2. Software that runs on the computers in a network and that receives services from servers.






3. A 9-pin D-shell connector.






4. In a CPU - special memory that resides outside the CPU's core and is used to temporarily store instructions and data in order to increase the processing speed. Also called Level 2 (L2) cache and Level 3 (L3) cache - depending on the design of the CPU






5. In a laser printer - a wire that stretches across the printer's drum - not touching it - but positioned very close to the drum's surface so it can pass high voltage to the drum.






6. The moving of data from one storage device to another.






7. A type of switched network used by phone companies.






8. The protocol used to allow client computers to pick up e-mail from mail servers. The current version is POP3.

10. A popular inkjet printer developed by Canon.






11. The wireless nodes (including the WAP) communicating together in infrastructure mode.






12. The memory space - program code - data - and system resources required by a running program.






13. The role of the second EIDE drive on a PATA channel.






14. Aka accelerated graphics port.






15. Aka uniqueness database file.






16. Aka point-to-point protocol.






17. One or more chips designed to work closely with the CPU. Two parts of this chipset are the Northbridge and the Southbridge.






18. A remote KVM switch that captures the keyboard - video - and mouse signals - encodes them into IP packets - and sends them over an IP network.






19. A memory error-checking method in which the parity bit is used to ensure that the total number of 1s in the data stream is odd.






20. The process that authenticates a user and verifies the user account's level of access to a resource.






21. Client software for browsing and accessing the content on the World Wide Web. Examples include Internet Explorer and Firefox.

33. Aka second-level domain.






34. A parallel port mode in which the signals can be transmitted in both directions between the PC and parallel devices connected to the computer.






35. Electrically erasable programmable ROM. A ROM chip that is erasable using an electrical charge.






36. A connector that is slightly larger than an RJ-11 connector and contains eight wires. RJ-45 connectors most commonly attach twisted-pair cables to Ethernet network cards.






37. A CPU power-saving mode that allows a CPU to reduce its speed without losing its place so it does not stop working altogether. SMM also allows the CPU to trigger power saving in other components.






38. A device that takes video output and projects it onto a screen for viewing by a larger audience.






39. Memory chips that use a special Rambus channel that has a data transfer rate of 800 MHz. A double channel width results in a 1.6 GHz data transfer. RDRAM sticks use special RIMM slots.






40. The chunks into which the TCP protocol packages data. In addition to the data - each datagram contains information - stored in a header - which is used by the TCP protocol on the receiving end to reassemble the chunks of data into the original messag






41. Aka virtual file allocation table.






42. A non-routable network protocol suite for use only in small networks.






43. Aka arithmetic logic unit.
