2. A type of network in which users are responsible for creating their own data backups and for providing security for their computers.






3. A temporary storage area on the hard drive where the operating system 'swaps out' or moves the data or instructions from random access memory (RAM) that have not recently been used. This process takes place when more RAM space is needed.






4. A power supply regulates the wall voltage to the voltages required by computer chips; it is housed inside the system unit.






5. A measure of the greatest amount of light showing when a monitor is displaying pure white; measured as candelas per square meter (cd/m^2) or nits.






6. Software that facilitates the communication between a device and the operating system.






7. How a user sets up his or her computer and other equipment to minimize risk of injury or discomfort.






8. A device (such as a printer or external hard drive) that can be attached directly to a network instead of needing to attach to a computer on the network.






9. 'The backslash mark () used by Microsoft Windows and DOS in file names. Mac files use a colon (:) - and UNIX and Linux use the forward slash (/) as the path separator.'
