Define the tasks for which SNS is used
SNA can be used for the following types of tasks:
- Terminal access to mainframe and midrange computer applications.
- File transfer of data among computer systems.
- Printing of mainframe and midrange data on SNA printers.
- Program-to-program communications that permit applications to exchange data over the network.
SNA can be executed in a networking infrastructure that uses either a hierarchical or peer-to-peer model.
