2.1.7. The Application Layer

The application layer is really just a collection of miscellaneous protocols for common activities such as electronic mail, file transfer, and connecting remote terminals to computers over a network. The best known of these are the X.400 electronic mail protocol and the X.500 directory server. Neither this layer nor the two layers directly under it will be of interest to us in this book.
