A collision domain consists of all the clients that could possibly cause a collision amongst themselves by sending a packet at the same time. Devices such as hubs create a single collision domain which means that everyone connected to the hub has the capability of causing a collision (which is a problem).
A broadcast domain consists of all the clients that can receive the same broadcast packet. Unlike a collision domain this is not a problem. Think of it as those systems that are capable of receiving the broadcast message.
What else can I help you with?
How many collision and broadcast domain are there if a router is directly connected to hub?
A hub contains a single collision domain and a single broadcast domain, regardless of the number of ports on the hub.
Are devices in a single collision domain in the same broadcast domain?
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.
Can the router break up collision domain?
Yes, routers can break up collision and broadcast domains.
How many collision domain in a hub?
Hubs are not collision domains but a networking device. Hubs have single collision domain that makes them very undesirable for modern networks.
Is bridge a collision domain?
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.
What is Another way to describe a collision domain is?
Ethernet segment.
What breaks up collision domains and broadcast domains?
On shared-media networks (i.e. hubs or pure ethernets), routers break up broadcast domains and bridges break up collision domains. Routers also break up collision domains. On switched networks, routers break up broadcast domains, and every switch port is its own separate collision domain.
Is a VLAN essentially a collision domain?
No- A VLAN is a single broadcast domain. If the VLAN uses a hub, which essentially connects all devices on a single wire, the the VlAN would be a collision domain. However hubs are rarely seen these days. A network switch keeps every device separated on individual collision domains so every device is kept from colliding with any other device.
How many broadcast domain are created when you segment a network with 12-port switch?
Zero. No collisions can occur within a full-duplex environment, as transmit and receive operations are performed on another set of wires. Thus, no collision domains would exist. Carrier Sense Multiple Access with Collision Detection (CSMA/DC) is not part of a full-duplex network for this reason.
What devices can you use to limit the size of a 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.
What is a single collison domain?
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. ----
How many collision domains and broadcast domains are there in the given network topology?
To determine the number of collision and broadcast domains in a network topology, one must analyze the devices involved. Each switch creates separate collision domains for each connected device, while a router or Layer 3 switch creates separate broadcast domains. Without a specific topology diagram or description, it's impossible to provide an exact count; however, generally, each switch adds collision domains, and each VLAN or router adds a broadcast domain.
