Hardware: This heading tells you volumes about your hard drives as well as specifics concerning your optical drives; modem; AirPort and Bluetooth hardware; graphics hardware; AC power settings; and any FireWire, eSATA, and USB devices connected to your system. This figure shows the information from a USB screen, with many of the devices expanded so that you can see them. (The text you see at the bottom half of the window is the detailed information on the item that’s selected.)
Display information about your Mac’s ports and connections.Network: This heading shows a listing of your network configuration, active network connections, and other assorted network paraphernalia. You’ll probably need this screen only when asked by a technical support person for the network protocols that you’re using, but it’s handy nonetheless.

If you’re wondering whether you need to update an application with a patch file(to fix bugs in the software) or update a file from the developer, you can look here to check the current version number for the application. You also get a rather boring list of the extensions(or drivers) used by Mac OS X applications. Logs are usually valuable only to tech support personnel; they document recent lockups, application crashes, and even system crashes.
