what is dos?
(OS) is system software that manages computer hardware and software resources and provides common services for computer programs.
how does DOS work.
the DOS computer system interfaces between software programs and a computer’s hardware. When you turn on the computer, the read-only memory (ROM) bootstrap reads the information from the first sector of the hard disk or diskette. Then, it passes control over to it. With the Master Boot Record operating the machine, the computer transfers data from the disk to its read-only memory. Additionally, peripheral devices like monitors and printers also receive information. Then, the computer provides application programming interfaces for programs designed for different operations. They can provide input and output, memory management, program loading, and more.
weaknesses
has a command line user interface therefore it is very less user friendly.
Very few applications are supported in DOS.
It is deprecated by Microsoft that’s why no more updates will be available to MSDOS.
It does not support multitasking. So, only one application can be run on this OS at a time. will run on a much smaller system.
(ENTIRE OS can be placed on a SINGLE MODERN ROM chip!)2.
gives you more "direct" control of the processes.3.
Because of smaller size will "boot" much faster than ANY windows version.4.
Is easier to write "special purpose" programs for, so long as they don't require "fancy" graphics.5.
Allows you to make use of the "old, slow" system you hid in the closet when you bought the "new" one. DOS is very lightweight, and it allows direct access to most hardware.
It does not have the overhead of a multitasking operating system.
