Network Operating System – These systems run on a server and provide the capability to manage data, users, groups, security, applications, and other networking functions. These types of operating systems allow shared access of files, printers, security, applications, and other networking functions over a small private network
Operating Systems - GeeksforGeeks
An Operating System performs all the basic tasks operating systems paper managing files, processes, and memory, operating systems paper. Thus operating systems paper system acts as the manager of all the resources, i. resource manager.
Thus, the operating system becomes an interface between user and machine. Types of Operating Systems: Some widely used operating systems are as follows- Attention reader! All those who say programming isn't for kids, just haven't met the right mentors yet. Join the Demo Class for First Step to Coding Coursespecifically designed for students of class 8 to The students will get to learn more about the world of programming in these free classes which will definitely help them in making a wise career choice in the future.
Batch Operating System — This type of operating system does not interact with the computer directly. There is an operator which takes similar jobs having the same requirement and group them into batches. It is the operating systems paper of the operator to sort jobs with similar needs. Advantages of Batch Operating System: It is very difficult to guess or know the time required for any job to complete. Processors of the batch systems know how long the job would be when it is in queue Multiple users can share the batch systems The idle time for the batch system is very less It is easy to manage large work repeatedly in batch systems Disadvantages of Batch Operating System: The computer operators should be well known with batch systems Batch systems are hard to debug It is sometimes costly The other jobs will have to wait for an unknown time if any job fails Examples of Batch based Operating System: Payroll System, operating systems paper, Bank Statements, etc.
Time-Sharing Operating Systems — Each task is given operating systems paper time to execute so that all the tasks work smoothly. Each user gets the time of CPU as they use a single system. These systems are also known as Multitasking Systems.
The task can be from a single user or different users also. The time that each task gets to execute is called quantum. After this time interval is over OS switches over to the next task.
Advantages of Time-Sharing OS: Each task gets an equal opportunity Fewer chances of duplication of software CPU idle time can be reduced Disadvantages of Time-Sharing OS:. Examples of Time-Sharing OSs are: Multics, Unix, operating systems paper, etc. Distributed Operating System — These types of the operating system is a recent advancement in the world of computer technology and are being widely accepted all over the world and, that too, with a great pace.
Various autonomous interconnected computers communicate with each other using a shared communication network. Independent systems possess their own memory unit and CPU. These are referred to as loosely coupled systems or distributed systems.
The major benefit of working with these types of the operating system is that it is always possible that one user can access the files or software which are not actually present on his system but some other system connected within this network i.
Advantages of Distributed Operating System: Failure of one will not affect the other network communication, as all systems are operating systems paper from each other Electronic mail increases the data exchange speed Since resources are being shared, computation is highly fast and durable Load on host computer reduces These systems are easily scalable as many systems can be easily added to the network Delay in data processing reduces Disadvantages of Distributed Operating System: Failure of the main network will stop the entire communication To establish distributed systems the language which is used are not well defined yet These types of systems are not readily available as they are very expensive.
Not only that the underlying software is highly complex and not understood well yet Examples of Distributed Operating System are- LOCUS, etc.
Network Operating System — These systems run on a server and provide the capability to manage data, users, groups, operating systems paper, security, applications, and other networking functions. These types of operating systems allow shared access of files, printers, security, applications, and other networking functions over a small private network.
One more important aspect of Network Operating Systems is that all the users are well aware of the underlying configuration, of all other users within the network, their individual connections, etc. Advantages of Network Operating System:. Disadvantages of Network Operating System: Servers are costly User has to depend on a central location for most operations Maintenance and updates are required regularly Examples of Network Operating System are: Microsoft Windows ServerMicrosoft Windows ServerUNIX, Linux, Mac OS X, Novell NetWare, operating systems paper, and BSD, etc.
Real-Time Operating System — These types of OSs serve real-time systems. The time interval required to process and respond to inputs is very small. This time interval is operating systems paper response time.
Real-time systems are used when there are time requirements that are very strict like missile systems, air traffic control systems, robots, etc. Two types of Real-Time Operating System which are as follows: Hard Real-Time Systems: These OSs are meant for applications where operating systems paper constraints are very strict and even the shortest possible delay is not acceptable.
These systems are built for saving life like automatic parachutes or airbags which are required to be readily available in case of any accident. Virtual memory is rarely found in these systems. Soft Real-Time Systems: These OSs are for applications where for time-constraint is less strict. Advantages of RTOS: Maximum Consumption: Maximum utilization of devices and system, thus more output from all the resources Task Shifting: The time assigned for shifting tasks in these systems are very less.
For example, in older systems, it takes about 10 microseconds in shifting one task to another, and in the latest systems, operating systems paper, it takes 3 microseconds.
Focus on Application: Focus on running applications and less importance to applications which are in the queue. Real-time operating system in the embedded system: Since the size of programs are small, RTOS can also be used in embedded systems like in transport and others. Error Free: These types of systems are error-free. Memory Allocation: Memory allocation is best managed in these types of systems, operating systems paper.
Disadvantages of RTOS: Limited Tasks: Very few tasks run at the same time and their concentration is very less on few applications to avoid errors.
Use heavy system resources: Sometimes the system resources are not so good and they are expensive as well, operating systems paper. Complex Algorithms: The algorithms are very complex and difficult for the designer to write on. Device driver and interrupt signals: It needs specific device drivers and interrupts signals to respond earliest to interrupts. Thread Priority: It is not good to set thread priority as these systems are very less prone to switching tasks, operating systems paper.
Examples of Real-Time Operating Systems are: Scientific experiments, medical imaging systems, industrial control systems, weapon systems, robots, air traffic control systems, etc. Skip to content.
