Select the true statement about network protocols.
Computers that are distributed across a large geographic area need a special protocol to
resolve errors.
One function of a protocol is to decompress data when it is delivered to the
receiving computer.
Using a protocol other than TCP/IP can result in data loss.
Communication cannot take place unless the protocol is executed in the same way on all
devices.
RATIONALE
A protocol is a system of rules that enables two or more entities (computer devices) in a
communications system to send and receive information. Communication cannot take
place unless the protocol is executed in exactly the same way on all devices.

David’s computer is infected with spyware.
What problem can David expect as a result?
His computer will be infected by a virus that could delete his files.
Hackers will steal his files through pop-up windows.
The malware will install a toolbar that redirects his web browser.
Information about his computer usage will be sent to an outside party.
RATIONALE
Spyware is a security risk because it usually compromises data confidentiality. David should
be concerned that information about his computer usage will be sent to an outside party.
