2. 'A hierarchical structure that include files - folders - and drives used to create a more organized and efficient computer.'






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






4. The set of techniques used in processing and retrieving information.






5. Acts as a go-between for computers on the internal network and the external network (the Internet).






6. Programs you can use to design interactive Web pages without knowing any HyperText Markup Language (HTML) code.






7. 'The steady and constant pace at which a computer goes through machine cycles - measured in hertz (Hz).'






8. 'The technology that enables the operating system - once it is booted up - to recognize automatically any new peripherals and configure them to work with the system.'






9. The process of installing all the files and programs from the distribution CD to the computer's hard drive.






10. 'A device on a network such as a router - hub - and switch that moves data signals around the network.'






11. 'Someone who has training in computer and peripheral maintenance and repair - network design - and the installation of network software; installs new equipment - configures computers for users - repairs equipment - and assigns network access to users






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






13. An application program such as Microsoft Excel or Lotus 1-2-3 that enables a user to do calculations and numerical analyses easily.






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

20. 'The essential component of the operating system that is responsible for managing the processor and all other components of the computer system. Because it stays in random access memory (RAM) the entire time the computer is powered on - the kernel is






21. 'A group of two or more computers (or nodes) that are configured to share information and resources such as printers - files - and databases.'






22. 'Small blocks of memory - located directly on and next to the central processing unit (CPU) chip - that act as holding places for recently or frequently used instructions or data that the CPU accesses the most. When these instructions or data are sto






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






24. An operating system (OS) that enables more than one user to access the computer system at one time by efficiently juggling all the requests from multiple users.






25. A network configuration in which the computers and peripherals are laid out in a configuration resembling a circle. Data flows around the circle from device to device in one direction only.






26. 'Software - often used for training purposes - which allows the user to experience or control an event as if it is reality.'






27. A drive that plugs into a universal serial bus(USB) port on a computer and stores data digitally. Also called USB drive - jump drive - or thumb drive.






28. 'A wireless standard established in 1997 by the Institute of Electrical and Electronics Engineers; also known as WiFi (short for Wireless Fidelity) - it enables wireless network devices to work seamlessly with other networks and devices.'






29. A computer that provides resources to other computers on a network.






30. Portable - nonvolatile memory.






31. A portion of the hard drive containing all the different configurations (settings) used by the Windows operating system (OS) as well as by other applications.
