What is the history of the windows operating system and MSDOS?
In the year 1985, the operating system Windows was released by Microsoft. In the beginning, Windows was just a Graphical User Interface in its first version. Windows 1 is the name of the first version of Windows which was released in the year 1985.
The purpose of Windows was to let people interact with the machine with a Graphical User Interface without using codes even for all purposes, even for starting a system.
The three latest versions of windows are Windows 10 Home, Windows 10 Pro and Windows Enterprise.
The Windows operating system manages the process with the help of a function which is named as CreateProcess with the help of which a process is created which includes a not more than a thread. The function CreateProcess is called the name of the file which is an executable file.
The Windows operating system manages the memory by processing a process in which an environment of demand paged virtual memory under which if an application starts then the entire application will not be loaded into the memory.
The Windows operating system allows the users to manage the devices according to them through the control panel in the Graphical User Interface. If any hardware or a device which is connected with the system is failing or not working then the operating system will inform the user about the failure.
History and development of MS-DOS
The initial name of MS-Dos was 86-DOS and it was owned by Seattle computer products.This OS was written by an American computer programmer Tim Patterson.
He could complete the making of 86-DOS within six weeks, as it was primarily a clone of Digital Research’s. This was a company which mainly marketed and developed CP/M Operating System Control program/Monitor (CP/M). This system was ported to run on 8086 processors.
Microsoft required an OS for IBM personal computer, so they hired Patterson to Microsoft in 1981 and bought 86-DOS for $75000. Later on, Microsoft started to put versions to it and renamed 86-Dos as Ms-Dos.
Features of MS-DOS
Some of the features those are distinct in the MS-DOS from other operating systems are as follows −
GUI or Graphical User Interface does not support Ms-Dos. We have to type some reserved commands to do any operations. Moreover, it is a character based interface system.
Unlike windows 10 or any latest operating systems ms-dos does not support multitasking. In other words, it allows running only one application at a time. Hence, it is a single user OS.
The drawbacks in the MS-DOS are as follows −
No multitasking facility.
Not all people can operate the system very easily.
Difficulty in memory access when it has more than 640MB RAM.
Interrupt level for hardware has to be managed by the user itself.
Note − Operating Systems like Mac and Ubuntu can contribute the characteristics of msdos in many ways. Because these are GUI based operating systems and it supports multi-tasking and advanced memory storage compared to ms-dos.
