There are different categories in cabling and they are depicted by their bandwidth and there are two key varieties, UTP (unshielded twisted pair) or STP (Shielded twisted pair).
Cat3 or category 3 network cables or station wire/VG Voice-grade unshielded twisted pair cables used for telephone wiring. This cable carries up to 10 Mbps (1.2 MB / s i.e 1 hour to download a DVD (4.5 GB)), but most modern networks run at much higher speeds. Cat3 cabling is still used in two-line phone configurations. Cat3 cable relies on copper for data and power transmission.
