what is the 1st operating system in the world.?

Answer 1

The first computers did not have operating systems. By the early 1960s, commercial computer vendors were supplying quite extensive tools for streamlining the development, scheduling, and execution of jobs on batch processing systems. Examples were produced by UNIVAC and Control Data Corporation, amongst others.

Through the 1960s, several major concepts were developed, driving the development of operating systems. The development of the IBM System/360 produced a family of mainframe computers available in widely differing capacities and price points, for which a single operating system OS/360 was planned (rather than developing ad-hoc programs for every individual model). This concept of a single OS spanning an entire product line was crucial for the success of System/360 and, in fact, IBM's current mainframe operating systems are distant descendants of this original system; applications written for the OS/360 can still be run on modern machines. OS/360 also contained another important advance: the development of the hard disk permanent storage device (which IBM called DASD). Another key development was the concept of time-sharing: the idea of sharing the resources of expensive computers amongst multiple computer users interacting in real time with the system. Time sharing allowed all of the users to have the illusion of having exclusive access to the machine; the Multics timesharing system was the most famous of a number of new operating systems developed to take advantage of the concept.

Multics, particularly, was an inspiration to a number of operating systems developed in the 1970s, notably Unix by Dennis Richie and Ken Thompson. Another commercially-popular minicomputer operating system was VMS.

The first microcomputers did not have the capacity or need for the elaborate operating systems that had been developed for mainframes and minis; minimalistic operating systems were developed, often loaded from ROM and known as Monitors. One notable early disk-based operating system was CP/M, which was supported on many early microcomputers and was largely cloned in creating MS-DOS, which became wildly popular as the operating system chosen for the IBM PC (IBM's version of it was called IBM-DOS or PC-DOS), its successors making Microsoft one of the world's most profitable companies. The major alternative throughout the 1980s in the microcomputer market was Mac OS, tied intimately to the Apple Macintosh computer.

By the 1990s, the microcomputer had evolved to the point where, as well as extensive GUI facilities, the robustness and flexibility of operating systems of larger computers became increasingly desirable. Microsoft's response to this change was the development of Windows NT, which served as the basis for Microsoft's desktop operating system line starting in 2001. Apple rebuilt their operating system on top of a Unix core as Mac OS X, also released in 2001. Hobbyist-developed reimplementations of Unix, assembled with the tools from the GNU Project, also became popular; versions based on the Linux kernel are by far the most popular, with the BSD derived UNIXes holding a small portion of the server market.

The growing complexity of embedded devices has led to increasing use of embedded operating systems.




So OS/360 is the first operating system that was developed.

Answer 2

First Operating System

Answer 3

Hi there.

Well, there are many school of thoughts about who was the first to create the first operating system.

They ranged from:

1) DOS (actually QDOS 0.10 - Quick and Dirty Operating System) originally by Seattle Computer (later acquired by M$).
2) CP/M, for Control Processor Monitor (was considered the first operating system for a personal computer) by Gary Kildall of the Naval Postgraduate School in Monterey, California
3) IBM

Many argue it was CP/M was the first. The debates continues till today.

Hope this helps

Answer 5

1st operating system world

Answer 6

DOS was the first operating system to my knowledge that allowed work T0 be saved and read from disks (Disk Operating System)
commodore basic was not an operating system

Answer 7

CP/M (Control Program/Monitor or Control Program for Microcomputers)

In 1974, Gary Kildall founder of Digital Research Inc. created the CP/M program for microComputers. Originally implimented for Intel 8080/85.

Gary Kildall died on July 8, 1994, of blunt force trauma to the head.

Answer 8

MIT Operating system

Answer 9

Microsoft Windows XP

Answer 10

Yes. Windows 3.1 is known for its awesome 3d gaming and up to date accelerated graphics. Your 486 should have no problem with world of warcraft.
