DOS
DOS is a kind of CUI OS (Character User Interface Operating System) in which the user sends commands and
instructions to the Computer in character form i.e., by typing commands at the command prompt. The display
on the screen does not contain any graphics or pictures.
DOS was the first operating system used by IBM-compatible computers. It was originally available in two
versions that were essentially the same but marketed under two different names. ‘PC-DOS’ was the version
developed by IBM and sold to the first IBM-compatible manufacturers. MS-DOS was the version that
Microsoft bought the rights to and was bundled with the first version of Windows.
Microsoft Windows
Windows is one of the most popular series of operating systems developed by Microsoft Corporation. Each
version of Windows includes a graphical user interface ( UI), with a desktop that allows users to view files
and folders.
In Windows, the user doesn’t need to remember all the commands but needs to recognize the graphical
representation of the application on the screen in order to use them. Windows 7 has a Graphical User
Interface (GUI) which means you do not have to remember all the commands. It allows you to run several
programs at the same time.
The ease of its use has made Windows a very popular Operating System among users. Windows 8 in 2012
offered a ‘Start’ screen with applications appearing as tiles on a grid and the ability to synchronize settings,
so users could log on to another Windows 8 machine and use their preferred settings. In 2015, Microsoft
released Windows 10, which came with Cortana, a digital personal assistant like Apple’s Siri and the Web
browser Microsoft Edge which replaced Internet Explorer.
Among all its versions, Windows 11 is the latest version of the Windows Operating System released on
October 5, 2021.
