  • Operating System

    An operating system (OS) is software that manages computer hardware and software resources and provides common services for computer programs. The operating system is a vital component of the system software in a computer. Application programs need an operating system to function and are usually designed to work in conjunction with various OS’s. Examples of Operating Systems would be Windows XP, Windows 7 & 8, Linux, Apple Macintosh (iOS or OS X Yosemite)

    For the purpose of this course we will be using Microsoft Windows 7.

    Operating System: Mobile Phones

    Web Depending on how your computer is set up, various items appear on your desktop (known as icons)as seen in the above example. Standard icons on your desktop are:
    • The recycle bin – a temporary storage place for deleted files. Files in the recycle bin can be recovered or permanently deleted.
    • Start or Microsoft Button – situated in the bottom left hand corner of the desktop, when you want to open a program or change system settings or get help to find items on your computer.
    • As stated on the previous page, you can put other icons on your desktop to provide faster access to those programs you use frequently.

    Windows Explorer

    The button to access the Windows Explorer is located on the task bar at the bottom of the screen. The windows explorer allows you to see the contents of the harddrive/flashdrive or any other input devices connected to the pc in a type of tree structure. You can add and remove files and folders and move them around. The icon for the windows explorer is a yellow folder.

    When you open the windows explorer it will look like this:


    1. Close: to close a window, click on the X in the upper right-corner of a window or choose File then Exit
    2. Minimize: to minimize a window, click on the button resembling a minus sign. This minimizes the window off the screen/desktop, but it can be reopened by clicking its button on the Taskbar at the bottom of the screen
    3. Maximize / Restore Down: to maximize a window when it does not fill the whole screen, click on the button with the square, the window will now fill the whole screen. To restore down will resize the window to its previous size
    4. Move: to move a window to another location on the screen, put your mouse pointer on the title bar at the top of the window; click and hold the left mouse button and drag the window to where you want it. When you have reached the desired position on the screen, release the mouse button. Depending on your settings, you should either see the outline of the window as you move the mouse or the window with the contents.

    Web To Resize a window, place the cursor in the lower right corner of the window. When the pointer becomes diagonal arrows, click and hold the mouse button. Drag the mouse to change the size of the window. When it is the right size, release the button.
    NOTE: In Windows 7 windows can snap to certain positions if you move the window to the edge of the screen. This will for example enable you to automatically resize two windows to fit on your desktop, side-by-side.


    The popup window that opens when you open the Windows Explorer can be modified in a number of ways.
    • The actual window itself can be resized, it can either be viewed in full screen although it usually comes up as a popup window. To resize the window move the cursor over the box when it changes from the regular large arrow to a smaller double sided arrow you can click and drag the box bigger or smaller.
    • You can also change the way the files and folders are displayed.
    • The view button is on the tab on the top of the box.
    • The content can be viewed as: content, tiles, details, list, small icons, medium icons, large icons or extra large icons. The image below is set to details, it provides the name of the file, the type of file, the date it was modified and the size of the file. How you set your files depends on what information you want to see. To view image files you may prefer to change your view to medium icons. Regardless of what it is set to, it can always be changed quickly and easily.

    Help Feature

    As we discussed when we looked at the keyboard the F1 key is the help key for most programs including the OS. If you need help with something to do with any part of the operating system simply return to your desktop and press the F1 key. The help dialogue box will pop up.

    There is also a small ‘?’ on the windows explorer box, this also gives access to the help feature. Once you have the help box open you can type in your search criteria and the help box will find the information you require and give you detailed instructions on how to achieve your goal.
