What are the types of operating systems?

There are many types of operating systems in use in the present, based on the model, manufacturer, and the preferences of the user It is crucial to understand these types when you work or plan to be working in the area of IT. Operating systems are used to run various software on computers.

Every operating system has one common goal - to manage and arrange the processes and resources of computers. The resource managers are threads, processes devices, files and networks. Operating systems have evolved according to technological advancements and evolved in the years as more advanced hardware created.

What is an operating system?

Operating systems are system software that allows users to regulate the activities of the hardware and software and utilize the computing resources available to them. The operating system for network networks is software that allows multiple computers to share and communicate hardware and files among them. The operating system is used to manage resources like RAM as well as hard disks, ROM as well as other resources. It also permits users to execute specific tasks such as math calculations as well as data processing. The OS allows users to complete different tasks, including input of data, processing operations as well as accessing output. Examples of operating systems include Microsoft Windows, MacOS, Linux, Unix, and many more.

Operating system types

Multiprocessor OS

Multiprocessor operating systems are those that make use of multiple processors to boost performance. It is typically installed on systems that have more than one processor. Multiprocessor systems enhance performance of systems by allowing processing of tasks by multiple processors at the same time. This reduces the amount of time needed to complete certain tasks.

Multi-programming OS

The operating system that can run multiple tasks on one processor is known as the multiprogramming system. There are many programs that need to be executed. These programs are then kept in the waiting queue. They are allotted to CPUs one at a time one. If one of the processes is blocked, then the other processes in the queue ready will be assigned to CPU. This is to ensure the best utilization of resources and higher processing power. In the image below you can see the different processes within RAM(main memory).

Distributed OS

Distributed operating systems are operating programs built to run in conjunction with a computer network. Distributed systems are typically employed to distribute software as well as data. Distributed systems also serve for managing the resource of many computers. Users may be located at various sites.Multiple computers are linked via the same communication channel.Every computer has their own memory and processor. Resources like disk,computer,CPU,network interface, nodes, etc are sharedamong different computer at different locations.

Multitasking OS

Multi-tasking operating systems were designed to allow several applications to run concurrently. Multi-tasking operating systems permit several users to work in the same application or document at the same time.

For instance, a person using an antivirus program, browsing the web, and playing music simultaneously. The user is running an OS that is multitasking.
