Dear Akash,

Collision domain: L1 Frames would collide between others (hubs, access points, repeaters, bridges) and only one device can send and receive at the same time.

Broadcast domain: L2 Broadcast frame sent to all devices on the network and all those devices can receive it in the same time (switches), The switch creates an entire broadcast domain, but every one of its ports creates a single collision domain.
