0:04 Select a supported PC and open Desktop from the topology toolbar.

0:16 Open an app with its icon, then use the taskbar to switch between open apps.

0:28 File Manager browses the simulated device’s files and directories.

0:36 Use the breadcrumb to move back through directories; File Manager is read-only.

0:50 The Desktop Terminal runs commands on this same simulated device.

0:59 Create a small file in Terminal and read its contents back.

1:11 Reopen File Manager to see the file created in Terminal.

1:23 Text Editor is a temporary scratchpad, separate from the device filesystem.

1:35 Closing Text Editor discards its text, so do not use it to save device files.

1:49 Network Settings shows the selected interface’s current IPv4 address and routes.

2:05 Apply a deliberate address change, then check the actual result in Terminal.

2:21 Restore the original address before continuing with this prepared lab.

2:34 Use Web Browser to open a reachable web service inside the simulated lab.

2:50 If that service is stopped, the page is unavailable; restore the service before trying again.

3:07 This browser is for supported lab pages and requests, not general internet browsing.

3:20 System Monitor reports CPU and memory as unavailable rather than measured values.

3:38 Calculator provides basic arithmetic within the Desktop.

3:56 Close and reopen Desktop to start fresh app windows while keeping device state.

4:10 Desktop availability depends on the device; an ordinary router does not provide this PC interface.

4:27 Finish with the lab’s address and web service restored, and close any apps you no longer need.
