Exploring the Desktop
Jyoti and Tejas were exploring the computer and Moz walks in.
Moz: Hello children. So you are exploring the activities on the Desktop?
Jyoti: Yes. Why is this screen called the Desktop?
 
Moz:  How do you arrange all your books on a desk? If all the books are 
neatly arranged, is it not easy to find them?  In the same way, the screen 
where all the icons are arranged is called a Desktop. Icons of activities that 
we use often are kept on the Desktop. The bar at the bottom of the screen 
is called the Taskbar.

Jyoti double clicks on music icon and then the paint icon.
Jyoti: Two windows have opened. So, can I play music and also paint? 
Moz:  Yes. You can. You can start more than one activity on the computer.
Each time you double click an icon, it opens a new Window for that activity.
Tejas: Clicking on a window brings it to the front.  
Moz: Correct. Whenever you click on a Window, the computer brings it in 
front and allows you to use that activity. 
The top bar of a window is called the Title bar. You can recognize the 
activity in a window by the title on the title bar. 
 
Tejas [Clicks the   button on the title bar of the Paint window]: The 
paint window has gone! How can I get it back?
Moz: You clicked the Minimise 
button. This button is at the top 
right corner and makes any 
window very small. See here on 
the Taskbar. The Paint activity 
window has become a small 
button. Clicking this Paint 
button on the Taskbar will open 
the Paint window again.   
 
The taskbar has one button for 
each window on the Desktop. So, 
all the activities that have been started can be seen in the taskbar.

Tejas is watching the 
windows when Jyoti clicks 
on the Paint window.

the window is used to close the activity. See here, it has gone from the 
taskbar also.
Jyoti: The picture on Tejas's desktop is different from mine.  Can we 
change these pictures?
Moz: Yes. You can.  You can make the desktop look any way you like. The 
picture on the desktop is called the Wallpaper.

Identify the elements of a 
Desktop and Window.
Run multiple activities from the 
Desktop and switch between 
them.
