The is a that defines the structure and functionality of a network system. It consists of seven layers: the , , , , , , and . Each layer in the OSI model has its own specific functions and s.
At the lowest level, the Physical Layer deals with the actual transmission of bits over physical media such as cables or wireless signals. Each layer in the OSI model relies on the layer below it to carry out its functions effectively, resulting in a highly integrated and .
The importance of protocol within the OSI Network Stack cannot be overstated. By having well-defined protocols for each layer, different manufacturers can develop compatible systems and ensure interoperability. This standardization also enables of network components, giving organizations the to choose products from various vendors without compatibility issues.
Moreover, the layered architecture of the OSI model brings to network systems. If an issue arises in a specific layer, it can be addressed without impacting the functioning of other layers. This modular approach enhances fault tolerance and facilitates troubleshooting.
