2.6. Getting an A+

This chapter takes a look at the major functions of an OS; to be prepared for the exam, you should remember the following:

• The OS is responsible managing the interface between all hardware components that make up your computer.

• General Protection Faults (GPFs) and Stop errors are often a result of applications trying to cross memory boundaries.

• Virtual memory is composed of physical memory or RAM and space on your hard drive, in the form of a paging file.

• NTFS is the most robust and stable of the available file systems but is compatible with the fewest other OSes.

• System and application settings are stored in the Registry or in INI files.

• explorer.exe makes up most graphical navigation of your computer and is represented as both My Computer and the desktop.

• Control Panel applets offer interfaces to many system settings for your computer.

• Remote access to computers is available through both Remote Desktop Connections and Remote Assistance, both of which rely on Remote Desktop Protocol (RDP).
