1. A device such as a monitor - printer - or keyboard that connects to the system unit through ports.






2. A concentric circle that serves as a storage area on a hard drive platter.






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






4. 'Software that handles requests for information - Internet access - and the use of peripherals for the rest of the network nodes.'






5. Portable - nonvolatile memory.






6. A block of code in the operating system that software applications need to interact with.






7. The percentage of time a central processing unit (CPU) is working.






8. 'A device connected to a network such as a computer - a peripheral (such as a printer) - or a communications device (such as a modem).'






9. A network located in a home that is used to connect all of its digital devices.






10. A single software program that incorporates the most commonly used tools of many productivity software programs.
