Over a TCP connection, suppose host A sends two segments to host B, host B sends an acknowledgement for each segment, the first acknowledgement is lost, but the second acknowledgement arrives before the timer for the first segment expires is True.
True
<u>Explanation:</u>
In network packet loss is considered as connectivity loss. In this scenario host A send two segment to host B and acknowledgement from host B Is awaiting at host A.
Since first acknowledgement is lost it is marked as packet lost. Since in network packet waiting for acknowledgement is keep continues process and waiting or trying to accept acknowledgement for certain period of time, once period limits cross then it is declared as packet loss.
Meanwhile second comes acknowledged is success. For end user assumes second segments comes first before first segment. But any how first segment expires.
Answer:
public class ForLoops {
public static void main (String [] args) {
int countNum;
int i;
countNum = 3;
System.out.println("Ready!");
for(i = countNum;i>0;i--) {
System.out.println(i);
}
System.out.println("Go!");
}
}
Output:
A model which allow designers to use a graphical tool to examine structures rather than describe them by using text is called entity relationship.
<h3>What is an
entity relationship?</h3>
An entity relationship can be defined as a data model with the highest level of abstraction and it is designed and develop to avail designers an ability to use a graphical tool to examine structures rather than describe them by using text.
This ultimately implies that, an entity relationship can be used to label the various relationship types based on connectivity, especially through the use of a graphical tool to examine structures rather than describe them with text.

Answer:
option C
Explanation:
The correct answer is option C
the uploaded image shape is ( 433 , 650 )
this shape means that the image is a grayscale image which is 433 pixels high by 650 pixels wide.
a gray scale image is in white and black color.
433 pixels high by 650 pixel wide means that the image is formed with the combination of 433 vertical dots and 650 horizontal dots.
Resolution of an image can be found out by the pixels present in the images.
higher the pixel higher is he resolution of the image.
