1. A small segment of data that is bundled for sending over transmission media. Each packet contains the address of the computer or peripheral device to which it is being sent.






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






3. 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.






4. Measured in degrees - this tells how far you can move to the side of (or above or below) the monitor before the image quality degrades to unacceptable levels.






5. One of the fastest ports available - moving data at 800Mbps.






6. When the operating system processes the task assigned a higher priority before processing a task that has been assigned a lower priority.






7. 'A single-user - single-task operating system created by Microsoft. MS-DOS was the first widely installed operating system in personal computers.'






8. 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.






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






10. 'A device that enables the computer (or peripheral) to communicate with the network using a common data communication language - or protocol.'






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. The language computers use to process data into information - consisting of only the values 0 and 1.






13. A single copper wire surrounded by layers of plastic insulation and sheathing; used mainly in cable television and cable Internet service.






14. 'A section of a hard drive platter - wedge-shaped from the center of the platter to the edge.'






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






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






17. An application that is still under development.






18. 'The process that occurs after the read/write head of the hard drive locates the correct track - and then waits for the correct sector to spin to the read/write head.'






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






20. '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.'






21. An expansion card that is installed inside a system unit to translate binary data ( the 1s and the 0s the computer uses) into the images viewed on the monitor.






22. 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






23. A device similar to a switch in an Ethernet network. It takes the place of a wireless network adapter and helps relay data between network nodes.






24. '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.'






25. 'The set of programs on a computer that helps a user carry out tasks such as word processing - sending e-mail - balancing a budget - creating presentations - editing photos - taking an online course - and playing games.'






26. A Windows utility that removes unnecessary files from the hard drive.






27. The design of a computer network; includes both physical and logical design.






28. A common output device that displays text - graphics - and video as soft copies (copies that can be seen only on screen).






29. Programs for creating or editing two-dimensional line-based drawings.






30. 'A network - consisting of client and server computers - in which the clients make requests of the server and the server returns the response.'






31. An agreement between the user and the software developer that must be accepted before installing the software on a computer.






32. 'Programs for managing finances - such as Intuit's Quicken and Microsoft Money - which include electronic checkbook registers and automatic bill payment tools.'

36. A fast transfer port.






37. '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.'






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






39. 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.






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






41. The science of using nanostructures to build devices on an extremely small scale.






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






43. A topology comprised of several topologies and combined into one network.






44. 'A device designed to store media - share media across the network - and back up files on computers connected to a home network.'






45. Software that facilitates the communication between a device and the operating system.






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