How many collision domains are shown in the following diagram?
In the given diagram, there are a total of four collision domains. Collision domains are areas within a network where network devices can potentially interfere with each other’s data transmission, leading to collisions. Understanding the number of collision domains in a network is crucial for network design and troubleshooting, as it helps in determining the efficiency and performance of the network.
The diagram consists of four distinct collision domains, each separated by a router. A router is a networking device that connects multiple networks and is capable of forwarding data packets between them. The separation of collision domains by routers ensures that devices within each domain can communicate without interference from devices in other domains.
The first collision domain is represented by the first two computers connected to a switch. Switches are networking devices that forward data packets only to the port where the destination device is connected, reducing the chances of collisions. The second collision domain includes the third computer connected to the same switch, while the fourth collision domain encompasses the last two computers connected to a different switch.
The second and third collision domains are separated by a router, which connects the two switches. This router acts as a gateway for the devices in the second and third collision domains, allowing them to communicate with each other. The fourth collision domain is isolated from the other three, as it is connected to a different switch and router.
In conclusion, the diagram illustrates four distinct collision domains, each separated by routers or switches. Recognizing the number of collision domains in a network is essential for ensuring optimal network performance and efficient data transmission.
