In terms of the OSI model, explain why a user who knows nothing about all the parts of a network is still able to use a network. Give at least one example of how such a user may use a network.
What will be an ideal response?
A user does not need to know anything about a network to use it. All the user needs to know is how to use an application that ties into software at the top of the OSI layers—the Application layer (Layer 7). For instance, a user only needs to know how to use a Web browser such as Internet Explorer or Mozilla Firefox in order to browse and view Web pages. Similarly, a user can use a program such as Microsoft Outlook to send and retrieve e-mail messages.
