▪  The Desktop is the on-screen work area on which windows appear, it’ s the first screen that appears when the operating system has initialized. In our case it will be the Windows XP desktop.

 

Components of the Desktop:

desktop

 

Shortcut Icons

▪  Icon is a small picture on the screen representing. An object, an. object may be an application or folder. Shortcut icons allow quick access to commonly used programs, folders or documents.

▪  Shortcut icons contain an arrow at the bottom of the picture.

▪  Icons help you execute commands quickly.

 

Start Button:

▪  It allows access to various menu commands.

▪  It is used for starting a program, find a file, or get help. All application are accessible through the start button.

 

Date and Time Area:

▪  It displays the current time from the internal clock. It provides other status information about the system like print status, volume status.

 

Quick Launch Icons:

▪  It shows all the application in the form of boxes

▪  Quick Launch icons are used to execute a command quickly.

▪  What-ever applications are frequently used, keep it in quick launch icon area so that when-ever need you can open it quickly.

▪  Icons help you execute commands quickly

Task Bar:

taskbar

 

At the bottom of the Windows screen, it contains the Start button, icons for open applications, the Quick Launch area, and the notification area or Date and Time Area.

▪  The long horizontal bar at the bottom of the screen is called the taskbar.

▪  It shows all the application in the form of boxes.

▪  It allows shifting from one application to another

▪  In the graphical user interface (GUI) for a computer operating system or application, a taskbar is a visual device on the desktop that typically shows the user which applications (tasks) are currently active and running. Some taskbars, such as those in Windows operating systems, also include icons for commonly-used utilities such as the system clock and antivirus software. In some systems, the user is allowed to modify the contents, location, or appearance of the taskbar.

After that, you can right-click any one of them and get your context menu.

It looks like this:

Here different .drivers and different directories are at left side. Selecting proper drive and directory at right panel can get list of file directory.

▪  The Explorer is an indispensible tool in an operating system, since with it we can organize and control the files and folders of the different storage systems at our disposal such as the hard drive, disk drive, etc.

▪  The Windows Explorer is also known as the File Manager. Through it we can delete, see, copy, or move files and folders.

▪  We suggest you pay particular attention to this unit because of its great importance.

 

Coping, Deleting and Renaming files and folders.

All of these tasks are straightforward and can be achieved using the same method. First, navigate to the folder where the file or folder is stored, and then right click on the file/folder of interest. You. Will be presented with a menu similar to that showing on below fig-

(3)   Then select the destination

(4)   Either choose Paste from the Edit menu or press Ctrl+V (Windows)

What are hidden file ?

▪  Hidden files are those files that are not listed with DIR.

▪  Some application programs create hidden files. DOS also creates hidden files when it formats a disk with the /s option.

▪  ATTRIB, an external DOS command, can be used to find out if there are any hidden files in any directory.

▪  For example, ATTRIB C:\*.* displays attributes for all .files in the root directory of drive C. If DOS displays “H” against a
file name, it indicates that file is hidden.

 

What is the use of autoexec.bat file ?

 

▪  AUTOEXEC.BAT is a special batch file that is run automatically when DOS starts.

▪  In the filename AUTOEXEC.BAT, ‘AUTOEXEC’  stands for automatically executable and ‘BAT’ stand s for the batch file.

Method 2

▪  Click Start, point to Programs, and then right-click the program you want to create the shortcut to.

▪  Click Create Shortcut.

 

Write a note on Recycle Bin.

 

▪  Recycle bin is an area in the hard disk for storing deleted files.

▪  Recycle bin is available on the desktop, or in the explorer.

▪  Any file or folders, which have been deleted in Windows 95/95 is stored in the recycle bin.

▪  The purpose of recycle bin is to restore files which have been deleted.

▪  Recycle bin has a pre-set size, which defined the number of files it can store. When the recycle bin is full, it deletes earlier files automatically.

 

Restoring deleted file from the recycle bin:

1.  Double click the recycle bin icon on the desktop.

2.  Click the right mouse button of the file to be recovered.

3.  Select the restore option from menu.

 

Empting the recycle bin

1. Click the right mouse button on the recycle bin icon and select the
“empty recycle bin” command.

Allocating space to the recycle bin:

  1. Click the right mouse button on the recycle bin icon, and select the
    properties option.
  2. Drag the space together, to denote the space required.

recycle bin

 

It has reserved 10% of total hard disk capacity for the Recycle Binby default. Ten percent might be considered very huge if based on today’s huge hard disks. For instance, on a 100GB hard disk, 10% works out to be 10GB. A total of 10GB reserved space for Recycle Bin might be too huge.

DOS Commands

▪  Commands are the way of communicating with computers.

▪  Anything we want the computer system to do is told in the form of commands in the predefined syntax.

 

DOS has two types of commands: –

1) Internal Commands 2) External Commands

Internal commands: –

An Internal command, which is a command embedded into the command.com file, these are those commands for which the code for executing them is stored in COMMAND.COM and they execute without the requirement of any other file. When an internal command is issue by the user, the transient portion knows what to do & executes that command.

External commands: –

External command, which is not embedded into command.com and therefore requires a separate file to be used. These are the independent executable files that can be used as separate utilities also.
Information about these files is also stored in the transient portion. When an external command is issued, the transient portion picks up the relevant file of that command &
executes it.

INTERNAL COMMANDS

  1. 1.      TIME

Displays current time and allows it to be changed.

Difference between copy and diskcopy

COPY

DISKCOPY

The copy command is used to copy all the files only it will not copy files from the sub directory and it will not copy any folder also The diskcopy command is used to copy the complete contents of a diskette to another diskette; i.e. it makes a duplicate diskette.
Before overwriting copy command will prompt the conformation massage. DISKCOPY destroys all contents on the target diskette without giving you ant warming. To avoid mix-up of source and target diskettes, always write-protect the source diskette.

 

Difference CD\ and CD..

CD\

CD..

Used to go to root directory Used to go to previous directory means goes back one directory.
Before overwriting copy command will prompt the conformation massage. DISKCOPY destroys all contents on the target diskette without giving you ant warming. To avoid mix-up of source and target diskettes, always write-protect the source diskette.
Eg.C:\Windows\COMMAND>cd\

Result : C:\>Eg.C:\Windows\COMMAND>cd..

Result : C:\Windows>

 

Difference del and rd

DEL

RD

Delete one or more files from the current directory Remove current directory, this command will only work if the folders are empty.
