Answer:
a: Twisted pair won't span a 400-foot distance.
Explanation:
The maximum distance that twisted pair cables can support without attenuation is 100 meters which is approximately 328 feet and the two office buildings are 400 feet apart, so it is useless to install a twisted pair cable for such a large distance. A much better option would be to install optic fiber. Though it is a bit expensive but it is the best option in this case.
Hence option (a) is the correct reason for installing an optic fiber cable rather than a twisted pair cable.
It is targeted at one person specifically. More work for the attacker, but higher chances of obtaining sensitive information.
Answer:
Let's take an example of the embedded system, which is a perfect example of this question as a computer system. Suppose we want the embedded system to record the details related to soil of agricultural land. We will take an IoT device which will be a sensor that can register soil properties, and get connected to the computer system through the internet. And we design an embedded system that registers these values and then copy them like somewhere in DB space on Amazon cloud or Google cloud. And finally display on some LCD or a big projector, or whatever, and like we design. Thus we have designed, and now when we install this on agriculture land, we implement it, and since check regular for correct performance, we maintain this embedded or a mini-computer system as well. This is what design, implement and maintain computer systems mean.

Answer:
Gradient, in mathematics, a differential operator applied to a three-dimensional vector-valued function to yield a vector whose three components are the partial derivatives of the function with respect to its three variables. The symbol for gradient is ∇.
