1 Computer Maintenance 2016 Fall Final Review True/False Indicate whether the statement is true or false. 1. A motherboard can have more than one bus, each using a different protocol, speed, data path size, and so on. 2. Some very basic instructions are stored on the motherboard just enough to start the computer, use some simple hardware devices such as a monitor and keyboard, and search for an operating system stored on a storage device such as a hard drive or CD. 3. The electrical requirements for motherboards change over time as new technologies make additional demands for power. 4. The easiest way to fix a power supply you suspect is faulty is to replace it. 5. Most cases have one or more positions on the case to hold a case fan to help draw air out of the case. 6. An overheated system can cause intermittent problems or cause the system to reboot or refuse to boot. 7. Excessive heat can damage the CPU and the motherboard. 8. A hard disk drive (HDD), most often called a hard drive, comes in two sizes for personal computers: the 1.8" size is used for laptop computers and the 2.5" size is used for desktops. 9. Almost all hard drives sold today for desktop computers are magnetic hard drives. Multiple Choice Identify the choice that best completes the statement or answers the question. 10. In the world of computers, the term refers to the computer s physical components, such as the monitor, keyboard, motherboard, and hard drive. 11. The term refers to the set of instructions that directs the hardware to accomplish a task. 12. To perform a computing task, software uses hardware for four basic functions:. 13. A 1 or 0 in this system is called a. 14. A device that is not installed directly on the motherboard is called a(n) device. 15. The is a group of microchips on the motherboard that control the flow of data and instructions to and from the processor. 16. Primary storage is provided by devices called memory or located on the motherboard and on some adapter cards. 17. Everything in a computer is. 18. A power is a box inside a computer case that supplies power to the motherboard and other installed devices. 19. is running a processor, motherboard, or video card at a higher frequency than the manufacturer recommends and is not considered a best practice.

2 20. The provides backup power in the event that the AC fails completely. 21. A color or stripe down one side of a cable marks this side of the cable as pin Older hard drives use a(n) -conductor IDE ribbon cable. 23. For an older motherboard, instead of screws you ll see that keep the board from resting directly on the bottom of the computer case. 24. A(n) might solve the problem of intermittent errors caused by noise in the power line to the PC. 25. connections inside the computer case can cause a system to appear dead or reboot itself. 26. A is the most complicated component in a computer. 27. The and the chipset determine which processors a board can support. 28. The have a lever that is used to lift the processor up and out of the socket. 29. The fast end of hub in the Intel i800 series chipsets, which contains the graphics and memory controller, connects to the system bus and is called the hub s. 30. The slower end of the hub in the Intel i800 chipsets, called the, contains the I/O controller hub. 31. Throughput is sometimes called. 32. A(n) boot involves turning on the power with the on/off switch. 33. The process of upgrading or refreshing the ROM BIOS chip is called BIOS. 34. Some cases have, also called spacers, which are round plastic or metal pegs that separate the motherboard from the case, so that components on the back of the motherboard do not touch the case. 35. With any installation, remember the importance of using a ground strap (ground bracelet) to ground yourself when working inside a computer case to protect components against. 36. Processor core frequency is measured in. 37. Installing more than one processor on a motherboard creates a. 38. The cooler sits on top of the processor and consists of a fan and a heat, which are fins that draw heat away from the processor. 39. If a power-on password has been forgotten, you can use the BIOS to reset the password.

3 40. The CMOS battery failure can be reported by startup BIOS during the. 41. Processors can sense their operating temperatures and report that information to. 42. Intel and AMD both recommend a air guide as part of the case design. 43. memory temporarily holds data and instructions as the CPU processes them. 44. Laptops use a smaller version of a DIMM called a(n). 45. A(n) gets its name because it has independent pins on opposite sides of the module. 46. If the number of bits is not an odd number for odd parity or an even number for even parity, a error occurs. 47. To upgrade memory means to add more to a computer. 48. Higher-quality memory modules have installed to reduce heat and help the module last longer. 49. For modules, small clips latch into place on each side of the slot to hold the module in the slot. 50. When installing the RIMM, on the edge of the RIMM module will help you orient it correctly in the socket. 51. A drive has one, two, or more platters, or disks, that stack together and spin in unison inside a sealed metal housing that contains firmware to control reading and writing data to the drive and to communicate with the motherboard. 52. The top and bottom of each disk of a magnetic hard drive have a(n) that moves across the disk surface as all the disks rotate on a spindle. 53. Each side, or surface, of one hard drive platter is called a. 54. The total number of on the drive determines the drive capacity. 55. During the formatting process, you specify the size of the partition and what file system it will use. 56. is a system BIOS feature that monitors hard drive performance, disk spin up time, temperature, distance between the head and the disk, and other mechanical activities of the drive in order to predict when the drive is likely to fail.

4 57. The -conductor IDE cable has half the number of pins as it has wires. 58. A technology that configures two or more hard drives to work together as an array of drives is called. 59. A drive is a duplication of everything written to a hard drive. 60. When using an 80-conductor cable-select cable, the drive nearest the motherboard is the.
