<em>One of the features of Operating System is </em><em>it manages and communicates with your system hardware </em><em>by means of Drivers. </em>
<em>Drivers </em><em>are special software within the OS that interacts to the hardware. Drivers uses kernel, a part of the operating system that functions intended to it. For example, when you press Ctrl and P keys on the keyboard, the kernel would recognize this command and would trigger the corresponding hardware in relation to this command. In this case, the corresponding hardware is printer. The kernel would tell the printer to print the document.</em>

Answer: Goal-oriented analysis
Explanation: Goal-oriented analysis is the analyzing activity for focusing on a specific aim or task to be achieved in a desired manner. This analysis requires a high amount of focus , setting the target or goal and the strength and capability to achieve that objective.
Other options are incorrect because sensitivity analysis is analyzing the sensitivity of any task, what-if analysis considers the changing the values of certain function to check the outcome and goal-seeking analysis is analysis in which the output that is to be achieve is already known.
Thus, the correct answer is goal-oriented analysis.
When looking at wireless channels, there are a couple of variables to keep in mind:
The number of other networks using what channels
The strength of the other networks on other channels
So generally speaking, channels 1, 6, and 11 are used by default. The reason for this is because there isn't any adjacent channel interference when you have all of your networks spread out in that manner. If for example, a network was using channel 3, that network would interfere with the signals one channel 1 and 6, and the bandwidth of those channels would have to be shared amongst all of those networks. This isn't optimal. Ideally you should look for a channel with less hosts who have weak signals. I know that in my area, channel 11 is the best channel to be on, because the hosts using that channel have weak signal strengths, which results in a lesser chance of those signals interfering with mine.
