1. A file system used by operating systems for organizing - reading - and writing optical discs.






2. Aka Wireless Fidelity.






3. A firewall service that inspects (or filters) each packet that enters or leaves the network - applying a set of security rules defined by a network administrator - and not allowing packets that fail inspection to pass between networks.






4. An area on the top left of the Windows XP Start menu containing shortcuts to Windows Update and programs for browsing the Internet and using e-mail.






5. Aka refresh rate.






6. In reference to the Windows operating systems - one that can utilize more than 4 GB of address space. Depending on the version - 64-bit Windows can address a maximum of from 8 to 192 GB.






7. The disruption of signal transmission caused by the radiation of electrical and magnetic fields. Electric motors are a common source of EMI.






8. One of many low-level instructions built into the control unit of a CPU. Also called a microprogram.






9. The oldest of the Wi-Fi encryption standards. It uses 64- or 128-bit encryption that is easily broken. It does not encrypt the actual data in a packet - and it does not perform user authentication on a packet.






10. Memory chips that provide much slower access than SRAM chips but that can store several megabytes of data on a single chip (or hundreds of megabytes - or even gigabytes - when they are packaged together on a "stick").






11. Aka random access memory.






12. A DVI mode that supports downward compatibility with analog displays.






13. In Windows - an Advanced Options menu choice that starts Windows without several drivers and components and loads only very basic - non-vendor-specific drivers for mouse - video - keyboard - mass storage - and system services. It also displays in low






14. A data encryption technology used for securing data transmitted over the Internet. TLS succeeded SSL.






15. Aka systray.

28. A security feature introduced in Windows Vista to prevent unauthorized changes to Windows.






29. The process of using an oscillating magnetic field to reduce and randomize the magnetic field that builds up on the shadow mask of a CRT monitor.
