Normally workstations don't share collision domains on switches today. Each switch port is a collision domain. Back in the olden days you would use a hub. It would just repeat the electrical signals on all ports. If two PCs share the same physical media (e.g. same wire/ hub) they are in the same collision domain. A good example would be Wi-Fi. All participants have to share the same electromagnetic media; they take turns. For more information on how collisions are resolved, check out the CSMA/CD and CSMA/CA protocols.
two computers connected to the same hub AND two computers connected to the same access server
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
Collision domain
A layer 1 device will extend a collision domain
You can't eliminate collision in a broadcasting domain. What you can do is to increase the number of collision domain within a broadcasting domain by using more switches. this will improve your network traffic because the more the collision domain, the better is your network in terms of data transmission performance.
A hub has a single collision domain, which is why it can cause problems when network traffic is high.
Hubs are not collision domains but a networking device. Hubs have single collision domain that makes them very undesirable for modern networks.
