What is encryption used for?

• A. To speed up data transmission
• B. To convert data into a code for security
• C. To store data more efficiently
• D. To reduce the size of files

Answer: (B)

Encryption is used primarily to convert data into a code for security purposes. This process involves transforming readable data, known as plaintext, into an unreadable format called ciphertext using algorithms and keys. The primary goal of encryption is to protect the confidentiality and integrity of data, ensuring that even if an unauthorized individual gains access to the encrypted data, they cannot understand or use it without the decryption key. This is crucial in various contexts, such as securing communications over the internet, safeguarding sensitive information in databases, and maintaining privacy in financial transactions. While encryption does not inherently speed up data transmission, improve storage efficiency, or reduce file sizes, its main function is to maintain the security and privacy of data during storage and transmission.
