- 2. how many layers are there in the Upper Layers?
- 4. how many layers are there in the Lower Layers?
- 8. Layer, is the user interface that internet users interact with to send or receive data through email, online games, peer to peer file transfer, and other applications.
- 9. Layer, establishes a “mechanism for opening, closing and managing a session between end-user application processes and responses”.
- 10. Layer, to enable different networks to be interconnected. It does this by forwarding packets to network routers, which rely on algorithms to determine the best paths for the data to travel.
Down
- 1. Layer, consists of the physical components in a Local Area Network (LAN) such as networking hardware and Ethernet cables.
- 3. Link Layer, ensures that a transmission occurs without any errors.
- 5. Systems Interconnection Model, is a conceptual model that characterises and standardizes the communication functions of a telecommunication or computing system without regard to its underlying internal structure and technology.
- 6. Layer, provides transparent transfer of data between end users, providing reliable data transfer services to the upper layers.
- 7. Layer, translates the commands received from the application layer into universal, well-known networking formats.
