Retrieval is a process that involves the ACQUISITION and RECOVERY of data or information. It is a common practice in many fields, such as computer science, engineering, and business. The term 'retrieval' is often used to refer to the process of acquiring data from a source, such as a database or a website. The term 'RECOVERY' is used to refer to the process of restoring data that has been lost or corrupted. Both terms are related to the concept of retrieval, but they have different meanings. ACQUISITION refers to the process of obtaining data from a source, while RECOVERY refers to the process of restoring data that has been lost or corrupted.
