A Cat 5(good) or Cat 6 (better) ethernet cable plugs into the router and the ethernet slot in the back of the PS3 for a wired internet connection.
Cat 5 is a type or standard of ethernet cable (350 Mhz) and is not as good as the Cat 6 (500+Mhz) which will work wherever you were going to use the Cat 5 ethernet cable and not require replacement as cable/DSL broadband internet speeds increase
The better microphones use XLR-plugs as connection.
To terminate a Cat 5 cable properly, you will need to strip the outer jacket, separate and arrange the individual wires according to the T568A or T568B wiring standard, trim the excess wire length, and insert the wires into a modular connector. Finally, use a crimping tool to secure the wires in place.
Typically you would use a CAT-5e or CAT-6 UTP (Unshielded Twisted Pair) network cable.
You use a cable that usually come with your phone, and the cable plugs into your phone and your computers USB port.
The modern Ethernet cable is a Category 5 UTP cable, with an RJ 45 connector.
If you can use fiber optics. If not try to use CAT-5e at least, CAT-6 is recommended.
Most LANs use UTP cable, category 5 or better.
Cat 6
Use a CAT-5, also known as an Ethernet cable.
A regular Cat 5e or Cat 6 RJ-45 straight-through Ethernet network cable.
