Under the specification of the ieee 802.11g standard, an acknowledgementmust be returned within a particular amount of time, say, x microseconds. why is it important to specify x instead of saying something like ``the receivershould return an ack as quickly as possible''?

answer is:

a). backstage view

explanation:

backstage view is the area where files and data about them is managed— creating, saving, printing, sending to others, inspecting for hidden metadata or personal information, and setting options. so in this way we can add many things to our document swiftly.

i hope you get the idea.

make sure each item is its own paragraph.
