A bridge typically creates separate collision domains within the same broadcast domain. If you take a bridge with 2 ports, each port connects to a LAN segment that is in its own collision domain.
Therefore, for a 2 port bridge you will get 2 different collision domains.
In the olden days you would use a bridge because hubs were one collision domain. The bridge was basically an expensive switch. Today on switches each switch port is on its own collision domain.

A switch or router will limit the number of clients in a collision domain, thus limiting what can be in the collision domain.
A hub contains a single collision domain and a single broadcast domain, regardless of the number of ports on the hub.
A collision domain is an area on the network where two devices may attempt to transmit at the same time. A hub has 1 collision domain overall. A switch has 1 collision domain per interface. The fewer devices in 1 collision domain, the better. ----
AnswerYes. You can't split a broadcast domain without also splitting the collision domain. The only devices that can split a broadcast domain are routers and layer 3 switches. Switches, bridges, and routers can all be used to split the collision domain. Hubs and repeaters do not split the collision domain or the broadcast domain.
Hubs do not reduce collision domains. All devices connected to the hub are in a single collision domain, where as on a switch, each port is its own collision domain.
in my opinion there is no any collision domain in the router......but switch has collision domains for each interfaces & hub has one collision domain
