1. A technology developed in the 1980s for storing data. Variations of this format are in use today.






2. The original digital discs created in 1995 for storing video.






3. Aka direct current.






4. In reference to IDE PATA drives - the master drive on the first channel.






5. The use of two or more video adapters (hence the term "GPU") to drive a single display for the purpose of increasing performance.






6. A single-pin RCA phone jack for transferring digital audio from CD and DVD players to amplifiers and speakers.






7. An installation of Windows that is not automated - where the user is required to pay attention throughout the entire process to provide information and to respond to messages. Also called a manual installation.






8. A memory module (stick) that installs into matching DIMM sockets found on many motherboards. The word "dual" refers to the separate pins or connections on both sides of the module and socket.






9. A double-sided - single-layer digital versatile disc (DVD) that stores 9.4 GB of data - or over four hours of video.






10. A virtual communication circuit that is created and remains available between two endpoints - which are normally some form of data terminal equipment (DTE). Telecommunications companies provide PVC service to companies requiring a dedicated circuit b






11. A multi-GPU solution developed by NVIDIA.






12. A portion of system memory used by a video adapter built into a motherboard.






13. Aka Internet service provider.






14. Aka Advanced Technology Attachment.






15. The practice of forcing a CPU or other computer component to run at a higher clock rate than the manufacturer intended.






16. A DVD of any type that can store data on both sides of the disc.






17. A measurement of the volume of electrons - also called current. It is calculated with the formula amps = watts / volts.






18. The sudden and uncontrolled movement of electricity from an object with a greater charge to one with a lesser charge. Also called static electricity.






19. The location where a cable attaches to a computer. Alternatively - a connector on a motherboard for memory - CPUs - power - or other circuitry.






20. A 20- or 24- pin connector that supplies power from a PC's power supply to the motherboard.






21. A technology that makes 802.11n speeds possible - using multiple antennas to send and receive digital data in simultaneous radio streams that increases performance.






22. In a CPU - the speed at which it can potentially execute instructions - measured in millions of cycles per second






23. Any writable mass storage device - removable or fixed in place.






24. A special modifier key on a laptop keyboard that when pressed together with certain alphanumeric keys - changes the output of the pressed key. It is often called the function key.






25. Cable that consists of pairs of wires twisted around each other. The twists help to boost each wire's signals and make them less susceptible to electromagnetic interference (EMI).






26. A drive that is mapped to an empty folder on an NTFS volume and is assigned a drive path rather than drive letters.






27. 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.






28. A portable computer small enough to fit in your hand - also referred to as a "palmtop" computer. Because it is so small - a PDA does not have the functionality of a laptop or desktop computer. In other words - a typical PDA allows you to perform only






29. A subprotocol of IP that detects and reports problems that can cause errors.






30. Aka Compact Disc-Read-Only Memory.






31. Describes the VGA mode color setting that - although it can produce around 16 million different colors - can only display up to 256 different colors at a time.






32. A type of motherboard and its variants most commonly used in recent PC systems.






33. A virtual tunnel created between two endpoints over an untrusted network. The tunnel is created by encapsulating the packets within special packets for the tunnel. Other security methods are also usually applied to a VPN - such as encrypting the data






34. A pixel that is permanently turned on - causing the pixel to show constantly as red - green - or blue. Also called a stuck pixel.






35. Data communications over the cellular telecommunications networks.






36. In a laptop - a compartment that holds a single media device that is switchable with another.






37. Digital versatile disc (DVD) discs that can be written to - but data cannot be overwritten. This standard is newer than DVD-R. This term also refers to the drives that can write to these discs.






38. A chip that works with a serial port - converting outgoing data from parallel to serial and incoming data from serial to parallel.






39. An underlying protocol that supports Microsoft Remote Desktop.






40. The former name of the Parallel AT Attachment (PATA) interface standard.






41. A computer's temporary working space - usually in DRAM chips.






42. The appropriate responses that you make during a conversation.






43. The type of battery used in the first portable PCs - which was heavy and inefficient.






44. In networking - this is a set of rules for using network hardware and software. In most discussions about networks - this term is assigned to certain network software components.






45. Aka virtual circuit.






46. Software installed on a computer without permission that collects information about a user in order to display targeted advertisements - in the form of either inline banners or pop-ups. Inline banners are advertisements that run within the context of






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






48. Aka World Wide Web.






49. A password that meets certain criteria in order to be difficult to crack. One definition of a strong password is one that contains at least eight characters - includes a combination of letters - numbers - and other symbols ( _ - - - $ - and so on) an
