefore, the next term is NTQ.
