Answer / justin
ordinary OS doesnt keep any time constraints n deadlines
whereas RTOS,realtime OS keep time constrains for all
processes that it keeps track of time consumed by each event
n therefore maintains to finish tasks in specified
time..RTOS are designed n installed in systems where o/p
shud obtain in specific time..like mobile phones n all

Answer / satish
The popular RTOS available in the market are
Vxworks,QNX,NetOS,UcosII etc.
The realtime OS provides required service in a bounded
response time.It has the ability to provide the response in
bounded time and it has the above mentioned features.
Realtime systems can be hard realtime and soft realtime
system,it doesn't mean that there is a separate hard RTOS
ans soft RTOS.

Answer / achal ubbott
VxWorks,QNX and some derivatives of LINUX are popular RTOS.
An RTOS is a special case of an OS. Here are few things
which make it different.
1. The scheduler has to be pre-emptive.
2. Each task should have a priority.
3. Priority inheritance should be implemented.

Answer / surbhit
few available RTOS are:
Vxworks,Symbian,RT linux,wiin CE,Brew,android,ucos II
RT systems have to perform under time constraints if the
particular time boundation is not met then it the process
is cancelled and next task starts whereas when an RT os is
operated in a non real time it is a normal OS
