Show answer & explanation
RJ-45 connectors are used at the ends of Ethernet cables. Key details include:
• Structure: RJ-45 is a larger, standardized 8-pin plastic connector with a locking tab that clicks when inserted, keeping it secure in Ethernet cables.
• Comparison to RJ-11: RJ-45 is larger with 8 pins, used for Ethernet, while RJ-11 is smaller with 4 pins, used for telephones.
• Tip: An RJ-11 phone cable can fit into an RJ-45 port, but not vice versa.
• Usage Context: Used with twisted-pair cables (Cat5e, Cat6) for reliable, high-speed internet up to 100 meters due to twisted pairs reducing interference.
