Question

2 the text draws contrasts between wired networks and wi - fi. one difference is that wi - fi doesnt need to be attached to a cable, and wired networks do. what is another difference described in the text? a wi - fi converts information into 0s and 1s and wired networks convert information into 2s and 5s. b wi - fi uses radio waves and wired networks use electrical impulses. c wi - fi uses two types of ethernet cables and wired networks do not use ethernet cables at all. d wi - fi has five frequencies and wired networks have two frequencies.

Explanation:

Wi - Fi uses radio waves for communication while wired networks typically use electrical impulses through cables. Option A is incorrect as both Wi - Fi and wired networks convert information into 0s and 1s. Option C is wrong because Wi - Fi does not use Ethernet cables. Option D is inaccurate as there is no such standard frequency difference as described.

Answer:

B. Wi - Fi uses radio waves and wired networks use electrical impulses.
