1. A software program or hardware device designed to prevent unauthorized access to computers or networks.






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






3. A large printer that uses a computer-controlled pen to produce oversize pictures that require precise continuous lines to be drawn - such as maps and architectural plans.






4. The technology used in flat-panel computer monitors.






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






6. The ability of an operating system to perform more than one process at a time.






7. A network device that is used to send data between two different local area networks (LANs) or two segments of the same LAN.






8. The maximum speed at which data can be transmitted between two nodes on a network; usually measured in megabits per second (Mbps). See also data transfer rate.






9. When data merely travels the entire length of the communications medium and is received by all network devices.






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






11. An expansion card that attaches to the motherboard inside the system unit and that enables the computer to produce sounds by providing a connection for the speakers and microphone.






12. A nonimpact printer that sprays tiny drops of ink onto a paper.






13. 'The process of looking at a computer's subsystems - what they do - and how they perform to determine whether the computer system has the right hardware components to do what the user ultimately wants it to do.'






14. 'A program with a specific purpose that must guarantee certain response times for particular computing tasks - or else the machine's application is useless. Real-time operating systems are found in many types of robotic equipment.'






15. A circuit board with specific functions that augment the computer's basic functions and provide connections to other devices; examples include sound card and video card.






16. 'A mini-application that runs on the desktop - offering easy access to a frequently used tool such as weather or a calendar item.'






17. 'The backslash mark () used by Microsoft Windows and DOS in file names. Mac files use a colon (:) - and UNIX and Linux use the forward slash (/) as the path separator.'






18. Software that provides street maps and written directions to locations.






19. 'The process of identifying a computer user - based on a login or username and password. The computer system determines whether the computer user is authorized and what level of access is to be granted on the network.'






20. 'A method of optical storage for digital data - developed for storing high-definition media. It has the largest storage capacity of all optical storage options.'






21. 'An operating system originally conceived in 1969 by Ken Thompson and Dennis Ritchie of AT&T's Bell Labs. In 1974 - the UNIX code was rewritten in the standard programming language C. Today there are various commercial versions of UNIX.'






22. An expansion card that provides the computer with a connection to the internet via conventional phone lines.






23. 'A device that reads information from a magnetic strip on the back of a credit card-like access card (such as a student ID card); card readers are easily programmed by adding authorized ID card numbers - Social Security numbers - and so on.'






24. A small camera that sits on top of a computer monitor (connected to the computer by a cable) or is built into a notebook computer and is usually used to transfer live video.






25. Custom software application that is owned and controlled by the company that created it.

27. A specialized computing device designed to store and manage network data.






28. The ability to easily add more users to a network without affecting the performance of the other network nodes (computers or peripherals).






29. BD-ROM is defined as BluRay Disc Read Only Memory. BD-ROM is an optical disc storage media format for high-definition video and data storage.






30. A network used to connect wireless devices (such as Bluetooth-enabled devices) in close proximity to each other.






31. A device that amplifies your wireless signal to get it out to parts of your home that are experiencing poor connectivity.






32. A method of optical storage for digital data that has greater storage capacity than compact discs.






33. An index of all sector numbers that the hard drive stores in a table to keep track of which sectors hold which files.






34. The process by which great amounts of data are analyzed and investigates to spot significant patterns or trends within the data that would otherwise not be obvious.






35. 'A network topology in which each node on the network is responsible for retransmitting the token - or the data - to other nodes.'






36. 'A thin - round - metallic storage plate stacked onto the hard drive spindle.'






37. A program that helps coordinate all print jobs being sent to the printer at the same time.






38. Anyone who unlawfully breaks into a computer system (whether an individual computer or a network).






39. A program that takes out redundancies in a file to reduce the file size.
