Hi everybody>>wish that i can find the propper answers for my questions.
i have got such a question to answer, and i want to collect as much as possible useful information..... my question is
Explain the following with their areas of application:
a)real time sys.
b)distributed sys.
c)embedded sys.
my answers are like this:
a) Real time systems (RTS): real time is Computing The time duration required by a computer system to complete a particular task, it shows responds to events or signals within a predictable time after their occurrence, the response time must be within the maximum allowed.
real-time computing (RTC) is the study of hardware and software systems. A system is said to be real-time if the total correctness of an operation depends not only upon its logical correctness, but also upon the time in which it is performed.
The software real-time systems are often addressed in the context of real-time operating systems, Example: the software that maintains and updates the flight plans for commercial airliners .Hard real-time systems are used when it is imperative that an event is reacted to within a strict deadline ,Example: a car engine control system is a hard real-time system because a delayed signal may cause engine failure or damage.
Distributed systems: Distributed computing is a method of computer processing in which different parts of a program are run simultaneously on two or more computers that are communicating with each other over a network. It's a type of segmented or parallel computing, Distributed computing is a natural result of using networks to enable computers to communicate efficiently. But distributed computing is distinct from computer networking.
c) Embedded systems: An embedded system is a special-purpose computer system designed to perform one or a few dedicated functions, sometimes with real-time computing constraints. It is usually embedded as part of a complete device including hardware and mechanical parts. In contrast, a general-purpose computer, such as a personal computer, it can do many different tasks depending on programming , Embedded systems span all aspects of modern life and examples of their use the Telecommunications systems . Embedded systems are designed to do some specific task, rather than be a general-purpose computer for multiple tasks.
i would like to recieve your comments according to my answers and would like to get much more from yours.
