17. One of three competing technologies for rewritable DVDs.






18. 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.






19. 'Permanent storage - as in read-only memory (ROM).'






20. 'The system software that controls the way in which a computer system functions - including the management of hardware - peripherals - and software.'






21. A power-management mode that saves the current state of the current system to the computer's hard drive.

36. Unwanted or junk e-mail






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 small circuit board that holds a series of random access memory (RAM) chips.






39. 'In a wireless network - a device that translates the electronic data that needs to be sent along the network into radio waves and then broadcasts these radio waves to other network nodes.'






40. DVD format in which data can only be read and not written.






41. '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.'
