1.  The measurement in inches from one corner of the screen diagonally across to the opposite corner. Actual size on the monitor.
2.  The number of vertical and horizontal pixels that a device displays on a screen is               . Higher             makes images clearer.
3.                   is a device that not only provides surge protection, but also furnishes your computer with battery backup power during a power outage.
4.  Microprocessor                is a timing device that sets the pace for executing instructions. Speed is specified in megahertz or gigahertz.
5.                  bits are in a byte.
6.  A storage               is the mechanical apparatus that records and retrieves data from a storage medium.
7.  The segment of the data bus to which peripheral devices connect is the                            .
8.                  is a limited version of Windows that allows you to use your mouse, screen, and keyboard, but no other peripheral devices. Diagnostic mode. Hit function          to at the startup menu.
9.                   and                    are usually classified as an output device because it typically shows the results of a processing task.
10.                        stores data by magnetizing microscopic particles on a disk or tape surface. Examples are tape drive or floppy disk.
11.  If a program exceeds its allocated space, its operating system uses an area of the hard disk, called                 , to store parts of programs or data files until they are needed. Really slow.
12.  A CRT's                                 is the speed at which the screen is repainted.
13.  If a read-write head runs into a dust particle or some other contaminant on the disk, it might cause a                           .
14.                    means it requires electrical power to hold data.
15.                        are the lighter, non-pitted surface areas of an optical storage disk.
16.                                    suddenly replaces the usual graphic screen display with an enigmatic error message written in white context against a black background. Indicates operating system has encountered a problem from which it cannot recover, and the computer no longer accepts commands.
17.  A                 produces an image by manipulating light within a layer of liquid crystal cells. Not a high voltage in screen.
18.                     is a type of memory circuitry that hold's the computer's startup routine.             is permanent and non volatile.
19.              is a special high speed memory that allows a microprocessor to access data more rapidly then from memory located elsewhere on the system board. Temporary storage area.
20.  A            can print on both sides of the paper.
21.  Storage            is the disk, tape, CD, DVD, paper, or other substance that contains data.
22.                          is a sudden increase or spike in electrical energy affecting the current that flows to electrical outlets. Can destroy a computer supply.
23.                is a high capacity storage technology with a 25GB capacity per layer.
24.                      designates input,                   and storage equipment that might be added to a computer system to enhance its functionality.         is anything connected to the back of a computer.
25.  In RAM,  microscopic electronic parts called               hold the bits that represent data.
26.                         is a non-volatile chip that requires no power to hold data. Holds computer configuration settings, such as date and time, hard disk capacity, number of floppy disk drives, and RAM capacity. Store its basic hardware.
27.                        are the dark spots on an optical storage disk.
28.                    uses the same sort of glass tube as an old-style television. Has high voltage.
29.                   stores data as microscopic light and dark spots on the disk surface. Examples CD, DVD, and Blu-Ray
