Answer 4

Data validation means the information is checked for accuracy. This can be done in a number of ways, but it usually means that something is checked against a series of rules or against other data.

If you enter a membership number into a website, for example, it could be validated first by checking it is all numeric and has the right number of digits. If it passes that test, it could be validated further by checking it exists in the membership file.

Answer 5

It usually means checking input before committing it to processing. You see it all the time on the Internet after entering information via a form in a web page; after submitting the form the data is checked to ensure it is valid - i.e., it is validated - before it is accepted; if any errors are discovered they are usually reported to the user who can then correct them before resubmission.

Answer 6

If it validates it says 'yes okay' and allows what you are doing.

If it refuses to validate, you are stuck.

Answer 7

To verify that data or an action conforms to a predefined set of rules.
