B1 and 3

C2, 3 and 4

D1 and 2

Correct answer: (A) 1, 2 and 4

Explanation

On networked computers users can communicate by email and instant messenger, share files easily and share one printer.

Statement 1 is true because a network carries email and instant messages between connected users.

Statement 2 is true because files placed on the network can be opened by other permitted users.

Statement 4 is true because a single shared printer can serve many users on the network.

Statement 3 is false, since a network can actually help viruses spread faster from one machine to others.

This is why shared networks need firewalls and antivirus protection on every connected computer.
