Networks OS

NETWORK OS

Most of the network os works under the principle of client-server mechanism. Client –server is a mechanism. In which co-operation and intercommunation between various elements of network takes place and one machine service others for various functions.

                 In a network OS , the users are aware of the existence of multiple computers and can the functionally of the remote server machines. In other words, a user doesn’t have to sit in front of machine in which he wants to work on the job of the system software is to manage the operation  of computer as a whole .Where as the application program server the purpose of general useormfor application software of computer system .In other words, system software provides the peat

Real Time Operating system

Real-time operating systems are dedicated to some well-defined jobs which require very fast response time .The system must be fault –tolerant that is os must handle the error without going to unstable stage. The execution time is the most critical issue in real time so and they must  finish the execution of the job within pre-defined time; boundary. The example of programs that run in real –time Os are: missile guiding system, medical monitoring system, flight simulation system etc. To finish the job after the dead line is as worse as not performing the job.

Online processing operating system is almost similar to real operating system but the result must be obtained in the presence of the user .The system for querying the bank balance in the account can be best example of online processing where result is obtained directly from the main database in the presence of the customer demanding information.

Operating system

 The operating system is defined as set of programs that controls the entire operation of the computer such as handling input\output operation, user request interrupts etc. The operating system manages the resources of a computer system and schedules its operation.It is a master supervisor program which provids a frindly interface for the user to intract with the computer and its preipherals and different application software as well as an enviroment execute.   for program to execute.                                                                                                     

                      

                         Operating system is a computer program that acts as an intermediate between the user and computer hadware. This is the first software we see when we turn on the computer and again the last softwarewe can seewhen the computre is turn off.As computer consists of various resource like memory,cpu,disks etc.,it's very difficult for the user of the computer to understand how to operate them directly. So, os becoms the interpreter between the computer hadware and user.It interprets the command of the user to the hardware and present the output to user in a sutaible format proudce by hardware.
