The OS, or operating system, which everyone has installed in their computers is something that most of us are acquainted with. Some of the most popular operating systems for laptops and computers are Microsoft’s Windows (XP, Vista, 7,8,10), Apple’s OS X, Chrome OS, and the several Linux versions available from their creators. Real-time Operating Systems, or RTOS for short, is a term that most people are unfamiliar with and this article will define both RTOS and OS for easier understanding.
This article will help you grasp the differences and features of RTOS and OS with a descriptive table and USPs as well.
RTOS vs OS
The main difference between RTOS and OS is that RTOS stands for Real-Time Operating System whereas OS stands for Operating System. RTOS are operating systems that are used for highly specialized projects that involve as near-to-true-time responses as feasible. The most notable distinction between the two is just how they tackle each activity. Whereas, standard operating systems prioritize executing as much processing as possible in the quickest amount of time while RTOS prioritizes predictable response times.
RTOS stands for a real-time operating system which highlights its first feature; to regulate planning, RTOS can deal with interruptions successfully using priority-based functioning. An RTOS, unlike a broad sense OS, is required to fulfill computational deadlines, irrespective of how terrible the circumstance may be. The reliability of an RTOS in regards to the time it takes to receive and execute an application’s job is a critical feature; the variability is referred to as ‘jitter.’
OS, on the other hand, stands for Operating System. The most essential program that executes on a computer is the operating system of the whole computer. Every device with a CPU and GPU is equipped with one operating system or two. The OS controls the storage and operations of the system, as well as all of its firmware including user interface orientations, software, and even hardware feedback. It also facilitates communication with the computer even if you don’t understand its core coded language.
Comparison Table Between RTOS and OS
|Parameters of Comparison||RTOS||OS|
|Full Form||Real Time Operating System||Operating System|
|Definition||As it stands for Real-Time Operating System, this operating system offers quick and precise solutions to prioritized operations.||OS or an operating system is a software application that serves as a conduit between the hardware of a computer and the operator|
|Features||An RTOS can deal with interruptions successfully using priority based functioning||The operating system (OS) on your laptop or pc or even phone controls all of the applications and technology that revolves around your hardware and software|
|Codes||Coding for RTOS is complex and feedback specific.||Coding for a standard OS is generally easy and hassle-free.|
|Performance and Stability||Although real-time operating systems may give greater efficiency in some instances due to reduced concurrency between services and programs, this is not the case in other situations.||Performance is decent and depends partially on the processor and RAM used in the computer.|
What is RTOS?
RTOS is implemented in situations where a high series of activities, many of which are extrinsic to the computing device, must be accepted and taken immediately or under tight deadlines. As it stands for Real-Time Operating System, this operating system offers quick and precise solutions to prioritized operations.
An RTOS must be capable of parallel processing, proactive, and offer thread precedence, to name a few traits. An RTOS must also have a priority inheritance system (PIS), thread synchronization that is predictable, and a method to prevent priority inversion. Airline control systems, Central Command Structures, Defense feedback systems, Peacemakers, security detection mechanisms, and other real-time supervision and executable situations require vast usage of RTOS.
RTOS is utilized in more specialized applications where reaction time seems to be more essential than the capacity to execute a large number of iterations in a brief period. Computers that scan levels and statuses in a building are an example. The sensors must notice changes as soon as they happen. RTOS is a precise and punctual OS that can execute quick operations without taking much time to load.
The changeover procedure is so quick in RTOS that it seems to users as real-time. Some RTOS utilize this architecture as well, albeit with a considerably lower task density to guarantee that the CPU is never overloaded, which might slow reaction times.
What is OS?
OS stands for Operating System, it is an essential part of a computer’s interface. OS or an operating system is a software application that serves as a conduit between the hardware of a computer and the operator. To execute other applications, every system software must have at least one bootloader coupled with an OS. Web browser, MS Exchange, Notepad, executable files, and other applications require a certain environment in order to run and fulfill their functions.
The operating system (OS) on your laptop or pc or even phone controls all of the applications and technology that revolves around your hardware and software. Several computer programs are usually operating at the very same time, and they all obtain access to your computer’s central processing unit (CPU), storage, and disk.
All of this is coordinated by the operating system to ensure that each software receives the resources it requires. Any computer you buy will typically come with an operating system pre-installed. Although the majority of users stick with the default operating system that came with their computers, it is feasible to update or even switch operating systems. Some examples of OS include Microsoft Windows, macOS, and Chrome OS.
Main Differences Between RTOS and OS
- RTOS stands for Real-Time Operating System whereas OS stands for Operating System.
- A real-time operating system (RTOS) specializes in extremely quick reaction times, whereas a traditional operating system (OS) concentrates on sequentially computing throughout the whole array of processes.
- RTOS is user and commands specific whereas an OS is generally used by everyone for daily processes.
- An RTOS uses a sophisticated scheduling algorithm, whereas a regular OS uses a standard approach to solve tasks sequentially.
- Some examples of RTOS include; Vx works, QNX, RTLinux, etc whereas examples of OS include; macOS, Windows, ChromeOS, and android too.
When there are several processes and peripherals, and the scheduling of the processes is more essential than standard results, an RTOS is required. An RTOS is required if numerous processes must run regularly. However, the operating system (OS) is in charge of maintaining a computer’s physical resources and hosting programs that run on it. These duties are performed by an RTOS, which is likewise intended to execute programs with extremely accurate timing and great dependability.
Hence, both RTOS and OS serve various aspects of one command; executing the command prompt given by the operator. However, RTOS prioritizes schedules and timelines whereas a standard OS prioritizes results.
