What’s the difference between RJ45 and CAT5? Can the one be converted to the other?

Answer 1

RJ45 is the standard for the connection itself, and the CAT designation is typically for the speeds attained via that interconnection.

The RJ45 standard is an expansion from the RJ11 (telephone line) and it details four twisted pairs of wires connected by the RJ45 connector. The CAT standard details the speeds attained via the RJ45 on a specific protocol.
