A real-time operating system (RTOS) is a computer environment that reacts to input in a specific time period. A real-time deadline may be so small that the system's reaction seems instantaneous. However, the term real-time computing has also been used to describe slow real-time output that has a longer but fixed time-out.
Learning the difference between real-time and standard operating systems is as easy as imagining yourself in a computer game. Each of the actions you take in the game is like a program that runs in that environment. A game that has a real-time operating system for your environment can feel like an extension of your body, since you can count on a specific "latency time": the time between your action request and the remarkable execution of your request by Part of the computer. However, a standard operating system may feel disconnected because the delay time is not reliable. To achieve reliability over time, real-time programs and their operating system environment must prioritize the update of deadlines before anything else. In the game example, this can result in lost frames or lower visual quality when reaction time and visual effects conflict.
Real Time Operating System (RTOS) On hearing this term many computer programmers and enthusiasts think differently. It differs from the rtosgeneral OS purpose, RTOS is a real-time operating system that works with real-time constraints like power, time, and efficient memory usage. Most embedded systems are subject to real-time constraints and are achieved using a real-time system. General-purpose operating systems are suitable for multitasking at the same time, but synchronization is a problem with GPOS. To perform multiple tasks at the worst moment of execution of a particular architecture, a real-time operating system is used in an embedded computer system. The main concern of RTOS is that it produces an accurate output over time or time.
The behavior of an embedded system or a general purpose machine depends on the nature of the application design. A general-purpose operating system was designed to handle multiple tasks without time limit, we can not say that in a certain time a task will be performed.
