| Client and server applicationsThere are two stakeholders of the secure communication process:
 
Client application, or client, is an application that tries to establish connection.
Server application, or server, is an application to which the client tries to connect.
 For example, if Acronis Backup & Recovery 10 Management Console is connecting to Acronis Backup & Recovery 10 Agent on a remote machine, the former is the client and the latter is the server.
 An Acronis component can act as a client application, a server application, or both, as shown in the following table.
