To perform other programs, every computer must have at least one OS. Applications such as Chrome, Games, MS Word, etc requires an environment where it runs and does its task. The OS allows you to communicate without being able to speak the language of your machine.
Without an operating system , the user cannot use a computer or mobile device. Operating Systems are usually pre-installed in on any computer. Below we will discuss different types of Operating System:. Since Microsoft Windows has been in one form or another and remains the most common home and office software operating system.
The latest versions are also used in some devices, including Windows 10, and the OS is also used on some internet and server computers. Windows may be used by machines from a variety of companies. The start menu of Windows helped generations of users to find their programs and files.
Although the graphical interfaces are different, many of the programming interfaces and command-line features are similar. Signature elements in macOS include the dock used to check for programs and files that are commonly used, single keyboard keys, including the Command key. Linux is a computer operating system which is similar to Unix built under the development and distribution model of free and open-source software. After that, it offers certain tools for other applications that the client wants to run.
Most of the embedded systems run Linux today. Electronic gadgets such as internet router, washing machine, TV, refrigerator, etc can be run on Linux. Hence Linux is also one of the most popular operating systems nowadays. Real-Time operating systems are also called multitasking systems. The RTOS carries out such tasks but is particularly designed with high reliability to run applications at a scheduled or precise time.
The task can be from a single user or different users also. The time that each task gets to execute is called quantum. After this time interval is over OS switches over to the next task. Distributed Operating System — These types of the operating system is a recent advancement in the world of computer technology and are being widely accepted all over the world and, that too, with a great pace.
Various autonomous interconnected computers communicate with each other using a shared communication network. Independent systems possess their own memory unit and CPU. These are referred to as loosely coupled systems or distributed systems.
The major benefit of working with these types of the operating system is that it is always possible that one user can access the files or software which are not actually present on his system but some other system connected within this network i. Advantages of Distributed Operating System: Failure of one will not affect the other network communication, as all systems are independent from each other Electronic mail increases the data exchange speed Since resources are being shared, computation is highly fast and durable Load on host computer reduces These systems are easily scalable as many systems can be easily added to the network Delay in data processing reduces Disadvantages of Distributed Operating System: Failure of the main network will stop the entire communication To establish distributed systems the language which is used are not well defined yet These types of systems are not readily available as they are very expensive.
Network Operating System — These systems run on a server and provide the capability to manage data, users, groups, security, applications, and other networking functions. These types of operating systems allow shared access of files, printers, security, applications, and other networking functions over a small private network.
One more important aspect of Network Operating Systems is that all the users are well aware of the underlying configuration, of all other users within the network, their individual connections, etc. Skip to content.
