Introduction to Computer Software

An operating system (OS) is system software that manages computer hardware, software resources, and provides common services for computer programs. ... The dominant desktop operating system is Microsoft Windows with a market share of around 82.74%.

Types of Operating Systems

  • Batch Operating System – This type of operating system does not interact with the computer directly. ...

  • Time-Sharing Operating Systems – Each task is given some time to execute, so that all the tasks work smoothly. ...

  • Distributed Operating System – ...

  • Network Operating System – ...

  • Real-Time Operating System

A real-time operating system (RTOS) is an operating system (OS) intended to serve real-time applications that process data as it comes in, typically without buffer delays. ... A real-time system is a time-bound system which has well-defined, fixed time constraints.

Comparison of real-time

What is real time operating system and its types?

Important components of RTOS system are: 1)The Scheduler, 2) Symmetric Multiprocessing, 3) Function Library, 4) Memory Management, 5) Fast dispatch latency, and 6) User-defined data objects and classes. Three types of RTOS are 1) Hard time 2) Soft time ,and 3) Firm time

Pseudo real-time operating system

Such operating systems are best described as quasi-realtime or pseudo-realtime in that they execute realtime activities in preference to others whenever necessary, but don't adequately account for non-schedulable activities in the system.
