Final answer:
The processing when editing a file from a file and print server is done on the client computer. The file and print server provides the file access, but the actual editing occurs on the client side.
Step-by-step explanation:
When a client computer accesses a file and print server, opens a file, and edits it, the processing is primarily done on the client computer. The server provides access to the file, but the actual computation, including running of applications and editing, occurs on the client system. Once the file is edited, the changes can be saved back to the server. The keyboard is simply an input device, and while the server software facilitates the sharing of resources, it does not perform the edits directly. Processing over the network relates to data transfer rather than application processing.
