Understanding all the processes and procedures involved in networking management systems is not that easy. There are also a lot of things that should be taken into consideration such as the resources to be used and users that will be responsible in maintaining the whole network. Because of this, the International Organization for Standardization or ISO has devised a network management model to help simplify the different tasks that should be applied to make sure that the network will run as designed. Under the direction of the Open Systems Interconnection or OSI group, the four parts of the OSI/ISO network management model were recognized as follows: (a) Organization; (b) Information; (c) Communication; and (d) Functional.

Organization addresses all the various components of the network management system such as the users, objects, agents and manager. The individual tasks of these resources make up a broader and larger objective, making them interconnected with each other. The relationship between network components is also a part of organization.

Next in line is information. It deals with the processes needed for storage of vital network management information. The management information base or MIB is the bearer of all these valuable information and the syntax and semantics stored in it defines the structure of management information or SMI.

Communication, on the other hand, describes the processes to transfer data between an agent and a manager, along with the different commands and responses transmitted by other users of the system.

Lastly, functional involves all network management applications that are located in the Network Management System or NMS.
