6. Threats that are not truly malicious code - but can have indirect negative effects - such as decreasing performance or using up bandwidth. Grayware includes spyware - adware - spam - and spim.






7. A part of the NTFS file system used to store a transaction-based database - with all file accesses treated as transactions - and if a transaction is not complete - NTFS will roll back to the last successful transaction.






8. A wireless network standard that defines speeds of up to 600 Mbps. It is downward-compatible with 802.11a - 802.11b - and 802.11g.

12. A new level of an operating system with major changes to the core components.






13. A power supply that converts between alternating current and direct current.






14. A mat that provides a path to ground for a static charge and is designed for the desktop or floor of a workspace. One placed on the workbench reduces the risk of electrostatic discharge for components placed on it - while one placed on the floor prov






15. A shared folder on a distribution server containing the source files for a remote installation.

25. An organization that creates specifications for infrared wireless communication.






26. Aka hyper threading.






27. A bundle of patches or updates released periodically by a software publisher.






28. In the laser printing process - this is the step in which the cover on the printer's toner cartridge is opened and the toner particles are attracted to the relatively less negatively charged areas of the drum.






29. A subprotocol of IP that detects and reports problems that can cause errors.






30. In the laser printing process - the stage in which the printer's high-voltage power supply (HVPS) conducts electricity to the primary corona wire so it can pass the voltage on to the printer's electro-photosensitive drum.






31. In telecommunications - a technique that combines multiple messages or signals onto a single transmission channel.






32. An Advanced Options menu choice that simply causes Windows to restart normally (if it can).






33. Aka enhanced capabilities port (ECP) mode.
