Great things can be done from command prompt mode. It is one kind of Operating System with simple commands like copy paste etc.... It is very useful to format hard disk in MS DOS mode. Installing OS etc.... Trojens and virus can also be operated in this mode. Hacking tools such as telnet, ping, nslookup etc.... are also builtin command prompt.\n\nHope I have answer your Question.

The concept of INTERNAL COMMANDS started back in the DOS days.  Essentially it was a command that could be executed from anywhere in folder structure while at the Command Prompt.  These commands were loaded in the memory by the Command.com loader that initiated at startup.\nThat file has been replaced by cmd.exe in Windows NT/2000/XP/2003 and OS/2\n\nDIR  \nLists the files in the current directory \nCD, CHDIR  \nChanges the current working directory or displays the current directory. \nCOPY  \nCopies one file to another (if the destination file already exists, MS-DOS asks whether to replace it). (See also XCOPY, an external command that could also copy directory trees) \nREN, RENAME  \nRenames a file or directory \nDEL, ERASE  \nDeletes a file. When used on a directory, deletes all files in that directory, but does not recurse or delete the directory itself. \nMD, MKDIR  \nCreates a new directory \nRD, RMDIR  \nRemoves an empty directory \nVOL  \nShows information about a volume \nLABEL  \nShow or change the label of a volume \nVERIFY  \nEnable or disable verification of writing for files \nTYPE  \nDisplay the content of a file on the console \n[edit]\nOther commands\nAll commands from the interactive mode can be used in batch files; similarly, one can use batch-file commands directly on the COMMAND.COM command line, interactively. Therefore, it is impossible to separate the syntax to "interactive" or "batch" commands.\n\nBREAK  \nControls the handling of program interruption with Ctrl+C. \nCLS  \nClears the screen. \nCHCP  \nDisplays or changes the current system code page. \nCTTY  \nDefines the device to use for input and output. \nDATE  \nSet the date of the system. \nECHO  \nToggles whether text is displayed (ECHO ON) or not (ECHO OFF). Also displays text on the screen (ECHO text). \nLH, LOADHIGH  \nLoads a program into upper memory. \nLOCK  \nEnables external programs to perform low-level disk access to a volume. (Windows 95/98/Me only) \nPATH  \nDisplays or change the value of the PATH environment variable which controls the places where COMMAND.COM will search for executable files. \nPAUSE  \nHalts execution of the program and displays a message asking the user to press any key to continue. \nPROMPT  \nDisplays or change the value of the PROMPT environment variable which controls the appearance of the prompt. \nSET  \nSets the value of an environment variable ; Without arguments, shows all defined environment variables. \nTIME  \nSet the time of the system. \nUNLOCK  \nDisables low-level disk access. (Windows 95/98/Me only) \nVER  \nDisplays the version of the operating system. \n\nOn the other hand, EXTERNAL COMMANDS are those not initiated by command.com or cmd.exe, and need to have their entire folder path included for the operating system to find and then execute.

How to use an MS-DOS Prompt window\n\n--------------------------------------------------------------------------------\n\nThe following tutorial is meant as a brief introduction to the MS-DOS Prompt window.\n\nSome of our scripts (such as allposters.pl and gocollect.pl) can be run on your Windows PC. If you plan on doing that, then you must know how to use an MS-DOS Prompt window and you will need to install ActivePerl on your Windows PC. For our other scripts (such as Associate Engine ae.pl), you might need to use an MS-DOS Prompt window to edit or view some files.\n\n\n\nLet's open an MS-DOS Prompt window. To do that, click on the "Start" menu (at the lower left of your screen) and select "Run...". Then type "command" (no quotation marks) into the box and click "OK".\n\n\nYou should see an MS-DOS Prompt window appear.\n\n\nYou tell the MS-DOS Prompt window what you want to do by typing commands rather than using your mouse. The MS-DOS Prompt window understands the commands described in the table below (there are more commands than those listed below). At the end of each command, press the Enter key. To get help on a particular command, add " /?" to the end of the command, such as: "dir /?".\n\nCommand\n Meaning\n \ncls\n Clears the MS-DOS Prompt window and moves the prompt to the top of the window (no files are changed -- the window display is merely cleared).\n \ncd DIRNAME\n MS-DOS works on one directory at a time. The "current" directory is indicated as part of the prompt. For example, "C:&#92;WINDOWS&#92;Desktop>" means that the current directory is the "Desktop" directory which is located inside the "WINDOWS" directory. Use the "cd" command to make a different directory the "current" directory ("cd" is short for "change directory"). For example, "cd &#92;perl" will make "&#92;perl" the current directory. To get to the "root" of your c: drive, type "cd &#92;".\n \ndir\ndir DIRNAME\n "dir" lists the contents of the current directory. "dir DIRNAME" lists the contents of the DIRNAME directory, e.g.: "dir &#92;perl" or "dir mystuff". If you add " /p" to the end of the command, such as "dir mystuff /p", then the output will pause after each screenful and wait for you to press any key (e.g.: Enter).\n \nnotepad FILENAME\n Starts the Notepad text editor program and opens the file named FILENAME. If the file does not exist, Notepad will ask you if you want to create a new file with that name. For example, "notepad allposters.ini" starts Notepad and opens the file allposters.ini located in the current directory. If you want to edit a file that is in a directory other than the current directory, then use the "cd" command first or include the directory name, such as: "notepad &#92;www&#92;allposters&#92;allposters.ini".\n \ntype FILENAME\n Displays on the screen the contents of the file named FILENAME. For example, "type ae.key" displays the contents of the file ae.key located in the current directory. If you want to display a file that is in a directory other than the current directory, then use the "cd" command first or include the directory name, such as: "type &#92;www&#92;ae&#92;ae.key". Note: If the contents of the file is more than one screenful, then you should use the "more" command instead otherwise the text will scroll off the top of the window.\n \nmore FILENAME\n Displays on the screen the contents of the file named FILENAME. For example, "more ae.ini" displays the contents of the file ae.ini located in the current directory. If you want to display a file that is in a directory other than the current directory, then use the "cd" command first or include the directory name, such as: "

It's a command-line based operating system.\n\nIt allows you to control your computer using text commands (like in Unix), rather than a GUI (Graphical User Interface) like Windows.

There are two types of commands in computer - which are used in DOS.\n\nThey are\n* Internal Commands\n* External Commands\n\nInternal Commands are present in the computer itself. They are stored in command.com and whenever you open the dos prompt, you can use these commands. Examples of Internal commands are DIR, MD, CD, etc.\n\nExternal Commands are commands which can be used in DOS but are not present in command.com since their size are larger and they are not frequently used. Whenever they are required, they could be loaded from an outside source like floppy and can be used. Examples are SORT, FDISK, etc.\n\n**********\nVasu M\n**********

No. The prompt is a second chance so-to-speak, so that you don't shut down a critical program like explorer.exe. Shutting down some processes will shut down critcal programs needed to run Windows properly. You can find out more info in the "help and support" section.

CON in the windows command shell is the device handle for the console.  For instance, you can't create a folder or file named LPT1 or COM1 either since those are the device handles for the first parallel and serial ports.
