An RTOS is not required for an embedded system but it can offer powerful advantages to the system developer. Without an RTOS the developer must write his own code to handle all of these functions. Enables real-time, deterministic scheduling and task prioritization
Abstracts away the complexities of the processor
Provides a solid infrastructure constructed of rules and policies
Simplifies development and improves developer productivity
Integrates and manages resources needed by communications stacks and middleware
Optimizes use of system resources
Improves product reliability, maintainability and quality
Promotes product evolution and scaling
A well-architected RTOS will handle these functions much more efficiently that a programmer could write the code. RTOS developers are expert in how to handle operations with a minimum of processor cycles.

Do machines with built in computers use real time operating systems?
Yes, most machines with built-in computers that perform a sequence of tasks in a precise amount of time require a real-time operating system ( or RTOS ).

What are the characteristics of an embedded computer system?
Most of the popular embedded controllers are for video and sound. An mp3 that plays when a page loads is great if the visitor needs or really wants to hear the automatic sound. A stop or play button can be added as well as how the lloop or file itself plays. A playlist and several more options are available. The video player is still there to automatically play video in the same way, except for the player will become visibale according to the setup. Forward and volume, plus several options are available for the video player. In both of these examples the player will be embedded and the result is the designer has total control over what media the visitor will experience. The major fqctor is what type of system the visitor has will determine whether they hear or see anything at all.
What is a strategy that adopts interface standards that are defined by and widely used throughout industry to facilite the update of components with new technology?
Answer: Open systems Incorrect answers: software-embedded systems automated information systems non-developmental items
What are the tools used for software development while developing embedded systems?
To speed up software development of embedded systems, you can use Data Dictionary Check Tool, Data Monitoring Tool, Calibration Data Tool, Performance Timing Tool, Specification Search Tool, Data Flow Analyzer Tool etc.
What is RTOS?
RTOS stands for Real Time Operating System. Typically these are multi-tasking operating systems used in applications where microcontrollers are used to monitor and control embedded systems (e.g. telecom products). Examples include VxWorks, RTLinux.
What is the difference between the embedded system and RTOS?
An RTOS is an important subset of an embedded system. (See RTOS explanation below) An embedded system has historically been defined as a single function product where the intelligence is embedded in the system. It could be anything from a dishwasher to a hearing aid, if that product includes a microprocessor and software. Many of today's embedded systems are looking more like PCs with user interfaces, touchscreens, displays, keypads and more. Still, these are not general function systems but are designed to perform very specific functions. The processor in these systems are also highly specialized. They are not, generally, the same processor you would find in a PC. A real-time operating system (RTOS) is intended for systems that need to tightly control responsiveness and performance. With an RTOS you can prioritize operations such that the most critical areas of the application get control of the processor exactly when they need it. All other lower priority operations are paused. An RTOS also gives you all of the other advantages of an OS: * a consistent coding platform * a rich set of APIs to save coding time and errors * processor housekeeping functions * hardware abstraction
What Web servers work on a RTOS?
Web (HTTP) servers are not RTOS-dependent. They are part of the application layer of a TCP/IP stack. An embedded web server (such as the Quadnet web server offered by Quadros Systems) is licensed as an option for the underlying networking software.
What are the advantages of embedded systems?
Embedded systems can be run on very limited hardware and do not require a lot of extra "stuff" around. This also makes them excellent candidates as mobile systems.
Do all embedded systems use an RTOS?
no, sometimes no OS is used at all. Instead a hand written scheduling loop is used that calls each function directly. I worked on many such Avionics software systems in the 1980s & 1990s.
What is the difference between soft hard RTOS?
hard real time systems are systems that cant tolerate any delay or if delay happens the whole system will be worthless soft real time systems are systems that can tolerate delay In Vechile we are using Hard RTOS. Soft RTOS using in Live telecasting, Flight updation...
Weather Rtos is necessary and not necessary in embedded system?
The choice to use a realtime operating system (RTOS) in an embedded system is very subjective. Some developers are more likely to use an RTOS than others would be. This might be because they are familiar with a particular system and very comfortable with implementing it. The advantages are that many components are already implemented and tested in an RTOS, such as time slicing, semaphores, and shared memory. Once a developer is familiar with the quirks of a particular operating system, it can save a lot of development time. The disadvantages can be higher runtime overhead, both in memory usage and execution speed (although this is not guaranteed). If a system is extremely complex, an RTOS is likely to be necessary. For simple systems, an RTOS probably makes the source code less readable and therefore less maintainable.
What are the classification of embedded systems?
1.small scale embedded systems 2.medium scale embedded systems 3.sophisticated embedded systems
Advantages and disadvantages of rtos?
RTOS are well... realtime.It means that it is possible to create processes with strict time constraints (like : never more than 5ms delay, the "never" is the important part).The disadvantage is that it will try to meet these time constraints at all costs. Even if it means using less efficient algorithms and completely suspending less critical processes.Because they are often designed for embedded systems, RTOS are usually simpler and smaller than non-RT desktop OSes.
What is best to study Embedded Systems or Mobile technologies?
embedded systems is good....but doing embedded systems is not easy..u should have good programming skills and good background in electronics....u should also have passion to do embedded systems.....
