Explanation

Each security term matches the description of what it does on a computer or network.

Cookies pair with small files stored on a user's computer to remember their preferences across website visits.

Encryption pairs with the process that makes data appear meaningless without the correct unlocking key.

Firewall pairs with hardware and software between a computer and an external network that filters data flowing in and out.

Spam pairs with unsolicited emails sent to recipients on a mailing list that clog up the inbox.

Together these represent common privacy and security concepts in everyday computing.
