• Object identifies and deseriptor : unique ID and neve for the object type.

• syntex : used to model the object

• access : implementation requirements

• definition : textual description of the sementies of object type

• The internet object model is a scalor model and is easy to understand. in contrast, the OSI perspective of a managed object is complex and has a different set of characteristics.

• OSI specifications are object oriented and hence a menaged object belongs to an object class

• The attribute of an object defines the external perspective of the object.

• An OSI managed object has following charecterstics

• Object class : managed object

• attributes : attributes visible at its boundary

• operations : operations that can be applied to it

• behaviour : behaviour exhibited by it is response to an operation

• notification : notifications emitted by the object
