gives detailed information about the Wolfram System being run.


gives a list of rules with information about the component "comp".


gives the value of property "prop" for component "comp".


  • 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:
