How do you resizing the DOS Prompt in Windows 7?

Its a simple way to resizing the cmd prompt in Windows 7 for 32 bit operating systems.

Just open the cmd prompt by typing the text cmd on search bar on Start menu.

If you press Alt+Enter, that will notice an error that "This system doesn't support full screen mode"

I'm giving a solution here.

Right click on the Title bar of the cmd Prompt window and select the properties menu. It show tabs as Options, Font, Layout, Colors.

Select Layout tab.

Here deselect the Let system position window option. Then increase the width and height of the Window size option.

I am also giving you my default full screen setting.

Set Width as 133 and height as 42 in Window Size,

Set Width as 165 and height as 500 in Window buffer size,

Set Left as 0 and top as 3 in Window position.

Is a MS-DOS a single tasking operating system?

Yes, but since it allows you to run software which utilises all of the processor you can run programs that makes it possible to multitask.

Windows 3.x, Novell NetWare and DOS extenders such as DOS4GW are some examples.

That might be called "running another OS on DOS".

What three commands may be used to leave the global configuration mode and return to the privileged exec mode?

Router#Disable

Router >

I don't know the second.

Update: Disable is the only command I believe. However, looking at an Instructors copy of the lab (for 11.5.1), it lists the answers as: exit and end. So I guess they meant to ask "which two commands may be used to leave global configuration and RETURN to privileged exec mode". Hopefully it's worded correctly on an exam!

How do you display the contents of a text file in command prompt?

DOS (Windows):

TYPE

Displays the contents of a file on the screen. If you use this command on a file which is not a text file, the display will be unintelligible. Use with "|MORE" to display the text on a page by page basis, and prevent it scrolling off the screen. "|" is a pipe character.

LINUX:

cat

less

this are commands (programs) that let you view text files, less is like cat, but if the files are so long that they don't fit on your screen,less automatically paginates the file. You use less by giving the file name as an argument to it:

less filename.txt

You use cat in the same way by giving the file name as an argument to it:

cat filename.txt

What is ms dos explain any 5 internal dos command?

MS DOS is Microsoft Disk Operating System. It was a command-line interface, meaning the user had to type in commands to use it, unlike Windows which is a Graphical User Interface. MS DOS was released on IBM PCs when they came out in the 1980s and continued in popular use until the mid 1990s, by which time the first of the Windows operating systems, Windows 95, began to take over.

MS DOS commands were either stored as individual programs, known as external commands, or in a file called Command.com, which stored more commonly used commands. These were called internal commands. Included in these would have been commands like COPY, DEL, DIR, CD and RD.

COPY enabled the copying of files. DEL deleted files. DIR gave a listing of files in a directory (now called a folder). CD changed from one directory to another. RD removed a directory.

All files, DOS, or Windows have attributes. Files can be Hidden, System, Read-Only, Archive, or any combination of them. For example, there are some important windows files that are hidden, read-only, and system.

On a windows operating system, you can right-click the file, and choose properties from the menu. At the bottom, you should see the attributies of a file.
