Categories of UTP:

These cables have less crosstalk and a better quality signal over longer distances. These cables are mostly suitable for high speed computer communication.

Category	Bandwidth	Data rate	Digital/Analog	Application
1	Very low	<100 kbps	analog	Telephone
2	< 2 Mbps	2Mpbs	Analog/digital	T1 lines
3	16 MHz	10 Mbps	digital	LANs
4	20MHz	20 Mbps	digital	LANs
5	100MHz	100Mbps	digital	LANs
6	200MHz	200Mbps	digital	LANs
7	600MHz	600Mbps	digital	LANs

Twisted pair cables

Twisting of wires will reduce the effect of noise or external interference.

Number of twists per unit length will determine the quality of cable. More twists means better quality.
