A broadcast domain is a network segment where data-link layer messages are sent to all devices, while a collision domain refers to the scenario where multiple devices transmit simultaneously, causing packet collisions and requiring retransmission. A network can consist of multiple broadcast domains. Understanding these concepts is essential for managing network traffic and reducing data corruption.

1. Broadcast domain and
Collison domain
Computer network

2. Broadcast
• In this case ,Data-Link layer (Layer 2) message sent to
all devices attached to the same network segment.

3. Collision
• When more than one device transmit data at the same
time on shared media, the packets collide, data becomes
corrupted and after a random period of time, devices
have to re-transmit the data.

4. Broadcast domain
• All devices that a Broadcast messages reaches at the
Data-link layer within a network is called a Broadcast
domain.
• A network can have more than one Broadcast domain.

5. Collison domain
• .
