Then came UNIX support (MVS/SP V4.3) and the MVS operating system was then developed to add support for the UNIX-like POSIX version of the Portable Operating System Interface standard. From ESA, the MVS operating system was developed to OS/390 then to z/OS which added 64-bit support. There have been many extensions given to the MVS operating system, including MVS/SE (System extension) through MVS/XA (Extended Architecture) to MVS/ESA (Enterprise Systems Architecture) with some in between these variations. Developed in 1974, this OS is still being used, but gradually being replaced with a more modern operating system. The older IBM mainframe computers used the MVS Multiple Virtual Storage operating system. It exploits the virtual memory concept, and was used on the VAX computer – now no longer made, but with some models still in use. Because this OS can be distributed over several different machines, individual machine breakdowns, which might cause significant disruption of individual data-processing units, have less of an effect on corporate computers using VMS.Įven though it is 30 years old, clients who use it believe that it will last for eternity.

It is designed to handle time sharing, and batch and transaction processing, which makes it an ideal operating system for businesses such as Amazon. This is not surprising due its ability to handle multi-users and multi-processing operations.

It is now generally known as Open VMS, and is used by Amazon, the Deutsche Borse and the Australian Stock Exchange. Open VMS: Virtual Memory Systemĭesigned for microcomputers and workstations, the VMS virtual memory system is a multi-tasking OS for multiple users that was launched in 1979 along with the VAX Minicomputer. Nevertheless, for anybody focussing on the cloud, Solaris could be a good choice of OS on which to write cloud-based software. Solaris runs on Oracle’s SPARC servers, which, while set to run at least until 2019, may not have much of a future beyond that if Oracle’s server income slides.

An interesting development when first released, Linux is now used widely by developers who, under the open-source system, can make changes to the software to meet their own needs.

Linux Operating SystemĪs stated above, Linux was derived from UNIX – derived by Swede Linus Torvalds and released to the public in 1991 under the free and open-source software collaboration. One clone of UNIX is Linux which will be discussed next. It has been designed for multi-user operations (servers are a prime example) and has built-in TCP/IP (Transmission Control Protocol/Internet Protocol) – the fundamental communication protocol used on the internet. It is the most common server operating system on the internet.

Whereas Mac OS X works on Apple Macs and Windows works on Windows PCs, UNIX will work on both, which is why its main usage is on servers. It is a multiuser and multitasking operating system that works independently of the hardware. It was later spelled as UNIX – a sexier spelling in the IT world! This was considered too complex an OS, and was developed into UNICS: Uniplexed Information and Computing System. The original was named MULTICS – Multiplexed Information and Computing System. The term ‘disk operating system’ applied to the disks that were essential for computers to run at that time – either hard disks or floppies, the latter used for business computing with Winchester drives in the early days, and floppies used to load software before PCs with lots of internal memory became commonplace. This was extended by Gates to MS-DOS to be used only by Microsoft. DOS: Disk Operating SystemĭOS was the computer operating system used in the early days of computing and was extended to PC-DOS by Bill Gates when Microsoft was asked by IBM to develop an operating system for the IBM personal computers. Here is some information about the most common OS families in use today. There are many computer operating systems, or OS families, available throughout the world. The various OS systems available are known as “OS Families”.Īll your software or apps run on top of the computer operating system – without an OS your computer would do nothing. Each of these devices needs an ‘Operating System’ or OS to run it and control its overall functioning.

You may have a computer, laptop or a mobile device such as a tablet or smartphone. Computer operating systems are essential for any computer to work.
