Small data sets that are easy to manage and analyze.
Data that is only relevant to small businesses.
Data that is outdated and no longer useful.
What is a digital signature?
A method to encrypt data for security purposes.
A cryptographic method to verify the authenticity and integrity of a message or document.
A type of electronic payment system.

What is a cipher text?
Data that has been encrypted and is unreadable without the correct decryption key.
Plain text that can be easily read by anyone.
A type of software used for encryption.
A method of data compression.
What is a hash value?
A fixed-size string produced by a hashing algorithm to uniquely represent data.
A variable-length string used for data encryption.
