They handle jobs that are serviced by multiple CPUs. Each individual node holds a specific software subset of the global aggregate operating system. https://padlet.com/aizhanabisheva92/xp1siq9s3e9288ie/wish/1995016499

Each user prepares its job on an off-line device like punch cards and submits it to the computer operator. To speed up the processing, jobs with similar needs are batched together and run as a group. The programmers exit their programs with the operator and the operator then sorts the programs with similar requirements into batches.

Therefore, it is really hard for these systems to do multi-tasking.Specific drivers are required for the RTOS so that it can offer fast response time to interrupt signals, which helps to maintain its speed.Plenty of resources are used by RTOS, which makes this system expensive.The tasks which have a low priority need to wait for a long time as the RTOS maintains the accuracy of the program, which are under execution.Minimum switching of tasks is done in Real time operating systems.It uses complex algorithms which is difficult to understand.RTOS uses lot of resources, which sometimes not suitable for the system. https://padlet.com/aizhanabisheva92/xp1siq9s3e9288ie/wish/1995017826 2022-01-17 03:40:26 UTC https://padlet.com/aizhanabisheva92/xp1siq9s3e9288ie/wish/1995017826 Pros and cons https://padlet.com/aizhanabisheva92/xp1siq9s3e9288ie/wish/1995017902
1) Batch Operating System

There is no direct interaction of this operating system with the computer.
There is an individual operator which takes similar kind of jobs having the same needs and requirements and then group them into different batches. It is the work of the operator to sort the jobs with the same requirements.
Advantages:
  • Processors of the batch systems are aware of the time duration of the job even when it is present in the queue.
  • Batch systems can be shared by multiple users.
  • There I very less idle time of the batch system.
  • It enables us to manage the efficiently large load of work.
Disadvantages:
  • It is very difficult to debug the batch systems
  • It proves to be costly sometimes
  • If any job fails, then it is difficult to predict the time
  • There is a lack of interaction between the user and the job
  • It is difficult to provide the desired priority
Examples:
Payrolls Systems, Banks Statement etc.

    1 Sharing of resources.

    2 Reliability.
    more reliable than a central system because if a system has only one instance of some critical component, such as a CPU, disk, or network interface, and that component fails, the system will go down.

    3 Communication.
    A distributed system is a set of computers that communicate and collaborate each other using software and hardware interconnecting components.

    4 Computation speedup
    A distributed operating system manages the system shared resources used by multiple processes, the process scheduling activity, the communication and synchronization between running processes and so on.

In this architecture, all functions and applications are unified under one file server that can be used to execute individual client actions regardless of physical location. Client/server tends to be most expensive to implement and requires a large amount of technical maintenance. An advantage to the client/server model is that the network is controlled centrally, makes changes or additions to technology easier to incorporate.
