DOS Operation System

COMPUTER CONTROL 2
DOS MEANING USES?
1) A DOS, or disk operating system, is an operating system that runs
from a disk drive. The term can also refer to a particular family of disk
operating systems, most commonly MS-DOS, an acronym for
Microsoft DOS.
2) The purpose of a disk operating system is to enable the computer to
transfer the data stored on a magnetic disk to another part of the
computer: its main memory, known as RAM (Random Access
Memory), the video screen or the printer.
Dos Development..
 MS-DOS originally written by Tim Paterson and introduced by
Microsoft in August 1981 and was last updated in 1994 when MSDOS 6.22 was released.
 In 1981, IBM licensed and marketed its
PC-DOS rebranding of MS-DOS to run on
IBM PCs. MS-DOS was released for x86
computers, went through eight major
versions and was ultimately retired from
all active support in 2006.
WHY MS-DOS IS USED?
 MS-DOS allows the user to navigate, open, and otherwise
manipulate files on their computer from a command line instead
of a GUI like Windows. Today, MS-DOS is no longer used; however,
the command shell, more commonly known as the Windows
command line is still used by many users.
IS MS-DOS A LANGUAGE?
 DOS commonly refers to “disk operating system.” An operating
system is not a programming language. An operating system might
or might not come with a programming language included (e.g.,
various batch and scripting languages, a BASIC interpreter, etc.).
WHERE WAS MS-DOS DEVELOPED?
 Seattle Computer Products
 American computer programmer Timothy Paterson, a developer
for Seattle Computer Products, wrote the original operating
system for the Intel Corporation's 8086 microprocessor in 1980,
initially calling it QDOS (Quick and Dirty Operating System), which
was soon renamed 86-DOS
HOW TO OPEN MS-DOS IN WINDOWS?
1)
2)
3)
4)
Step 1: Click on Windows.
Step 2: Search for 'Run' or directly use (Windows key+R) to open.
Step 3: Type 'cmd' in run and press 'Enter'.
Step 4: MS-DOS will open in many cases with default command
prompt i.e. c:\>
HOW MANY COMMANDS ARE IN MS-DOS?
 According to different versions of Microsoft, there are about
100 MS-DOS commands. Here we will give you the MS-DOS
commands and their description: Date Command: This Command
aims to change or/and display the current system date. TIME
Command: This Command aims to change or/and display the
current system
WHAT ARE THE DOS COMMANDS USED
FOR?
 The dos command is used in the CONFIG. SYS file to specify the
memory location for DOS. The doskey command is used to edit
command lines, create macros, and recall previously entered
commands. The dosshell command starts DOS Shell, a graphical file
management tool for MS-DOS.
IS DOS USED NOW?
 Continued use
 As of 2023, available compatible systems are FreeDOS, ROM-DOS,
PTS-DOS, RxDOS and REAL/32. Some computer manufacturers,
including Dell and HP, sell computers with FreeDOS as an OEM
operating system. And a few developers and computer engineers
still use it because it is close to the hardware.
IS DOS BETTER THAN WINDOWS
 Windows is a more modern and feature-rich operating system
compared to DOS and is better suited for modern computing
devices. However, DOS is still used today in some legacy systems
and applications that require a command-line interface
 The execution of tasks is slower in DOS as compared to windows.
In windows the execution of tasks is faster. 10. In DOS, we can only
use one window at a time.
WHEN DID MICROSOFT STOP USING DOS?
 Microsoft announced they'd no longer support MS-DOS in 1994.
Everything on the consumer front was about graphical user
interfaces, thanks in large part to Apple. (Some would say that
Apple had stolen the graphical user interface from Xerox, but
that's a story for another time.
WHAT ARE THE DISADVANTAGES OF DOS?
 One major disadvantage is that MS-DOS is not compatible with
newer software and hardware, so it may not be able to run certain
programs or access certain devices. Furthermore, MS-DOS lacks a
graphical user interface, which can make it difficult to navigate for
those accustomed to modern operating systems.
WHAT ARE THE ADVANTAGES OF DOS?
1) One of the most significant benefits of DOS is its simplicity. With DOS, you don't
need a fancy graphical user interface (GUI) to operate your computer. Instead,
you can use a command-line interface, which means typing commands in plain
text to perform tasks.
2) DOS-based systems were widely used in the 1980s and early 1990s, and if
you're a fan of retro technology, you can still experience that era with DOS. You
can run older software programs and games that were designed to run on DOSbased systems, such as classic titles like Doom or Commander Keen.

If you're interested in trying out some old-school DOS games, check out DOSBox, an open-source emulator that
allows you to run DOS programs on modern computers.
3) DOS can be a powerful tool for programming and development purposes. The
command-line interface provides a direct and streamlined way to execute
commands and run scripts, making it ideal for programmers who need to
automate tasks quickly and efficiently.
4) To get started with DOS programming, you can use a text editor like Notepad to
write batch files, which are scripts that execute a series of commands
automatically. Batch files can be used to automate repetitive tasks, such as
renaming files or backing up data.
5) Have you ever experienced a computer crash or had a hard drive become
corrupted, resulting in the loss of important data? It can be a frustrating
and stressful experience. However, DOS can help you recover data from
damaged or corrupted hard drives.
6) To recover data using DOS, you'll need to boot your computer from a DOS
disk or USB drive. Once you're in DOS, you can use commands like "dir"
and "copy" to navigate the file system and copy files to a safe location
