1. A device that uses some unique characteristic of human biology to identify authorized users.






2. '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.'






3. 'An alternative to more traditional mapping software programs; easily accessible with any Internet connection and updated more frequently than offline services. Examples include MapQuest - Yahoo! Maps - Google Maps - and Google Earth.'






4. A server used to fulfill one specific function (such as handling e-mail).






5. 'Programs such as Microsoft Outlook or Lotus Organizer that strive to replace the various management tools found on a traditional desk such as a calendar - address book - notepad - and to-do lists.'






6. The memory that the computer's operating system uses.






7. A hard drive that is installed inside the system unit.






8. The most popular transmission media option for Ethernet networks. UTP cable is composed of four pairs of wires that are twisted around each other to reduce electrical interference.






9. 'A type of network design in which users are not responsible for creating their own data backups or providing security for their computers; instead - those tasks are handled by a centralized server - software - and a system administrator.'






10. Any copyrighted software that can be used for free.






11. 'The top level of the filing structure in a computer system. In Windows computers - the root directory of the hard drive is represented as C:.'






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






13. 'Programs that include image - video - and audio editing software - animation software - and other specialty software required to produce computer games - animations - and movies.'






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






15. The set of computer programs or instructions that tells the computer what to do and enables it to perform different tasks.






16. The actual speed of data transfer that is achieved. It is usually less than the data transfer rate and is measured in megabits per second (Mbps).






17. A digit that corresponds to the on and off states of a computer's switches. A bit contains a value of either 0 or 1.






18. An expansion card that enables a computer to produce sounds that are omnidirectional or three dimensional.






19. 'Temporary storage - such as in random access memory (RAM). When the power is off - the data in volatile storage is cleared out.'






20. A temporary storage area on the hard drive where the operating system 'swaps out' or moves the data or instructions from random access memory (RAM) that have not recently been used. This process takes place when more RAM space is needed.






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






22. 'The computer's temporary storage space or short-term memory. It is located in a set of chips on the system unit's motherboard - and its capacity is measured in megabytes or gigabytes.'






23. 'A specialized logic chip that is dedicated to quickly displaying and calculating visual data such as shadows - textures - and luminosity.'






24. '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.'






25. A measure of the greatest amount of light showing when a monitor is displaying pure white; measured as candelas per square meter (cd/m^2) or nits.






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






27. The metal or plastic case that holds all the physical parts of the computer together - including the computer's processor (its brains) - its memory - and the many circuit boards that help the computer function.






28. 'The time it takes for the hard drive's read/write heads to move over the surface of the disk - between tracks - to the correct track.'






29. A signal that tells the operating system that it is in need of immediate attention.






30. A heavily secured server located on a special perimeter network between a company's secure internal network and its firewall.






31. A type of network in which users are responsible for creating their own data backups and for providing security for their computers.






32. A cable that transmits data at close to the speed of light along glass or plastic fibers.






33. 'A physical address - similar to a serial number on an appliance - that is assigned to each network adapter; it is made up of six 2-digit characters such as 01:40:87:44:79:A5.'






34. A UTP cable type that provides more than 1 GB of throughput.






35. A cable that transmits data at close to the speed of light along glass or plastic fibers.






36. The computer's temporary storage space or short-term memory. It is located in a set of chips on the system's motherboard - and its capacity is measured in megabytes or gigabytes.






37. System software that controls hardware devices.






38. A collection of software programs that have been bundled together as a package.






39. A unit of computer storage equal to approximately one thousand bytes.






40. The part of the system unit of a computer that is responsible for data processing ( the 'brains' of the computer); it is the largest and most important chip in the computer. The CPU controls all the functionsperformed by the computer's other componen






41. An active topology (meaning that data is retransmitted) in which the nodes connect to a central communications device called a switch. The switch receives a signal from the sending node and retransmits it to the node that should receive it.






42. 'A process that involves examining incoming data packets to ensure they originated from - or are authorized by - valid users on the internal network.'






43. The process of installing only those features of a software program that a user wants on the hard drive.






44. 'A prediction - named after Gordon Moore - the cofounder of Intel; states that the number of transistors on a CPU chip will double every two years.'
