What process involves checking the information entered on a website to ensure its accuracy?

The process that involves checking the information entered on a website to ensure its accuracy is known as validation. Validation is applied to ensure that the data provided by users conforms to specific criteria and formats before it is processed or stored. This typically includes checks for valid data types, ranges, and structural conditions (such as a valid email format or ensuring required fields are completed).

For instance, in a registration form, validation would ensure that the email address includes "@" and a domain, and that the password meets certain complexity requirements. This helps to catch errors early in the data entry process, reducing the likelihood of processing invalid or incomplete data further along.

While verification, authentication, and confirmation are related concepts in data handling, they serve different purposes. Verification generally refers to the process of confirming that information is accurate after it has been collected, such as cross-checking the data against a reliable source. Authentication is about establishing the identity of a user, confirming that they are who they claim to be, often through usernames and passwords or other methods. Confirmation can imply a final check to ensure that the user is satisfied with their input before submission but does not necessarily focus on ensuring data accuracy or validity in the same manner as validation does.
