About Basic control in windows XP.

            Most of what you do in Windows XP will be done using a utilities buttons, menus, dialog box or a window. This chapter shows you how you can use these structures.

ñ     Structure of window

All windows are similar in their structure. It is a rectangular frame. As an example we will look at the basic window structure from My Computer window.

Ì    Title Bar

It is located at the top of the window. It contains name of the program, name of file, minimize, maximize, restore and close buttons.

Ì    Maximize

This function allows you to concentrate on on e application by making its window cover the entire screen

Ì    Minimize

This function allows you to keep an application running, but remove it from the desktop area so that other applications can be accessed. The minimized program becomes a bar at the bottom of the screen, and can be accessed by clinking on the bar.

Ì    Resize/Restore

If an application window is not maximized, it can be resized so that more or less contain can be seen. If you move your mouse pointer to one of the edges of the window, it will become a two-way arrow. At

            

This point, hold down the left mouse button and drag the perimeter of the window in our out. When you release the mouse button, the window will resize to your specifications.

Ì    Close 

This function closes and exits the application you are running. However, if you are running an application such as Microsoft word, the window of each document will have a close button, and clicking this button will only close that particular document, and not the entire program, it is important to always save your work before using the close feature, as any unsaved changes will be lost.

Ì    Menu

Most of the  windows will have a menu bar near the top, displaying the menu options relevant to a particular window. Simply click on a menu option to reveal a drop down list of further options within  it. As a n example, we look at the view menu from My Computer window.

Ì    Dialog Boxes

Simple setting can be made from menu options, other setting need to be made from dialog box. Dialog box appear with Tabs, Check Boxes, Radio buttons and Action buttons etc.

Ì    Tab

                                    Click on the appropriate one to display its setting.

Ì    Check Boxes

                     

Click on as many as required. A trick indicates that the option is active. If you click on it again it will be turn off. If an option is dimmed out, it cannot be selected.

Ì          Radio Buttons

                        

                                

   

                        Only one out of group of radio buttons can selected. If you click    another radio button, the previously selected one is automatically turned off.

Ì  Action buttons

OK will save the setting selected and close the dialog box or window. Cancel will close the window without saving the amended setting-click on it if you’ve made a

mistake. Apply will save the setting selected so far but will not close the window, in case you want to make further changes.

As an example we will look at the dialog boxes of bolder option from my computer window.

Ì  Tools Bar

       Tool bar contains the short cut icon of the menu bar. It helps to work with the file directly by clicking icon.

Ì  Scroll Bar

     

  If a window is not big enough to display all the information within it, then a scroll bar will appear automatically. Use it to see the contents of a window not immediately in view.

u  Drag the slider along the scroll bar towards one of the two scroll arrows to scroll in that direction.

u  Click on the scroll bar to display the next window’s amount of information towards the scroll arrow arrested to it.

u  Click on one of the scroll arrows to scroll just a little in that direction. Hold down your mouse button to scroll continuously.

Ì  Resize Pointers.

       If window is not maximized of minimized, it can be resize.

u  Place the mouse arrow anywhere on the edge of a window. It will change to a double header resize pointer.

u  Drag the pointer outwards to increase the size of the window or inwards to reduce the size. Release the mouse button when the window is the desired size.

About Turn Off computer options.

            When this phrase is clicked, the Shut Down menu will appear, allowing you to hibernate shut down, or Restart the computer. To use this feature, refer to the Start Up and Shut Down portion of Level 1.

·                     Stand by

When a computer is left alone for a while, it goes into “sleep” or “stand by” mode to save energy. In stand by mode, the computer slows down its inner processes because they are not  being used. The computer also blacks out the monitor. If

You wish to use a computer and the monitor is dark, check to see if it is in stand by before you try to start it up. Usually the computer has a green light on or near the power button that signifies that it is on, but in stand by mode. To “wake it up,” move the mouse or hit a key on the keyboard. If you do not realize that the computer is in stand by and you try to turn it on with the power button, the computer will wake up and a dialogue box will appear, but it will not damage the computer.

·                     Turn Off

Click here and Windows XP saves any unsaved work before turning off your computer Most newer – type monitors are also turn off automatically.

·                     Restart

This also saves your work and shuts down your computer, but it starts it up again right way Click on this option after making changes to some of  your windows setting and you want these to take effect, or after installing some programs.

·                     Hibernate

Hibernate only appears on some computers. If you don’t see it initially, hold down the shift key and stand by button is replaced by the hibernate button. Its function is similar to the stand by mode, but it also saves whatever is in memory at the time to your hard disk. So when you turn your PC back on, the memory state is loaded automatically on your desktop and open programs appear just as you left them- you can then simply carry on from the point you left off. The Hibernate mode is not as sage as the turn off option so try and avoid using it

    Switch User

·                     Steps to Log Off/Switch User on your Computer

Starting system of computer.

               We know that a computer is simply a machine which works under the control of a set of instructions called program. For a computer to be ready to work, all its peripherals should be checked and activated, and the relationship between hardware and software needs to be established. For this purpose, a special type of software is used, which is called as an Operating System.

            Starting process of computer varies from one operating system to another. There are different processor to enter into the programs. It depends upon the operating system installed into the computer. So, you have to know about operating system of computer before running the programs.

            There are mainly two types of Operating system used in the computer:

1.      Ms. Dos (Microsoft Disk Operating System)

2.      Ms. Windows (Microsoft Windows 3.11, ’95, ’98, ‘Me, ’00, ‘XP..)

However, the inner process of starting your computer is same, which is called Booting.

Booting:

            The process of loading the system files of the operating system from the disk into the computer memory to complete the circuitry requirement of the computer system is called booting. The system files of MS. DOS are:

·         IO.SYS: It checks all the input and output devices and their activities and make them ready

·         MS. DOS.SYS: It builds the relation between the hardware and the application software-acting as interface.

·         COMMAND.COM: It helps to make the instructions given to the computer using the different programs executable.

IOS.SYS AND MSDOS.SYS are hidden files but COMMAND.COM is visible.

Types of Booting:

There are two types of booting:

·         Cold Booting: If the computer is in off state and we boot the computer by pressing the power switch ‘ON’ from the CPU box then it is called as cold booting.

·         Warm Booting: It the computer is already ‘ON’ and we restart it by pressing the ‘RESET’ button from the CPU box or CTRL, ALT and  DEL key simultaneously from the keyboard then it is called warm booting.
