12. The style of partition on a basic disk - which includes primary and extended.






13. A square snap coupling for fiber-optic cable - about 2.5 mm wide - used for cable-to-cable connections or to connect cables to network devices. It latches with a push-pull action similar to audio and video jacks.






14. A scaled-down laptop in the ultra-portable category - designed for Internet access. Aka also ultra-portable and mini-notebook.

16. Aka Wireless Fidelity.






17. An assigned channel over which a device can send a signal to the processor to get its attention.






18. A circuit on a motherboard through which incoming power passes. Several voltage regulators maintain a steady voltage as demand goes up and down - with one or more voltage regulators for the various voltages required (5 volts - 12 volts - 3.3 volts -






19. In networks - when data can travel in either direction - but only in one direction at a time.






20. A socket for a PGA CPU that has a retention lever as well as contacts to match the number of pins on the CPU. The lever is used to attach the CPU to the socket in a manner that does not require force to insert or to remove the CPU.

32. Another name for a motherboard in a laptop.






33. A component that you can install into a system onsite - such as memory modules - heat sinks - and CMOS batteries.






34. A power supply that detects the incoming voltage and switches to accept either 120 or 240 VAC.






35. Fiber-optic cable in which multiple light waves can pass simultaneously. Usually larger in diameter than single-mode fiber; and each wave uses a certain portion of the fiber cable for transmission.






36. A type of solid-state storage that is commonly used in a variety of devices - such as digital cameras.






37. Aka read-only memory.






38. To renew a product activation - required when the activation program discovers significant changes in a computer or the activated product has been installed on a second computer.
