What are the Different Types of Operating Systems?
If you work in or want to work in the IT industry, you must be aware of the numerous types of operating systems that are now in use based on the device, manufacturer, and user preferences. A computer’s operating system is used to run various software programmes.
All operating systems strive to control and organise a computer’s resources and processes. Processes, threads, files, gadgets, and networks are a few of these resource managers. Operating systems changed over time as new hardware was created in response to technological evolution.
What is an operating system?
An operating system is a type of system software that enables users to manage hardware and software operations and utilise the resources of a computer. Network operating systems are the pieces of software that let several computers talk to one another and share data and hardware.
The operating system aids in the management of resources like hard drives, RAM, and ROM. Additionally, it enables users to carry out directed tasks like data processing and mathematical calculations. The OS enables users to carry out a number of actions, including data input, processing, and output access. Examples of operating systems include Linux, Mac OS, Windows, and Unix, among others.
Types of operating system
There are the seven different types of operating systems:-
An operating system that uses many processors to boost performance is known as a multiprocessor operating system. On computers with many CPUs, this operating system is frequently present. Systems with many processors perform better because they can run tasks simultaneously on various processors. overall decreases the amount of time needed to execute particular jobs.
Multiprogramming operating systems are those that allow numerous processes to operate simultaneously on a single CPU. Numerous programmes are vying for execution. The ready queue is therefore maintained with these applications. and are gradually assigned to the CPU. When a process is blocked, the CPU is given to other processes in the ready queue. This is done to maximise resource use and increase CPU usage. There are several processes running in RAM in the graphic below (main memory). While process 2 (which was previously running) is now performing I/O operations, other processes are waiting for the CPU.
An operating system that is created to run over a network of computers is known as a distributed operating system. Typically, data and software applications are distributed using distributed systems. Multiple computers’ resources are managed through distributed systems as well. Users may be located at many locations. A single communication channel connects numerous machines. Each computer system has a unique CPU and memory. Disks, computers, CPUs, network interfaces, nodes, and other resources are shared by numerous computers located in various places. It boosts the system’s overall data availability.
Multiple apps can run at once thanks to multi-tasking operating systems. Multiple people can work simultaneously on the same document or application using multitasking operating systems.
Using antivirus software, conducting an internet search, and playing music, for instance. The user is then running a multitasking OS.
An programme that offers a shared user interface with numerous users logged in simultaneously is known as a time-sharing operating system. As long as they are all logged in at once, it enables several users to access the same resources, such as files and apps. The majority of enterprises, particularly those with a large number of concurrent users, employ this type of operating system. Users can do all of their tasks on a system at once thanks to time-sharing operating systems. The most recent development in computer science is the time-sharing operating system, which is gaining acceptance at an ever-increasing rate on a global scale.
Client/server network OS
Client/server network operating systems are used in networks that have both servers and clients as nodes. While clients use these programmes, the servers host the applications or services for users. In a client/server system, in order to securely connect to one another through a network connection, both the server and client computers must have specific software installed.
Each user prepares their work in an independent device, like punchcards in batch operating systems, and delivers it to a computer operator. There are several users. To facilitate computing and enable quicker answers, the various systems divide and distribute similar jobs in batches. A single operator arranges similar work kinds that have comparable needs and criteria into different batches. related job categories with comparable demands and specifications. These operating systems are no longer in use.
We discussed above the different types of operating systems. Every company setting will place the highest premium on having a competent and efficient operating system as demand for technology increases daily in the coming years and as younger generations like Gen Alpha mature and enter the workforce. The greatest time to start if you want to earn a degree in information technology is right now.
