What is the difference between rtos and OS what are the advantages and disadvantages of rtos?
an RTOS is much better than anormal OS because it is time sensitive, fault tolerable and allow multiprocessing. that are not supported by all OSsA real-time operating system 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 platforma rich set of APIs to save coding time and errorsprocessor housekeeping functionshardware abstraction
What are the features of RTOS?
- A RTOS(Real-Time Operating System) has to be multi-tasking and pre-emptible - task priority has to exist - Behaviour of OS should be known - A System of priority inheritance has to exist. - Following parameter should be clearly specified The Interrupt Latency(i.e. time from interrupt arrival to start of execution of ISR) , this has be compatible with application requirements and has to be predictable. RTOS is a real time operating system.The important features are :- - The necessary signalling functions between interrupt routines and taskcodes are handled by RTOS. - It works as an independent system with no internal or external interdependencies. - There are no loop descisions in RTOS - The RTOS can suspend one task code subroutine in the middle order to run another - The time lag is veryless compared to other systems - There are no random time variables, this is good for a direct relationship between instruction and process. - Tasks are simpler to write. - Under most RTOS tasks are simply subroutines.
What are the differences between various operating systems?
difference between layered and kernel base approach in OS structure
What are five well known operating system?
Apple OS X Microsoft Windows Unix Linux VAX/VMS OS4000 IBM System/360 DOS IBM OS/2 RISK OS Free RTOS OS 2200 Exec 8 (There are lots more)
Can you use a RT OS as normal OS?
No a RTOS is used only for real time applications and does not have many needed feature of a normal OS.
What are the differences between Unix and Mac OS X?
Unix is a specification. Mac OS X is a certified implementation of Unix. This like asking "What is the difference between a turtle and a red-eared slider."
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 are two differences between the original Mac OS and windows?
There are several differences between the original Mac OS and windows. Two of these differences include the fact that Widows was susceptible to viruses while Mac was not, and the MAC did not have menus in their windows. You could close a window and have the application still run. Windows had menus on each window and when the window was closed, the application stopped.
What is general OS?
OS stands for Operating System.
What are the differences between DOS and Windows OS?
Dos is single user single task and windows single user multi task
Conclusion of real time operating system?
real time os is most imp bcz there is lot of need for the applicaion on os bt bcz of time & correctness the o/p is not so goo. using rtos we cn create the crrct output for ahe application
