An OID (Object Identifier) is a unique identifier in a hierarchical tree structure that represents a specific object or concept in a certain standard or organization. OIDs are typically used in networking, telecommunications, and other information technology systems to provide a standardized way of identifying and referencing different types of objects, such as devices, protocols, services, or applications. OIDs are defined by standard organizations, such as ISO (International Organization for Standardization) and ITU (International Telecommunication Union), and are commonly used in SNMP (Simple Network Management Protocol) to identify and manage network devices.
