Windows
1a. A Disk Operating System is software that allows the user to communicate with the computer. It automatically loads from the hard disk to the
memory in a process called booting.
1b. GUI is an acronym for graphical user interface. A GUI uses pictoral icons to perform tasks.
1c. Application software is any software that is designed for a specific task (or application.) The interface of many applications are similar.
4a. The Windows 98 desktop is a GUI.
4b. The task bar in Windows 98 displays all of the applications running at that time. Through the task bar, users can rapidly switch between running programs.
4c. Icons represent programs or files.
5. All windows have common characteristics. Each has a title bar (shows the title of a window), a menu bar (shows keywords that can be clicked on to reveal more options), a work area (where the task is performed), and a status bar (shows what is happening). On the top right hand corner of the title bar there are three buttons: a minimize button (used to hide the window from the desktop and leave it running on the task bar), a maximize button (used to make that window fill all of the available screen), and a close button (used to exit and close that window). There are also two scroll bars (one vertical and one horizontal) used for navigating the window and a resize tab used to change the size of the window.
6a. A menu is a cascading list of available commands that appear from a keword on the menu bar.
6b. The Save command could be accessed in two ways without using the mouse. One way is to use its shortcut command which is shown when the menu is open. For saving, Ctrl and S simultaneously will open the save window. Also, using Alt and the underlined letter of the keyword on the menu bar will open that menu which can be navigated through using the arrow keys.
7a. A dialog box supplies the neccesary information used to execute a command properly. It contains options which the user can specify and control.
7b. A default option is one an option that is preselected and will be triggered by the use of the enter button unless another option is specified with the mouse or the tab key.
7c. Dialog boxes typically contain a number of things such as a text box (where information can be typed if neccesary), one of more check boxes (used to click that option on or off), a collapsible list (a down arrow that, when clicked on, reveals a further set of options), and a close button (used to close the dialog box without applying any of the options).
17a. Handling diskettes carefully is important because the magnetically stored data can be very vulnerable to external magnetic forces, dirt, and heat.
17b. Four key points in handling diskettes are:
i. keeping diskettes away from electrical and magnetic devices (anything that generates a magnetic field.)
ii. do not expose diskette to any extreme temperatures
iii. keeping diskettes away from dust, dirt, and moisture.
iv. never touching the diskettes magnetic surface.
20. To write protect a diskette (that is, to prevent it from being overwritten) one has to push up the write protect tab that is on the top left corner of the back of the diskette.
21a. Backups should be created because they prevent the accidental loss of data and take relatively little time to create, when compared with the time required to replace data that can be lost.
21b. It is a good practise to store the backup diskettes away from the originals so that there is little to no chance of both being destroyed at once (prevents from fire, etc.)
