Parameterized queries are a method of structuring SQL queries in a way that separates the query logic from the data, significantly enhancing security by preventing SQL injection attacks. By using placeholders for data inputs, these queries ensure that user input is treated as data rather than executable code, thus maintaining the integrity of the database operations.

User input refers to the data or commands entered into a system by a user, which the system then processes to produce a desired outcome. It is a critical component in human-computer interaction, enabling users to communicate their intentions and receive feedback from the system.

Executable code refers to a set of instructions in a computer program that can be directly executed by the computer's CPU to perform specific tasks. It is typically generated from source code through a process called compilation or interpretation, transforming human-readable instructions into machine-readable binary code.
