Which model allows control to be passed sequentially from one layer to the next during data transmission?

The OSI 7 Layer Model allows for control to be passed sequentially from one layer to the next during data transmission. This model consists of seven distinct layers, each of which has specific responsibilities in the process of communication between systems. As data is transmitted, it progresses through each layer in a specific order: from the application layer down to the physical layer on the sending side, and then back up from the physical layer to the application layer on the receiving side.

The sequential passing of control is a key feature of the OSI model. Each layer can only interact directly with the adjacent layers—its immediate upper and lower layers—allowing for modularity and encapsulation of functions. For instance, the presentation layer is responsible for translating data formats and encryption, while the transport layer manages end-to-end communication and error recovery. This design facilitates a clearer understanding of networking processes and promotes inter-layer cooperation while maintaining layer independence.

In contrast, the TCP Model and Internet Model have their own structures which may not emphasize a strict sequential control mechanism in the same way, and the Hybrid Model combines aspects of the OSI and TCP models but does not adhere to the specifically defined seven-layer structure that includes sequential passing of control between layers.
