Answer to Question 1

Information is classified into three types, based on how ordered and organized it is.

For example, a credit card company maintains customer records in a structured format with elements such as last name, first name, street address, phone number, and email address.
Information that has no inherent structure or order is called unstructured information. For example, a manila folder in which educational certificates, employment records, bills, warranties, and medical prescriptions are stored.
