History of Operating Systems

History of Operating Systems 

Operating systems have changed over the years. In the 1950s, computers could only do one thing at a time, like a basic calculator. But as time passed, computers started getting more software programs, kind of like libraries, which eventually led to today's operating systems.

The very first operating system was made by General Motors in 1956 for an IBM mainframe computer called the IBM 704. IBM was the first company to create and include operating systems in its computers during the 1960s.

Here are some key points about operating systems:

1. In the late 1960s, Stanford Research Institute developed the oN-Line System (NLS), which looked a lot like the desktop operating systems we use today.
2. Microsoft bought something called QDOS (Quick and Dirty Operating System) in 1981 and called it Microsoft Operating System (MS-DOS). By 1994, Microsoft had stopped supporting MS-DOS.
3. Unix came about in the mid-1960s, thanks to a collaboration between MIT, AT&T Bell Labs, and General Electric. At first, it was called MULTICS.
4. FreeBSD, another version of Unix, started as a project at Berkeley. The modern Macintosh computers use a modified version of FreeBSD for their operating system (OS X).
5. Windows 95, released in 1995 by Microsoft, was a user-friendly operating system that relied on MS-DOS. It was part of the Windows 9x family.
6. Solaris is a special Unix operating system created by Sun Microsystems in 1991. After Oracle bought Sun in 2010, it became known as Oracle Solaris.
