OPERATING SYSTEM

TIMELINE

1954: MIT's Tape director operating system made of for UNIVAC 1103

 

1956: The GM-NAAI/O input/output system of General Motors and North American Aviation was the first operating system for the IBM 704 computer.

1960: IBSYS was the tape-based operating system that IBM supplied with its IBM 7090 computer. It was really a basic monitor program, that read control card images and data cards of individual jobs.

1964: The Berkely Timesharing System was a pioneering time-sharing operating system implemented between 1964 and 1967 at the University of California Berkely.

1966-DOS: Disk Operating System/360, also DOS/360, or simply DOS, was an operating system for IBM mainframes. It was first delivered by IBM in June 1966. In its time DOS was the most widely used operating system in the world. 

Initial releases of DOS could run only one program at a time. Later version of "real" DOS were able to run up to three programs concurrentrly. 

 1969-UNIX: Unix is a multitasking, multi-user computer operating system that exists in many variants. The original Unix was developed at AT&T's Bell Labs research center by Ken Thompson. Dennis Richie. From the user's perspective, Unix system are characterized by a modular design that is sometimes called the "Unix philosophy," meaning the OS provides a set of simple tools that each perform a limited, well-defined function with a unified filesystem and a shell scripting and command language to perform complex workflows.

1981-IBM PC DOS: IBM PC DOS (full name: IBM Personal Computer Disk Operating system) was an operating system for the IBM Personal Computer, manufactured and sold by IBM from the 1980s to the 2000s.

1984-MAC OS: In 1984, Apple Computer Inc. introduced the Macintosh personal computer, with the Macintosh 128k model, which came bundled with what was later renamed to Mac OS. After hearing about the pioneering GUI technology being developed at Xerox PARC from former Xerox employees, jobs negotiated a visit to see the Xerox Alto computer and Smalltalk development tools in exchange for Apple stock options. The Macintosh operating system used concepts form the Xerox Alto, but many elements of the graphical user interface were created by Apple including the menu bar, pop-up menus, and the concepts of drag and drop and direct manipulation.

1985-Windows 1.0: Microsoft Windows 1.01 retails, at a list price of $99. It's marketed as a graphical user interface that extends the DOS operating system and lets users run several programs at the same time freely switch among them. But it's not touted as an actual operating system until a decade later.

 

1991-Linux: Norse OS god Linus Torvalds releases an open-sources, Unix-like OS kernel that sort of bears his name. Linux is officially pronounced "leen-ooks" to reflect its Finnish origins. The Linux kernel will subsequently be combined with GNU software to create an array of open-source operating systems known as Linux distributions. 

1995-Windows 95: Windows 95 appears, to great fanfare. It spawns a new line of Microsoft operating system with one foot in the 32-bit world and another stuck in the mud with not-yet-obsolete 16-bit software.

1996-Windows NT: Windows NT 4.0 is a preemptive, graphical operating system. designed to work with either uni-processor or symmetric multi-processor computers. It was a part of Microsoft's Windows NT line of operating system.

It is a 32-bit Windows system available in both workstation and server editions with a graphical environment similar to that of Windows 95.

2000-Red Hat Linux: Red Hat Linux, assembled by the company Red Hat, was a popular Linux based operating system. It was the first Linux distribution to use the RPM Package Manager. For a system administration performing software installation and maintenance, the use of package management rather than manual building has advantages such as simplicity, consistency and the ability for these processes to be automated and non-interactive.  

2007-IOS: IOS (previously iPhone OS) is a mobile operating system developed by Apple Inc. and distributed exclusively for Apple hardware. It is the operating system that powers many of the company's iDevices, including the iPad, iPod Touch and Apple Tv.

2007-Android: Android is a mobile operating system (OS) based on the Linux kernel. developed bu Google. With a user interface based on direct manipulation, Android is designed primarily for touchscreen mobile devices such as smartphones and tablet computers.

2011-Mac OS X Lion: It is the eighth major release of Mac OS X, Apple's desktop and server operating system for Macintosh computers. There are Over 250 new features including: Address Book uses an iPad-like user interface, Auto-Save. Air Drop-direct file sharing via WI-Fi Direct. Face Time, Apple push Notifications Services, etc.

2012-Windows 8: Windows 8 is a personal computer operating system developed by Microsoft as part of Windows NT family of operating system. Windows 8 introduced major changes to the operating system's platform and user interface to improve its user experience on tablets.

Windows 8 also adds native support for USB 3.0 devices, which allow for faster data transfers and improved power management with compatible devices.
