The Correct Option is C
Solution and Explanation
Concept:
Twisted-pair Ethernet cables (such as Cat 5e and Cat 6) use standard modular connectors to plug into Network Interface Cards (NICs), switches, and routers.
Step 1: Standard Definition:
The acronym RJ stands for Registered Jack.
A Registered Jack is a standardized telecommunication network interface for connecting voice and data equipment to local networks or public telephone systems.
Step 2: Characteristics of RJ-45:
The RJ-45 connector features an 8-position, 8-contact (8P8C) modular configuration.
It is the standard physical connector used for terminating twisted-pair Ethernet cables in local area computer networking.
Final Answer:
"RJ" stands for Registered Jack, making option (C) the correct choice.
