Write a note on real time OS.

Ans. In real time operating system , job is to be completed within the rigid time constraints otherwise job loses its meaning. A real time system functions correctly only if it return the correct result within its time constraints

Thus, in a real tome system , the correctness of the computation not only depends upon the logical correctness of the but also upon the time at which the result is produced.

A real time system is often used as a central device in a dedicated applications like fuel-injection system, robotics, air- traffic control, medical imaging systems, systems that control scientific experiment, industrial control system and weapon systems.

Defination of OS(operating system) and its concepts

What do you mean by operating system? Definition : An operating system is a program that act as an interface between the user of a computer and the Computer hardware. Operating system is a first program that gets loaded into the memory through a process called booting. Concepts of operating system : · The purpose of operating system is to provide an environment in which a user can execute program in a convenient and efficient manner. · Operating system is an integrated set of program that ma...

Multi user Operating System

Multi user operating system · In a multi-user operating system, multiple number of user can access different resources of a computer at a same time. · The access is provided using a network that consists of various personal computer attached to a mainframe computer system. diagram of multi -user operating system · The various personal computer can send and receive information to mainframe computer system. · The example of multi-user OS are UNIX, windows 2000,novell netware. sing...

Batch Processing Operating System

Batch processing system · Batch processing is one of the oldest method of running the programs · The computer in the past were very large in size and their I/O devices were very different from those that are used today. The job processing was not interactive as it is today. · The user did not interact directly with computer system. · The process scheduling , memory management, file management and I/Omanagement functions are quite simple in batch processing system 1. Process scheduling (i.e. allocation strategy for a processor is typically in order of their arrival i.e. first come first served(FCFS)basis. 2. Memory management is done by divi...

Scheduler

Scheduler Scheduling Objectives Here, are important objectives of Process scheduling Maximize the number of interactive users within acceptable response times. Achieve a balance between response and utilization. Avoid indefinite postponement and enforce priorities. It also should give reference to the processes holding the key resources Process Scheduling handles the selection of a process for the processor on the basis of a scheduling algorithm and also the removal of a process from the processor. It is an important part of multiprogramming in operating system. Process scheduling involves short-term scheduling, medium-term scheduling and long-term scheduling. Details about these are given as follows − Long-Term Scheduling Long-term scheduling involves selecting the processes from the storage pool in the secondary memory and loading them into the ready queue in the main memory for execution. This is handled by the long-term scheduler or job scheduler. The long-term s...

Exokernel architecture

Exokernel architecture Most of us know what kernels are and how do they work to make programmers’ lives easier. But, how many of us know what exokernels are? I hope you will be able to get a brief introduction on this terminology through this blog. Let’s start with a brief introduction on kernel. What is a kernel? A kernel is the foundational layer of an operating system that functions at a basic level, communicating with hardware and managing resources, such as CPU and the memory. It works as an interface between the user application and the hardware. There are two main types of kernel 1. Micro kernel 2. Monolithic Kernel 1. Monolithic architecture 2. Layerd archtecture . 3. Virtual machine architecture 4. Exokernel architecture 5. Client server architecture 6. Micro kernel architecture Now let’s head into our main focus. What is an Exokern...
