How does switching help mitigate collisions in Ethernet networks?

• A. By increasing the bandwidth
• B. By creating separate collision domains
• C. By enabling wireless connections
• D. By reducing the number of devices

Answer: (B)

In Ethernet networks, switching helps mitigate collisions primarily by creating separate collision domains. Each port on a switch represents an individual collision domain. This means that when devices connect to the switch, they can communicate without interfering with one another, significantly reducing the chances of collisions that are common in shared environments. In a shared Ethernet environment, multiple devices share the same bandwidth and must contend for access to the network. When devices attempt to transmit simultaneously, a collision occurs, leading to data loss and the need for retransmissions, which can degrade performance. However, when a switch is employed, each device connected to it operates within its own collision domain. Therefore, devices can send and receive data concurrently without causing collisions, as each port on the switch manages its own traffic independently. This architecture allows for more efficient data transmission and overall better performance within the network. The process effectively isolates traffic and prevents the congestion that results from collision-prone communications, resulting in a more reliable and faster Ethernet network.
