Answer:
Category 5 (Cat 5) twisted pair is the least quality twisted pair wire that should be used.
Step-by-step explanation:
The reason is as follows:
- Category 1 twisted pair is not suitable for transmitting data but comes in handy for telephone communications. Hence, it should not be used in a data/voice application.
- Category 2 twisted pair is suitable for data transmission, however, it can only transmit at 4Mbps which is very slow. Hence, it should not be used in a data/voice application.
- Category 3 twisted pair can transmit data with speed reaching 10Mbps which is slow for voice/data communication.
- Category 4 twisted pair can transmit data with speed reaching 16Mbps and is used in token ring networks. It is slow for communicating in a voice/data application.
- Category 5 twisted pair is the least qualified to be used in a voice/data application because it can transmit data at speeds that reach 100Mbps.
Hence, Cat 5 or Category 5 twisted pair is the least quality twisted pair that should be used in a data/voice application.
