What are the types of an Operating System?

An operating system (OS) is a software that acts as an interface between the computer hardware and the user, allowing the user to execute programs and manage the resources of the computer. There are several types of operating systems, each designed to meet the specific requirements of different computing environments. In this article, we will discuss six of the most common types of operating systems:

Here are the most common operating systems:

Batch Operating System,
Multitasking/Time-Sharing OS,
Distributed OS,
Real-Time OS,
Network OS, and
Mobile OS.

Batch Operating System

A Batch Operating System is a type of operating system that processes a batch of jobs or tasks in a non-interactive mode. In this type of operating system, the jobs are submitted to the system in a batch and are executed without any interaction with the user. The jobs are processed in a sequential manner, one after the other, without any interruption. This type of operating system was used in the early days of computing when computers had limited memory and processing power. The main advantage of this type of operating system is that it can process a large number of jobs efficiently, making it ideal for large-scale data processing. However, the lack of interaction with the user makes it unsuitable for personal computers or other interactive computing environments.
