What are two consequences of having all network devices in a single collision domain?

Acollision domainis a network segment where data packets can "collide" with one another when being sent on the same network medium.

Step-by-Step Breakdown:

Increased Collision Probability:If all devices are in asingle collision domain, the likelihood of packet collisions increases as more devices attempt to send packets simultaneously, leading to network inefficiencies.

Increased Resource Consumption:More collisions result inincreased network resource consumptionas devices need to retransmit packets, causing higher utilization of bandwidth and slowing down network performance.

Juniper Reference:

Collision Domains: Proper network segmentation using switches reduces collision domains, thereby improving network performance and reducing packet collisions.
