Basics of Computers Types of OS

Because computers and computing technologies have developed over the years, their use in other areas has grown. More and more customized applications have entered the market to fulfill growing demands. Since every software needs an operating system to function, operating systems have also evolved over the years to meet the increasing demand for their strategies and capabilities. Here we discuss some different categories of operating systems focused on their working strategies and also some popularly used OS.


Graphical User Interface is the acronym for GUI. An operating system that provides an interface composed of graphics and icons is called a GUI OS.

Time Sharing OS

Operating systems that plan operations for the optimal usage of resources are considered time-sharing operating systems. Operating systems utilize time-sharing, or multitasking, while multiple users located at various terminals need processor time to complete their tasks. Some scheduling techniques, such as round-robin scheduling and shortest next scheduling function, are utilized by OS time-sharing.

Real Time OS

An operating system that guarantees that live events or data are handled and the results are transmitted within a given time frame is considered an real-time OS. It may be a single task or multitasking.

Distributed OS

An operating system that handles several computers but provides a single computer interface to the consumer is called a distributed OS. Such kinds of Software is needed when a single computer can not fulfill computational requirements, and more systems need to be used. User interaction is restricted to a single system; it is the OS which distributes work to multiple systems and then introduces the consolidated output as if one computer has been operating on the problem at hand.

Popular Operating Systems

Computers originally had no operating systems. Each program required complete hardware requirements to operate correctly because the programs themselves had to do the cpu , memory, and system management. Nevertheless, operating systems became essential as advanced equipment and more complicated application programs evolved. The business for standard operating system increased as personal computers became common among individuals and small businesses. Let's look at some of the operating systems currently common–
