The type of validation that executes all inputs to the server is server-side validation. This means that when data is submitted from a client (like a web browser), it is sent to the server where various checks and validations are performed before processing the data further.

Server-side validation is crucial for maintaining data integrity and security, as it allows the server to verify that the input meets specified criteria, is formatted correctly, and adheres to business logic. This type of validation is executed after the client has submitted the data but before it is permanently stored or manipulated. This means that even if the client-side validations are bypassed (for example, through manipulation of the client-side code), the server will still perform its checks, making it a vital component in the overall validation strategy.

Client-side validation occurs in the browser before the data is sent to the server. While it provides a good initial check and can improve user experience by providing immediate feedback, it cannot be relied upon exclusively for security. This is why server-side validation is essential for ensuring that all inputs are correctly validated and helps to prevent malicious activity, such as injection attacks or erroneous data entries.

Therefore, server-side validation is the correct approach for ensuring that all user inputs are validated comprehensively at the server level
