Data Types and Encryption Concepts Quiz

What is a non-composite data type?

• A data type that can hold multiple values of different types

• A data type that holds a single value

• A data type that is used for file organization

• A data type that is used for encryption

Which of the following is a composite data type?

• Integer

• Array

• Boolean

• Character

What is the main characteristic of serial file organization?

• Records are stored in a specific order

• Records are stored in the order they are received

• Records are stored based on a key field

• Records are stored randomly

In sequential file access, how are records accessed?

• In any order

• Based on a key field

• In the order they are stored

• Using a hash function

What is the primary difference between symmetric and asymmetric key cryptography?

• Symmetric uses two keys, asymmetric uses one

• Symmetric uses one key, asymmetric uses two

• Symmetric is slower than asymmetric

• Symmetric is more secure than asymmetric

What is the role of a public key in encryption?

• To decrypt messages

• To encrypt messages

• To store messages

• To verify messages

What is plaintext in the context of encryption?

• Encrypted data

• Data that has been compressed

• Unencrypted data

• Data that has been hashed

How does direct file access differ from sequential file access?

• Direct access is slower

• Direct access requires reading all previous records

• Direct access allows records to be read in any order

• Direct access is only used for encrypted files

What is ciphertext?

• Data that has been encrypted

• Data that has been compressed

• Data that has been decrypted

• Data that has been hashed

Which method of file organization allows for records to be accessed based on a key field?

• Serial

• Sequential

• Random

• Direct
