Question:
Which of the following is an eight-pin connector that is used exclusively with ethernet cables for networking?
Which of the following is an eight-pin connector that is used exclusively with ethernet cables for networking?
Show Hint
Do not confuse RJ11 with RJ45:
- RJ11 has 4 or 6 pins and is used for telephone lines.
- RJ45 has 8 pins and is used exclusively for Ethernet computer networks.

- RJ45
- Switch
- Router
- Repeater

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Identifying Physical Network Interfacing Standards:
Wired network cabling requires standardized modular connectors to establish physical connections with the network interface cards (NICs) on devices.
Step 2: Analyzing the Options:
- Switch (B), Router (C), Repeater (D): These are active networking devices, not physical modular connectors.
- RJ45 (Registered Jack 45) (A): A standardized physical connector plug containing 8 pins (positions) and 8 metal contacts (8P8C configuration). It is used exclusively on the ends of twisted-pair copper ethernet cables (such as Cat5e, Cat6, or Cat6a) to connect network nodes to wall jacks, switches, or routers.
Step 3: Conclusion:
Therefore, the eight-pin connector used with ethernet networking cables is the RJ45 plug (A).
