MS-WINDOWS
Microsoft
developed Microsoft Windows operating system to overcome the limitations of its
on MS-DOS operating system. Windows 3.0 was the first successful version of
this operating system. It was released in 1990. Main features of Microsoft
Windows are as following:
(1)
Its native interface is a GUI. Hence, for a new user it is easier to learn and
use a computer system.
(2)
It is a single-user, multitasking operating system. That is, a user may run more
than one program at a time.
(3)
It allows file names to contain up to 255 characters as well as some
punctuation marks, such as periods, commas, and semicolons.
(4)
Microsoft Windows is not just an operating system, but also a complete
operating environment. That is, all its programs conform to a standard way of
working. For example, a Microsoft Windows word processor works similarly the
way a Microsoft Windows spreadsheet (or any other type of windows program)
works. This means that if a user learns one windows program, this experience is
useful while using any other Microsoft Windows program.
With
these features, Microsoft Windows became an operating system of choice for most
personal computer users after 1990.
Basic Elements of
Opening Screen of Microsoft Windows:
(1) DESKTOP: Desktop is the work area on a windows
screen where you are made to work. It is called the desktop because windows use
your whole screen in a way that is similar to the way you use the top of your
desk. As you work in windows, you move items on the desktop, retrieve and put
away items and perform many other day-to-day tasks.
(2) ICONS AND THEIR
TYPES: An icon is a
graphic object that shows a program or a file on your monitor. The different
types of icons are described below-
System
Icons
System
icons are displayed along left edge of the screen. These objects are created
automatically by windows during its installation. The five system icons are
explained in the following table.
|

|
|
My

icon represents a folder that is used by many programs as a default location
for starting the documents.
|
|

This
icon opens a window displaying the names of each server or computer in your own
work group.
|
|

Control
Panel
|
This
icon provides you to adjust your computer according to your uses. You can

|
Shortcut
Icons
These
are the icons with small arrows in the lower left corner. A shortcut icon
provides easy access to some objects on your system, such as a program, a
document, or a printer, etc. The shortcut icon only contains information about
the location of the object but not the object itself. Deleting a shortcut icon
does not delete the program from the hard disk for that shortcut.
Program,
Folder and Document Icons
These
are non-system icons without arrows and they represent the actual objects they describe.
Thus, if you delete such an icon you are deleting the object itself, from the
hard disk. So be very careful!

explained in the following table.

right corner of the taskbar has the notification area in which windows

such as Volume Control, Network, etc. Other shortcuts can appear temporarily.
For example, the printer icon appears after a document has been sent to the
printer and disappears when printing is complete.

(4) ELEMENTS OF A WINDOW:
Most windows have the
following elements-
Borders:
The four edges
that define the perimeter of a window are called borders. Borders also give a
way to change the size of the window.
Title
bar: Top of the
window is the title bar. It displays the name of the program or the document.
It is also used for moving the window.
Close Button: At the right edge of the title bar is
a square containing an x called the close button. Clicking the close button
closes a document or folder, or terminates a program.
Maximize and Restore
Buttons: Clicking the
maximize button enlarges the window to occupy the whole Desktop. When the
window is maximized, the restore button appears.
Clicking
the restore button causes a window to assume an intermediate size, neither
minimized nor maximized. In this case, maximized button appears.
Minimize Button: Clicking the minimize button reduces
the window to a button on the task bar. Once minimized, the window no longer
takes space on the desktop but the program in it continues to run.
Scroll
Bars, Scroll Boxes and Scroll Buttons: If a window is not long enough to display its contents
completely, vertical scroll bar appears along the right edge. Similarly, if the
window is not wide enough, a horizontal scroll bar appears along the bottom of
the window.
Scroll bars offer an easy way to
navigate through a window with the mouse. They also provide useful information
about the contents of the window.
Scroll bars have small rectangular
boxes called scroll box. The position of this box within the scroll bar tells
you where you are within the window itself. If the scroll box is at the top of
the scroll bar, it means you are at the top of the documents.
Scroll buttons appear along the top
and bottom edges of the vertical scroll bar and along the left and right edges
of the horizontal scroll bar.
Shortcut
Menus: Pressing
the right mouse button brings up a small menu related to the currently selected
object or the one the mouse is pointing to. This menu is at times also referred
to as popup menu. For example, if you right click the taskbar, you get a menu
of commands relating only to the taskbar.
Dialog
Boxes: A Dialog
box will appear when you select a command with an ellipsis(...) after it.
Dialog boxes appear on your screen when windows or its application program you
are using needs more information to execute the command.
