The Operating System (OS) is the most essential software that is loaded first on a computer after you start the system. Operating System is the system software. Communication between a user and the system occurs through operating systems. This blog post on ” what is operating system” aids users in understanding the different kinds of OS and features, functions benefits and drawbacks of OS.
Windows, Linux, and Android are three examples of the operating system that allow users to run programs such as MS Office, Notepad, as well as games on the smartphone or computer. It is required to have at minimum an operating system on the computer to run the basic programs such as browsers.

What is an operating system?
Operating systems are an interface software that connects the device’s user to hardware of the device. It lets users connect to the hardware, and to perform the functions they want to perform.
Operating systems employ two parts to control computer programs and applications. It is called the kernel. The latter is the inner component , which processes data on a hardware level. It is responsible for input-output management processing, memory management and processing management. Shell is an layer that controls the interaction between user and OS. Shell communicates to the OS either receiving input of the user or using a script. The shell script can be described as a series of commands from the system, which are stored in a database.
Types of Operating System
Batch OS
Batch OS is the initial operating system that is designed specifically for second-generation computers. The OS doesn’t directly communicate to the machine. Instead, the operator picks on similar tasks and group them into batches which are carried out one-by-one according to the first-come the first-served principle.
Distributed OS
The concept of distributed OS an incredibly recent technological advancement in technology for computers and is used across the globe that as well at an incredible rate. With a distributed OS several computers are linked by one communication channel. Each computer has its own CPUs and memory units and are referred to as loosely connected systems. The processes of the system can be in different sizes and carry out different tasks. The primary benefit of operating systems is that it allows users to access files that aren’t stored on his system, but are on a different system. Additionally remote access is accessible to all systems that are that are linked to this network.
Multitasking OS
The multitasking OS is called the time-sharing operating system, as each task gets some time to make sure that all tasks are completed efficiently. The system allows access to a wide range of users. Each user is given the same amount of CPU when they are within a single system. The tasks are completed to a single user, or by multiple users. The amount of time allocated to complete the task is referred to as an quantum. As soon as the time needed to finish one task is up then the system shifts to a different task.
Network OS
The Network Operating Systems are software that runs on servers and control all functions of networking. They permit sharing of printers, documents, printers as well as security and networking functions on a tiny network of computers , such as the LAN or different private networks. With the network OS each user are aware of the settings of each other user in the network. That’s the reason why they are often referred to as tightly connected systems.
Real-time OS
Real-time operating systems offer the support needed for real-time systems which need to adhere to strict time constraints. The time it takes between the input and processing and reaction is extremely short which is advantageous for processes that are extremely sensitive and require high precision. These include weapons systems and medical equipment or the air traffic control system which could result in the loss of life or property.
Mobile OS
Mobile operating systems are only available on smaller devices like tablets, smartphones and wearables. It combines the capabilities of a personal computer and other features that are useful on the handheld device. Mobile operating systems are activated when the device is turned on , allowing access to applications installed. Operating systems for mobile devices also control the wireless connectivity of networks.
Wrap Up
The demand for technology increases every day in the future, and as the younger generations such as Gen Alpha grow up & enter the workforce an efficient and effective operating system will become the first priority in every company. If you’re looking to pursue an education in IT then now is the ideal moment to begin.
