Answer - In this present age, CAN bus wiring helps in order to maintain a precise communication between two dedicated wires. Differential signals are much more influenced by the high voltage wiring, several inductive loads and many more aspects in a significant way.

9.1) What is twisted pair wiring? Answer in 20 – 50 words

Answer - Twisted pair helps in order to maintain communication between the home as well as a business computer in the telecom industry in a precise manner.

9.2) List five (5) benefits of using it.

Answer - In this regard, there are several benefits to this Twisted pair. These are such as-

? The context of the twisted pair helps to carry both digital and analogue data as well.
? It is very easy in order to create as well as terminate.
? If there is any kind of distraction in the twisted pair, it can not harm the overall network.
? It is not so expensive in order to implement and also it maintains the transmission in a short distance.
? It can access the highest efficiency in the whole network system which is reflected in the work criteria as well.

10) What is shielded wiring and why do you use it? Answer in 20 – 50 words.

Answer - Shielded wiring is a significant process of wiring that is reflected in the protection of several pieces of equipment from the effect of an electrostatic field that is completely external to the parts as well. Basically, it has been observed that shielded wiring helps in order to maintain and protect the power as well as the data path from the effect of degradation that is also caused by the exposure of EMI during the transfer of data and power as well.

11) Explain how you access the electrical terminals on a vehicle with test probes using a method that will ensure you are not doing any damage to connectors, fuse holders and wires. Answer in 20 – 50 words.

Answer - In this aspect, there are the following steps in order to maintain the aspect of the process.
