Across 5. Involve comparing one data item with another to determine whether the first item is greater than, equal to, or less than the other item. 8. Usually has a very small capacity. 9. Is a single chip with two or more separate processor cores. 11. An external device that provides connections to peripherals through ports built into the device. 13. Chips must be re-energized constantly or they lose their contents 14. A chip that contains two separate processor cores. 16. Is a method that uses multiple processors simultaneously to excecute a single program or task. 17. Allows the various devices both inside and attached to the system unit to communicate with eachother. 20. Stores data using magnetic charges instead of electrical charges. 24. Writing the result to memory (not to storage medium). 25. A chip with four separate processor cores. 26. by contrast, does not lose its contents when power is removed from the computer. 28. Is the process of carrying out the commands. 29. Is similar to a USB port in that it can connect multiple types of devices that require faster data transmission speeds, such as digital video cameras, digital VCR's color printers, scanners, digital cameras and DVD drives, to a single connector. 31. The processor relies on a small quartz crystal circuit called the ____ 35. Is the process of obtaining a program instruction or data item from memory. 36. Can be a peripheral or a chip, creates sound from digital instructions. 40. Uses a continuous flow of fluid(s), such as water and glycol, in a process that transfers the heated fluid away from the processor to a radiator-type grill, which cools the liquid, and then returns the cooled fluid to the processor. 43. A case that contains electronic components of the computer used to process data. 45. is a device that enables you to join a port and a connector that are both female or both male. 47. Human speech is ____ because it uses continuous (wave form) signals that vary in strength and quality. 48. Is a small piece of semi-conducting material, usually silicon, on which integrated circuits are etched. 50. Interprets and carries out the basic instructions that operate a computer. 51. Also called Main memory, consists of memory chips that can be read from and written to by the processor and other devies. 52. The amount of time it takes the processor to read data, instructions, and information from memory. 53. Chips are faster and more reliable than any variation of DRAM chips. 54. Refers to memory chips storing permanent data and instructions. 55. Is a small ceramic or metal component with fins on its surface that absorbs and disperses heat produced by electrical components such as a processor. 56. Another component of the processor, performs arithmetic, comparison, and other operations. 57. A type of nonvolatile memory that can be erased electronically and rewriten. 58. Is the number of bits the processor can interpret and execute at a given time.

Down 1. Consists of electronnic components that store instructions waiting to be excecuted by the processor, data needed by those instructions, and the results of processing the data (information). 2. Is a cache on the motherboard that is separate from the processor chip. 3. A 16-bit coding scheme that has the capacity of representing more than 65,000 characters and symbols. 4. When 8 bits are grouped together as a unit, they form a ___. Is also the basic storage unit in memory. 6. This role of memory to store both data and programs is knows as the ___ 7. When the computer's power is turned off, ____ loses its contents 8. Is built directly in the processor chip. 10. An external device that attaches to a mobile computer or device, contains a power connection and provides connections to peripherals; it usually also includes slots for memory cards, optical disc drives, and other devices. 12. Some RAM chips, flash memory chips, and other memory chips use ____ technology because it provides high speeds and consumes little power. 15. The point at which a peripheral attaches to or commmunicates with a system unit so that the peripheral can send data to or receive information from the computer. 18. Is an opening inside the system unit in which you can install additional equipment. 19. Refers to the process of translating the instruction into signals the computer can execute. 21. Contains many microscopic pathways capable of carrying electrical current. 22. (short for binary digit) is the smallest unit of data the computer can process 23. Allows you to insert and remove the removeable flash memory and other devices while the computer is running. 27. A socket on the motherboard that can hold an adapter card. 30. Helps speed the processes of the computer because it stores frequently used instructions and data. 32. Sometimes called a system board, is the main circuit board of the system unit. 33. Sometimes caled expansion card, is a circuit board that enhances functions of a component of the system unit and/or provides connections to peripherals. 34. The component of the processor that directs and coordinates most of the operations in the computer. 37. Enhances the sound-generating capabilities of a personal computer by allowing sound to be input through a microphone and output through external speakers or headphones. 38. A processor contains small, high-speed storage locations, called ___ 39. A 0 and1, called bits 41. Allows a programmer to erase the microcode with an electric signal. 42. A device that connects to the system unit and is controlled by the processor in the computer. 44. Can act as an electronic switch that opens or closes the circuit for electrical charges. 46. Also called a graphics card, converts computer output into a video signal that travels through a cable to the monitor, which displays an image on the screen. 47. Is the most widely used coding scheme to represent data. 49. A device that plugs in a USB port on the system unit and contains multiple USB ports in which you plug cables from USB devices.
