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.
I believe the answer is true
Answer:
The problem with Paul's computer is that the magnetic hard drive failed.
Explanation:
A magnetic hard drive or hard disk is a non-volatile storage device, which is used to store different information on a computer.
The magnetic disk is made up of numerous magnetic plates, these plates are divided into sectors and tracks. A spindle is present in the middle to rotate the combined plates or the whole unit.
When there is a clicking noise coming from the magnetic disk, it could mean that one of the plates is damaged or if the power to the computer is inconsistent. This can greatly affect the performance of your computer.
