What happens when two devices on a shared network segment send packets simultaneously?
What happens when two devices on a shared network segment send packets simultaneously?
- The packets are prioritized based on IP addresses
- The packets collide and must be sent again (correct)
- The packets merge into one and reach the destination twice as fast
- The packets are discarded if they are not encrypted
In which type of network device do all ports belong to the same collision domain?
In which type of network device do all ports belong to the same collision domain?
- Router
- Bridge
- Switch
- Hub (correct)
How does a bridge, switch, or router differ from a hub in terms of collision domains?
How does a bridge, switch, or router differ from a hub in terms of collision domains?
- They create virtual collision domains
- There are no collision domains in these devices
- All ports share the same collision domain
- Each port is in a separate collision domain (correct)
