Answer:
All the ports in a hub are in the same collision domain and a hub sends frames from one host to all other hosts in the network. This makes it prone to collision and poor network throughput. Just like a network switch, it uses the CSMA/CD protocol to detect collision in its network.
A network switch reduces its collision domain to just a port and sends frames from one host to another using its mac table as a route. This makes the network very efficient with high throughput. It also uses the CSMA/CD protocol to detect collision
Explanation:
Switches and hubs are used in networking to connect computer devices in a network. A hub is an obsolete device networking that broadcast a frame to all other ports or host in the network except for the send host port. This increases the rate of collision as all the ports in a hub share the same collision domain. A switch is an efficient frame switching device in a network, which uses its MAC table to decide and find a destination host.
CSMA/CD is a collision detection protocol used in a network to detect and prevent a collision. With this protocol, a host is able to listen, wait, send and resend frames to prevent a collision.
Answer:
A loop in a computer program is an instruction that repeats until a specified condition is reached. In a loop structure, the loop asks a question. If the answer requires action, it is executed. ... A computer programmer who needs to use the same lines of code many times in a program can use a loop to save time

The correct sequence is as shown above.
Answer:
Following show the trace table.
Explanation:
a)
int i = 0; int j = 10; int n = 0;
while (i < j) { i++; j--; n++;
}
i j n
1 9 1

3 7 3
4 6 4
5 5 5
b)
int i = 0; int j = 0; int n = 0;
while (i < 10) { i++; n = n + i + j; j++;
}
i j n
