非屏蔽双绞线 (UTP) 和屏蔽双绞线 (STP) 电缆之间的区别

UTP：
UTP 是一种双绞线电缆。它代表非屏蔽双绞线。数据和语音都通过UTP传输，因为它的频率范围合适。在 UTP 中不需要接地电缆，在 UTP 中也不需要更多的维护，因此它具有成本效益。

直通车：
STP 也是双绞线的一种，代表屏蔽双绞线。在 STP 中需要接地电缆，但在 UTP 中不需要接地电缆。在屏蔽双绞线 (STP) 中需要更多的维护，因此它比非屏蔽双绞线 (UTP) 成本更高。

非屏蔽双绞线 (UTP) 和屏蔽双绞线 (STP) 电缆的区别：

S.NO	UTP	STP
1.	UTP stands for Unshielded twisted pair.	STP stands for Shielded twisted pair.
2.	In UTP grounding cable is not necessary.	While in STP grounding cable is required.
3.	Data rate in UTP is slow compared to STP.	Data rate in STP is high.
4.	The cost of UTP is less.	While STP is costlier than UTP.
5.	In UTP much more maintenance are not needed.	While in STP much more maintenance are needed.
6.	In UTP noise is high compared to STP.	While in STP noise is less.
7.	In UTP the generation of crosstalk is also high compared to STP.	While in STP generation of crosstalk is also less.
8.	In UTP, attenuation is high in comparison to STP.	While in STP attenuation is low.
