Explain the difference between Collision Domain and Broadcast Domain.
Broadcast Domain :
 
* In the Broadcast Domain, all the juncture can reach each other by broadcast at the Data Link Layer and every device is ready to receive their respective data. It can bind to the same LAN segments or the other LAN segment.
 
* Broadcast Domain uses a local network for broadcasting the data packets to the receiver. While broadcasting, massive data are broadcasted, hence the speed of receiving the data is less and it also takes more time to receive the data of their address.
 

Collision Domain :
 
* In the Collision Domain, data collision occurs more due to the sending of more frames simultaneously.
 
* If more than two frames are sent simultaneously then the data will collide with each other in between and the information gets lost. Hence, the devices will not accept the data and due to this, the communication between the sender and receiver side will collide.
 
* Thus, the sender has to send the data again and like this, it will take more time to receive the data at the receiver’s side.
