Final answer:
The term 'cross-connect input port' is not standard in networking, but if the question refers to using crossover cables, older devices might require them for direct connection. However, modern devices typically use auto-MDI/MDIX, which removes the need for crossover cables. Routers, hubs, switches, and repeaters usually do not have a specific 'cross-connect input port'.
Step-by-step explanation:
Which Devices Require a Cross-Connect Input Port?
The question appears to have a typo or confusion in terms, as 'cross-connect input port' is not a standard term for describing ports on networking devices. For most networking equipment, cross-connects refer generally to the use of patch panels and cables in a structured cabling system to connect different devices. However, the devices listed mainly utilize standard ports for network communication. Here is a clarification for each device mentioned:
- Routers: These typically use Ethernet, serial, or other types of ports for connecting to networks. They route packets between different networks.
- Hubs: Now largely obsolete, hubs do not require special input ports. They simple forward incoming packets out all other ports.
- Switches: Similar to routers, switches use standard network ports (usually Ethernet) and facilitate the flow of data within the same network.
- Repeaters: These simply regenerate and amplify signals in a network and also do not have a specific 'cross-connect input port'.
The term 'cross-connect input port' might be a source of confusion, perhaps the student is referring to the need for crossover cables that were once needed to connect similar devices directly (e.g., switch to switch), but with modern devices, this is often no longer necessary due to the implementation of auto-MDI/MDIX.
