  1. pictures on a computer
    graphic images or graphics
  2. two fundamental types of computer graphics
    bitmapped and vector
  3. when you manipulate this type of graphic, you work with a grid of dots, called pixels. it is created from a rows of colored pixels that together form an image. the simplest of these graphics only have two colors, black or white.
    bitmapped
  4. the typical types of bitmap file formats include PNG, JPG, GIF, and BMP
  5. this type of graphic is created by mathematical formulas that define the shapes used in the image. it consists of shapes, curves, lines, and test that together make a picture. they contain instructions about where to place each component.
    vector graphic
  6. typical formats for vector images are WMF, SWF, and SVG
  7. a device that is used to add graphic files to your computer. it converts an existing paper image into an electronic file.
    scanner
  8. another popular method is to use an external or built-in digital camera to take photos and then store the images on your computer. you can also capture images displayed on your computer monitor and save them as graphics.
  9. this tool can be used to capture a window, tile, or any other part of the screen
    snipping tool
  10. a space saving technique. some other compression methods save space without sacrificing image quality, and others are designed to save as much space as possible, even if the image is degraded.
    compression
  11. compresses images without losing quality and allows animation. not suitable for photographs. used for graphics such as logos, line drawings, and icons.
    graphics interchange format. (GIF)
  12. efficiently compresses photographic images. can reduce quality. used for photographs and images with fine detail.
    joint photographic experts group. (JPG or JPEG)
  13. compresses images without losing quality. does not allow transparency. used nonphotographic images designed for the web.
    portable network graphics (PNG)
  14. maintains image quality in print and on screen. some web browsers cannot display these images. used for images used in desktop publishing, faxes, and medical imaging.
    tagged image file format (TIF or TIFF)
  15. simplest way to store a bitmapped graphic. can waste large amounts of storage space. used for basic shapes and images with few colors.
    windows bitmap (BMP)
  16. the undo button can be used on paint's quick access tool bar. you can reverse up to your last three actions on paint.
  17. reducing the width or height of the canvas is one way to crop or remove a row or column of pixels from an edge of a graphic. you can also resize the canvas if you want to make it larger than the image so you can add more graphic elements to the picture.
  18. one way to import pictures to your computer is to connect a device directly to the computer using a cable that plugs into the computer's USB port. another way is to import pictures using a memory card reader, a device that plugs into your computer's USB port.
  19. in both ways of importing a picture to your computer, windows 8 should recognize your camera or card (it recognizes most makes and models of digital cameras and cards), and guide you through the steps of importing pictures.
  20. the most popular way to share photos is to post them on a photo sharing web site or another type of site where you have an account, such as Facebook or Skydrive. the easiest way to share photos with sky drive or email is to use the share charm on the charms bar.

  61. this copies files and folders from a hard disk to a specified location and then automatically compresses them
    backup program
  62. these locations should include all of your documents, pictures, music, videos, compressed folders, and other personal files. file history does not backup files stored in any other locations. for example, file history does not let you back up system files, program files, web email not stored on your hard disk, files in the recycle bin, temporary files, or user profile settings.
  63. the first time file history backs up your files it creates a folder named this in your backup location an then copies all of the files saved in libraries on the desktop and as favorites or contacts, except for those folders you excluded from

    cluster
  78. if a file doesn't fit into one cluster, windows locates the next available cluster and puts more of the files in it. windows attempts to place files in contiguous clusters whenever possible. the file is saved when windows has placed all of the file data into clusters
  79. a disk that contains file whose cluters are not next to each other is said to be this
    fragmented
  80. the more fragmented the disk, the longer windows takes to retrieve the file and the more likely you are to have problems with the file
  81. defragmenting rearranges the clusters on a disk so each files clusters are adjacent to one another. when a disk is in this state, it is said to be optimized. to defragment a disk, you use the optimize drives tool, which rearranges the data on your hard disk and reunites fragmented files so your computer can run more efficiently.

  115. this report includes a number of sections. the first section identifies the computer, the date of the report, and the length of time windows spent collecting the data for the report. the second section, diagnostic reports is especially helpful to system administrators.
    system diagnostics report
  116. USB flash drives eventually wear out after a certain number of uses, so using ReadyBoost can wear out the USB drive, although it generally takes a few years
  117. the first step to troubleshooting. describe the trouble that you observe. be as specific as possible.
    define the problem
  118. the microsoft community is a web site that provides support information for microsoft product users. it is a valuable resource when you are troubleshooting computer problems. it can sometimes be difficult to pinpoint the answer to your question. you can search the microsoft community for answers by entering one or more keywords. the web page will display the answer or support articles associated with those keywords
  119. besides using a troubleshooter to detect and repair problems for you, you can also use the devices and printers window to troubleshoot some typical printing errors, such as problems with print quality
