Details
- When run in a notebook interface, the output of SystemInformation [] displays in graphical form.
- SystemInformation [All ] always gives a list of rules.
- Typical possible components to specify include:
-
"Kernel" Wolfram Language kernel used for evaluation"FrontEnd" Wolfram System front end used for display"Links" external links"Devices" devices, drivers, etc."Network" network connectivity"Machine" available memory, memory in use, page size, etc.
- SystemInformation ["comp","Properties"] gives a list of names of properties for component "comp".
- SystemInformation ["Components"] gives a list of names of components.
- SystemInformation ["Small"] gives an abbreviated list of useful properties.
- SystemInformation gives information on the kernel in which it is evaluated, and the front end in which it is displayed.
- SystemInformation ["comp",…] returns Missing ["NotActive"] if the specified component is not active in your current system.

Possible Issues (1)
Screen area measurements in points, not pixels:
To compute pixel measurements, query the dimension in points and the resolution in pixels per inch:
Scale the points values by the resolution/72 to determine the corresponding pixel values:
