What are advantages of dividing network transmission into layers?
Network communication components are standardised which helps to ensure that different types of hardware and software are able to communicate.
Through separating the overall network communication processes it makes troubleshooting easier should an error occur.
To ensure that if changes are made in one layer they do not affect any other layers
Through dividing overall network communication into smaller, individual components it makes the software development process more straightforward.
Its easier
The purpose of the Application layer is
Prepares or presents the data (email, file, message) for /from transmission - including applying encryption/decryption
Ensures reliable transmission of data across the network.
Ensures the data is correctly routed through the network
Responsible for encoding the data to be transmitted on the actual cabled or wireless channel.
In packet switching each packet will follow the same route
True
False
