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: Protocol
Explanation: Protocol is the standard that is used in the communication and electronic devices for the communication. Through the mean of the these guidelines the communication is done by the sending and receiving of the data.
This works for the both wired networking and wireless communication which functions under the certain conditions.Examples-TCP(Transmission control protocol), FTP(File transfer protocol) etc.
