Glossary print queue An area in which all print jobs for a specific printer wait to be printed. The print queue holds the jobs so that you can get on with your work in Windows. As the printer becomes available to print a job, the queue sends them along, one by one. print server The server that manages the printing for all users on a network. It receives all requests for print jobs sent by the networked PCs, places the jobs in a queue to wait their turn, and then routes the job to available printers attached to the server. program virus Viruses that attach themselves to executable files and load themselves into memory when you run the file. The file might be an EXE or COM file, but it also might be a SYS, DLL, BIN, or other file on your system. If you double-click an infected EXE file, such as an ani- mation file you receive from a friend, the virus activates and spreads through your computer. proprietary Describes a protocol or communications system that was developed by a com- pany rather than one that follows established standards. protocol Part of software is a language that the computers can use to communicate, called a protocol. Windows contains three such protocols from which you can choose. proxy server These servers control what the user can and cannot access on the Internet. Proxy servers also might reduce user wait times by relieving bandwidth congestion, offer net- work security features, log events, and so on. Some proxy server software is installed on a dedicated computer that acts as a gateway and barrier between the LAN and the Internet. QoS Short for quality of service. QoS is Microsoft’s addition to Windows 2000 and XP, although it is used by other manufacturers, to enable a smoother flow of traffic on the network. An administrator can set higher and lower priorities on a network using the QoS settings. quick logon This type of logon ignores any network drive connections you might have set so that you can get on the network and start working immediately. radio frequency RF A method of wireless networking, radio frequency describes the num- ber of times per second a radio wave vibrates 900 MHz, in this case. Radio signals penetrate light obstacles, such as thin walls. radio frequency shielding Also called RF shielding, this is usually a thin piece of metal placed between a circuit board and other electronic equipment to help prevent interference with the circuit board. RAM random access memory Temporary memory in a computer. The memory stores the data related to a task that the processor is currently dealing with. RAMDAC RAM digital-to-analog converter In a video card, RAMDAC is the electronic com- ponent that changes the digital video signal of the card to a signal the monitor can read. RAM- DAC speed affects the speed of images appearing on the screen. The standard RAMDAC is 135 MHz, although some cards are faster. The faster the RAMDAC, the better. Random Access Memory See RAM. RARP Reverse Address Resolution Protocol One of the TCPIP protocols; it translates physical network addresses into IP addresses. read-only access Sharing option that enables others to open and view folders, or open, view, and copy files; however, read-only access doesn’t enable others to modify a file or delete anything.
