1. A port that uses a traditional telephone signal to connect a computer to the internet.






2. A system of networking connections in which all devices are connected to a central cable called the bus (or backbone).






3. 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.






4. The access method that ring networks use to avoid data collisions.






5. 'Software that handles requests for information - Internet access - and the use of peripherals for the rest of the network nodes.'






6. A measure of the difference in light intensity between the brightest white and the darkest black colors that a monitor can produce. If the contrast ratio is too low - colors tend to fade when the brightness is adjusted to a high or low setting.






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






8. A device that holds all permanently stored programs and data; can be located inside the system unit or attached to the system unit via a USB port.






9. A specially designed computer chip that resides inside another device - such as a car. These self-contained computer devices have their own programming and typically neither recieve input from users nor interact with other systems.






10. A compact audio-video interface standard that carries both high-definition video and uncompressed digital audio.






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

13. Portable - nonvolatile memory.






14. One of three competing technologies for rewritable DVDs.

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






22. '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.'






23. A port that is slightly larger than a standard phone jack and transfers data at speeds of up to 10 -000Mbps; used to connect a computer to a DSL or cable modem or a network.






24. Software that enables users to 'test' the software by running it for a limited time free of charge.

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






36. 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.






37. 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.






38. 'A collection of related pieces of information stored together for easy reference; in database terminology - a file or table is a group of related records.'






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






40. A device that sends processed data and information out of a computer in the form of text - pictures (graphics) - sounds (audio) - or video.






41. The most commonly used wired Ethernet standard deployed in devices designed for home networks which provides bandwidth of up to 1 Gbps.






42. The process of connecting to a wireless network without the permission of the owner of the network.






43. '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.'
