Broward College Computer Literacy Practice Test

Encryption is best described as which of the following?

A process that converts data into unreadable format unless you have a key to decrypt it. A process that compresses data to save space. A way to speed up network connections. A security protocol for remote desktops.

Correct Answer:

A process that compresses data to save space.

Explanation:

Encryption is a method that transforms readable data into an unreadable form that can only be restored with the correct decryption key. This protects the information so that even if someone intercepts it, they can’t read it without the key. It’s not about making files smaller—that would be compression. It doesn’t inherently speed up networks, and it’s not a specific security protocol for remote desktops. So the best description is: data is turned into unreadable format unless you have the decryption key.
