Computer Operating Systems: OS Families for Computers

The Examples Of Operating Systems Computer Science Essay. Apr 16,  · There are several types of operating systems on the market. The main operating systems for computers are Microsoft Windows, macOS, and Linux. Besides, other operating systems are also utilized. What is the best OS for computers?

This is a list of operating systems. Computer operating systems can be categorized by technology, ownership, licensing, working state, usage, and operatiing many other characteristics. In practice, many of these groupings may overlap.

Feb 18,  · An operating system (OS) provides the user with a way to access the computer's hardware. Microsoft Windows® is a series of operating systems that is installed on the majority of personal computers (PCs). Mac OS® is another popular type of operating system. Linux operating systems are free alternatives to Windows® and Mac OS®.

TechLila Computer. Computer operating systems are essential for any computer to work. You may have a computer, laptop or a mobile device such as a tablet or smartphone. All your software or apps run on top of the computer operating system — without an OS your computer would do nothing. There are many computer operating systems, or OS families, available throughout the world.

Here is some information about the most common OS families in use today. It is still available today. Microsoft Windows is likely the most well-known and common computer operating system in the world today. Users can run a multitude of programs or applications apps , each in its own window, with icons representing clickable links to specific applications. Many PCs are sold with Windows already installed. Mac OS was developed to run the Apple Macintosh computer system.

Apple computers were introduced in , and Mac OS was the first commercially successful computer to use a GUI and was likely what prompted Microsoft to develop Windows. Version 7. This is just one example of how operating systems can develop and be hybridized with the acquisition of totally different operating systems! The above three computer operating systems are the major operating systems that have been used over the years for personal computers — PCs and laptops.

It is a multiuser and multitasking operating system that works independently of the hardware. It is the most common server operating system on the internet. As stated above, Linux was derived from UNIX — derived by Swede Linus Torvalds and released to the public in under the free and open-source software collaboration. 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.

It is used on all types of computer, including laptops, mainframes and also mobile devices in one form or another. Android , for example, has been written specifically on top of the Linux kernel. It is a very stable operating system, but will only run software written particularly for Linux. It is a general purpose operating system with more installations than any other.

Once developed, however, it became purely the domain of IBM who marketed and managed it. It was renamed Oracle Solaris, and supports multiprocessing and multithreading operations. Solaris Nevertheless, for anybody focussing on the cloud, Solaris could be a good choice of OS on which to write cloud-based software. Designed for microcomputers and workstations, the VMS virtual memory system is a multi-tasking OS for multiple users that was launched in along with the VAX Minicomputer.

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

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. Even though it is 30 years old, clients who use it believe that it will last for eternity. It exploits the virtual memory concept, and was used on the VAX computer — now no longer made, but with some models still in use.

Developed in , this OS is still being used, but gradually being replaced with a more modern operating system. Real time computer operating systems are used when a rapid response to data input is required.

With RTOS, response to data input will sufficiently fast to affect data added shortly afterwards. Embedded microprocessors often employ an RTOS system. A critical factor in the effectiveness of an RTOS is known as jitter. Hard and Soft real-time operating systems have differing jitter, the former being the lower.

When designing a real time operating system, the jitter is more important than overall throughput. If a real time operating system can usually meet a deadline it is known as a soft real-time OS, but if it can meet it as an inevitable consequence then it known as a hard real-time OS. An RTOS is very important where rapid response to data input is essential. Examples of these: An RTOS for air bag deployment must be hard real-time, because a delay in deployment could be catastrophic.

On the other hand, and RTOS for video streaming to a computer can be soft, because the occasional loss of data is not catastrophic. Apple Macs could not compete in this market with the high-end design features of higher class computers and it was not competitive. However, it did have some corporate success and also in sales to the U. S, Government. MAE was introduced by Apple in MSE 3. These are the major computer operating systems OS Systems used to date. There may be others — in fact there are others — that have played a minor part in the development of modern computing.

There also computer operating systems used specifically for mobile units and smartphones. Among these are the iOS, Android and the Windows mobile system. Here, however, we are focusing on computers — mainframes, desktops and laptops. Mobile systems may one day become the subject of a separate report. Thanks for sharing. Really nice overview. Perfect for anyone trying to get a good understanding of the various operating systems currently available.
