Computer Lessons: THE DESKTOP

Discussion in 'Windows Tools & Tips' started by delfermil30, Aug 20, 2015.

  1. When you first start the computer, and wait for it to finish doing everything, you finally get to the Desktop. The desktop is made up of five sections.

    At this point The Desktop does not matter and will be explained below. What matters here is that you can identify the desktop.
    MOUSE POINTERS

    Mouse Pointers change according to what your computer is doing and/or what you are doing. They are explained towards the bottom of this website page.

    MOUSE POINTERS
    Mouse Pointers are one of the most Helpful things on a computer and yet they go unnoticed. Take this scenario for example:

    Switch Computer ON. Type Password, if you have one. Desktop appears. Double Click on a Microsoft Word 2007 file.

    If you think there is nothing wrong with this scenario you would be mistaken. Why? Because you have to WAIT for the computer to finish running its Start-Up List before you can even consider double clicking on the Microsoft Word 2007 file for example.

    The start-up list is "A list of programs to be launched after the Welcome Screen (Log-In / Password screen) appears but before the Desktop appears". Anti-Virus programs, Printer programs and MS Office are normally in the list. As each program in the start-up list gets launched the Desktop is almost ready to appear. What happens is, one or two programs might launch and finish before the desktop appears. But the other launched programs might have to wait for the desktop to appear before they can finish - Perhaps because they rely on the desktop in some way (i.e. its Screen size) and/or use pieces of the other finished programs in order to work properly. This is why you need to wait for the computer to finish running the start-up list. If you open (double click on) a Microsoft Word 2007 file when the other programs Microsoft Word 2007 relies on have not finished yet (i.e. an Anti-Virus program) you might get problems - For example. You could unknowingly open a virus infected Microsoft Word 2007 file before the Anti-Virus program had chance to scan it. Or you could unknowingly download a virus infected file from the Internet, turn off (shutdown) the computer as normal, start it the next day and then unknowingly open the virus infected file. All because you could not wait a short time for the computer to finish processing its start-up list.

    The normal time to wait for the computer to finish processing the start-up list, after the Desktop has appeared, is between 30 seconds and 1 minute (Pentium 3 or 4) but no more than 2 minutes (Pentium 2).

    Unfortunately, Microsoft have not put a "I am ready" message on the computer when the start-up list has finished. Simply because how would they know? A program can run in the Background, which means the computer does not wait for it to finish before running the next program. Instead it allows all programs to run at once - To speed things up. This is why the desktop appears after the first set of start-up list programs but before the final set of start-up list programs. As each program finishes the mouse pointer usually turns into the Busy Pointer, to denote a program is busy finishing, before it turns back into the Standard Pointer. Here is an explanation of each mouse pointer:

    Precision pointer - This mouse pointer is used for Drawing. It allows you to use pinpoint (pixel) precision when Line Drawing for example.

    Unavailable pointer - Indicates that the action you are trying to do is forbidden.

    Vertical Resize pointer - Used when you are vertically (up / down) resizing a window for example.

    Horizontal Resize pointer - Used when you are horizontally (left / right) resizing a window for example.

    Diagonal Resize pointer - Used when you are diagonally (top-left / bottom-right) resizing a window for example.

    Diagonal Resize pointer - Used when you are diagonally (top-right / bottom-left) resizing a window for example.

    Move pointer - Moves an object around. The object could be a Selected Drawing for example.

    THINGS TO REMEMBER

    • A Click - Press the Left (or Right) Mouse Button once.
    • A Double Click - Press the Left (or Right) Mouse Button twice, quite fast, on the same spot.
    • Highlight means to make an Icon or Menu-Item turn blue only
    • Select means to activate a menu-item's command (i.e. Empty Recycle Bin) or to launch (execute/run) the software associated with the icon.
    • Placing the Mouse Pointer over a Menu-Item highlights that menu-item only.
    • Placing the Mouse Pointer over a Menu-Item and then clicking highlights and then selects that menu-item. The software associated with that menu-item is then launched (executed/run).
    • Placing the Mouse Pointer over an Icon and then clicking on it highlights that icon only.
    • Placing the Mouse Pointer over an Icon and then double clicking on it highlights and then selects that icon. The software associated with that icon is then launched (executed/run).
    • Clicking the Right Mouse Button, whilst the mouse pointer is over a menu-item or icon, displays a Menu (if the software supports this function).
    • Mouse Pointers can help you detect when the computer is busy running software, perhaps in the Background.
    • Wait for the computer to finish running all of the Start-Up List software before continuing.
