1.	What do you mean by a broadcast domain and a collision domain?
Answer» Broadcast Domain: As the NAME suggests, a Broadcast domain is a logical set of reachable computer systems without having a router. In this TYPE of domain, traffic flows all over the network. In this scenario, when a device sends a broadcast message, then all the other devices present in its broadcast domain have to pay attention to it. Collision Domain: As the name suggests, a Collision domain is a part of a network where PACKET collisions can take place when being sent on a shared medium or through REPEATERS. In this scenario, when a device sends a message to a network, then all other devices present in its collision domain have to pay attention to it, whether or not it was destined for them.
