Introduction to DOS


Q) What is DOS?
A) In simple terms, a disk operating system provides a predictable linkage (one following established rules) between your computers electronic circuitry (hardware) and the software programs you use, such as word processors, electronic spreadsheets, database managers, and accounting programs.


In addition to providing the software-to-machine interface, DOS features a host of handy "housekeeping tools" For example, there are special utilities for preparing new disks, listing the contents (or filenames) of a magnetic disk on the display screen or to your printer, creating, copying, deleting, and combining files, and much more.
These features are described in this blog. Visit This Link 

The DOS program is sophisticated; it often appears intimidating because its commands are cryptic. DOS does not display a series of friendly menus or user messages. To the contrary, it displays a letter and a blinking cursor. Although it is not apparent, this is the DOS prompt, where a prompt invites you to type a command from the keyboard.

Therefore, it is necessary for you to memorize a few fundamental DOS commands, where commands are typed instructions recognized by DOS. English-speaking countries are fortunate, because most DOS commands displays a directory (or list) of filenames on the screen. The FORMAT command is used to format (or prepare) a new magnetic storage disk for use with your microcomputer.

DOS stays out of your way unless you call on it by entering one of its special commands. Of course, you can ignore DOS by running package applications programs that contain all necessary DOS strongly recommended if you are to exploit the full power of your microcomputer.

You can do useful things by leaning a half-dozen or so commands. The more you use DOS, the richer it becomes. After a brief exposure, you will begin to feel like a veteran computer user, because the utility of DOS lets you get down to the nuts and bolts to file creation and management.

FORMAT

The FORMAT  command prepares a new disk for use by organizing the disk into magnetic tracks and sectors that are readable by DOS. when a disk is formatted, any files on that disk are usually lost. because of the plethora of disk types and capacities, new parameters were added to the FORMAT command in DOS  version 4.01. MS-DOS 5.00 introduction a safe FORMAT command and the ability to UNFORMAT unintentially formatted disks. These parameters and others are presented in the following paragraph and table. FORMAT Command Form:   There are a number of FORMAT command forms. These are described in the following list. CAUTION  BE aware that the FORMAT command erases all files from the disk being formatted.     Many computer users  have accidentally formatted the wrong disk. If you have programs or    document files  you wish to keep, do not format the disk! (DOS 5.00 lets you UNFORMAT     disk, but even with this ve...

Making, Changing, and Removing Directories

You used the DIR (directory) command in Section 3 to display a list of filenames on the screen. You can create and name multiple disk directories on a disk to allow for the subdivision of your files. This feature lets you group common files into separate directories. This is similar to subdividing information into file cabinet drawers and file folders. This is particularly convenient when you use a fixed disk containing hundreds or even thousands of files. Instead of listing all files in one directory, you can list files in smaller, more manageable sub directories. Lock at the following directory commands. Command                                      Purpose                   MKDIR or MD                                Make a new directory        ...
