  10. 10. Working with Storage Media   Early personal computers used floppy disks to store data and programs.   You had to format floppy disks before you could use them.   Now most storage media is preformatted and ready to use.   If you ever need to format a floppy disk, it is a simple process using My Computer.10 Computer Literacy BASICS
  11. 11. Formatting a Disk   Formatting is the process of preparing a disk to hold data.   Formatting organizes a disk into tracks and sectors. –  A track is a narrow band that forms a circle on the surface of the disk. –  A sector is a pie-shaped area that can hold 512 bytes of data.11 Computer Literacy BASICS
  12. 12. Formatting a Disk (cont.)   When you format a disk, any data previously stored on the disk is destroyed.   Each track on a disk is numbered and labeled in the formatting process.   The file allocation table (FAT) on the disk logs the information about each track.12 Computer Literacy BASICS
  13. 13. Opening a Window   You open a window by double-clicking an icon.   This will execute a command and open a window on the desktop.   For example, to open the Recycle Bin, find the icon on the desktop and double-click it.13 Computer Literacy BASICS

  20. 20. Working with Files and Folders   When you use a computer, files begin to accumulate quickly.   You can create folders to hold files of the same type, files for the same project, or files that are somehow related.   Computer folders are similar to manila folders in a filing cabinet. They hold infor- mation about some particular subject.20 Computer Literacy BASICS
  21. 21. Working with Files and Folders (cont.)   You can create folders inside of other folders, called subfolders, to further refine the type of information they contain.   You can move or copy files from one folder or disk to another, but you cannot have more than one file with the same name in a folder.21 Computer Literacy BASICS
  22. 22. Moving a File   Files can be moved from one folder to another by using the Cut and Paste commands.   You can also click and drag a file from one location to another.   Moving a file removes the file from the original folder.22 Computer Literacy BASICS
  23. 23. Copying a File   Files can be copied from one folder to another to create an exact duplicate of the original file in another location.   Use the Copy and Paste commands to make a copy of a file in a new location.   You can right-click on a filename to open a shortcut menu that lists the Copy and Paste options.23 Computer Literacy BASICS
  24. 24. Deleting a File   Files that are no longer needed can be deleted by selecting the file and clicking the Delete option from the File menu.   Or right-click the filename and select Delete from the shortcut menu.   When you delete a file, it is sent to the Recycle Bin. You can recover a file from the Recycle Bin if you have not emptied the bin.24 Computer Literacy BASICS
  25. 25. Selecting Files   To select a group of adjacent files, click the first file to select it. Then hold down the Shift key and select the last file in the list.   To select a group of nonadjacent files, select the first file, hold down the Control key, and click the remaining filenames you want to select. All the selected files will be highlighted.25 Computer Literacy BASICS
