Answer to Question 1

Answer: C
Explanation: C) The potential drawbacks of IM include security problems (computer viruses, network infiltration, and the possibility that sensitive messages might be intercepted by outsiders), the need for user authentication (making sure that online correspondents are really who they appear to be), the challenge of logging messages for later review and archiving (a legal requirement in some industries), incompatibility between competing IM systems, and spim (unsolicited commercial messages, similar to email spam).

Answer to Question 2

Answer: B
Explanation: B) The benefits of IM include its capability for rapid response to urgent messages, lower cost than phone calls and email, ability to mimic conversation more closely than email, and availability on a wide range of devices. In addition, because it more closely resembles one-on-one conversation, IM doesn't get misused as a one-to-many broadcast method as often as email does.
