What is MS-DOS?

The operating system which repeatedly takes disk help in its work is called operating system or DOS. DOS can be for all types of computers, small or large. The operating system that Microsoft created for IBM’s personal computers was called Personal Computer-Disk Operating System or PC-DOS.

Later, a company named Microsoft developed the operating system for IBM – PC Compatible computers, it was named Microsoft Disk Operating System or MS-DOS.

Now let’s know what is MS DOS work

Function MS DOS

The following are the tasks automatically performed by MS-DOS

1. Receiving data or commands from the keyboard.
2. Display of results or notifications on VDU.
3. Monitoring the functions of the computer’s hardware (eg – CPU, memory, disk, etc.).
4. Creating space in the memory of programs.

To exercise control over the actions of external devices or means.

Apart from this, there are some such tasks, which can be done in MS-DOS. Some of the main ones are the following
Creating new files, deleting old files, renaming files etc.

1. Creating a list of all files.
2. Formatting the New Floppy Disco.
3. Backing up files from hard disk to floppy.

Structure of DOS

To establish coordination between this operating system and the computer, the following programs are required

Boot Record This is the main program of MS-DOS and loads the operating system into the main memory.

Input/Output System (I/O. SYS) It provides interface between programs and hardware.

MS – DOS.SYS is a set of program routines and data cables that provide high-level programs (for example: application programs).

Command.Com Program
It provides a set of commands to the user, which provides the user with the facility of file management etc.

MS – DOS Prompt

• Once the PC is booted, that is, MS-DOS is loaded into RAM, a symbol appears on the PC’s screen, which is called command prompt or simply prompt.
• C:>
• Here ‘C:’ is the name of the drive from which MS-DOS is loaded, it can also be A, B or D. The symbol (>) is the prompt symbol. Users can also change it as per their wish. After the prompt, there is also a cursor in the form of a small big line, which keeps flickering continuously.
• The VDU appearing on the screen and the cursor blinking means that MS DOS is ready for the next command and when you can type the new command. Each command goes to the PC and its execution starts at the same time.
• After the execution of this command is completed (or it is terminated midway) the prompt comes back on the screen so that a new command can be given.
• or called current drive; For example – if prompt contains C; If so, it means that this time the user will be considered for drive C.
• Example, suppose you have ordered to copy a file, then it will be assumed that the file is in drive C. If the file is not there then it will be useless and the message of file not found will appear on the screen.
• You can also change your current drive. If the user wants to come to drive A, the following command will be given
  C:A: enter
• Here we use this for enter or return. After placing the above order the promotion will be from
  A:>
• Now drive A is your current drive. Sometimes prompt appears as follows
  C:\>

In this, along with the current drive, the name of the current directory is also shown. Here ‘C:’ is the name of the current drive and ‘\’ is the name of the current directory (root directory).

MS-DOS Commands

Tasks are done by giving commands to MS DOS. For each task there is a special order, which also has a definite name.

In fact, these commands are the names of those small programs, which have been written to perform those tasks. For example, the command ‘COPY’ is the name of a program that is written to make a second copy of a file (ie, the exact same file).

The copy command is given to MS DOS to run this program. With each order we provide certain information that is necessary for the execution of that order; For example, with the COPY command, we have to tell under what name to copy the file.

There are two types of MS DOS commands

1. Internal Commands
2. External Commands
