In which scenario are bridges particularly necessary?

Bridges are particularly necessary in scenarios where there is too much traffic on a Local Area Network (LAN). In environments where a high volume of data is being transmitted, network efficiency can decline due to increased collisions and congestion. Bridges help alleviate this issue by segmenting the network into smaller, more manageable sections or segments.

By dividing the network, bridges reduce the amount of traffic that each device in a segment has to handle. This leads to improved performance, as the data packets only have to be sent to the specific segment where their intended recipients reside, rather than broadcasting to all devices on the network. Thus, implementing bridges can significantly enhance network performance and reduce the likelihood of data packet collisions, providing a more efficient data transmission environment.

In other scenarios like limited network access, providing wireless access, or remote printing, while various network devices and solutions might be required, the primary purpose of bridges is specifically aligned with managing and mitigating network traffic issues.
