The features of operating systems are increasing day by day. Because at the starting development of the OS it was used to handle storage taps but now it is working on GUI by throwing brilliant colours.Given below are the features of the operating system −Memory ManagementThe operating system controls the primary memory or main memory.Primary memory is a large array of bytes or words where each byte or word is assigned a certain address.It is a fast storage, and it can be accessed directly by the CPU which is present inside the system. If a program wants to be executed, ... Read More

Kernel is the important part of an Operating System. The kernel is the first program that is loaded after the boot loader whenever we start a system. The Kernel is present in the memory until the Operating System is shut-down.Kernel provides an interface between the user and the hardware components of the system. When a process makes a request to the Kernel, then it is called System Call.FunctionsThe functions of the kernel are as follows −Process managementAccess computer resourcesDevice managementMemory managementInterrupt handlingI/O communicationFile system...etc.Access Computer resource − A Kernel accesses various computer resources like the CPU, I/O devices and other ...

Each operating system has its own advantages and disadvantages, let us discuss in general the benefits and drawbacks of operating systems.AdvantagesThe advantages of Operating system are as follows −Computing Source − OS acts as an interface between the user and the hardware. It allows users to perform different tasks like input data, process the operation, and access the output. With the help of an operating system, users can communicate with computers to perform various functions like arithmetic calculations.User-Friendly Interface − Whenever the Windows operating system came into existence with Graphical User Interface (GUI), it became user friendly. It also helps ... Read More

The operating system is a software which handles the computer's functionality like scheduling, input/output operation, resource allocation, file system manipulation, etc. and it acts as an interface between the user and hardware.The different types of operating systems are as follows −Batch Operating SystemMultiprogramming Operating SystemMultitasking Operating SystemMultiprocessing Operating SystemReal time Operating SystemLet us discuss the embedded operating system.Embedded Operating systemAll Embedded Systems are task specific. They mostly do a particular task on loop/repeatedly for their entire lifetime. These systems are designed to execute their task within a particular time interval, and thus they have to be fast enough to be ... Read More

The operating system is a software which handles the computer's functionality like scheduling, input/output operation, resource allocation, file system manipulation, etc. and it acts as an interface between the user and hardware.The different types of operating systems are as follows −Batch Operating SystemMultiprogramming Operating SystemMultitasking Operating SystemMultiprocessing Operating SystemReal time Operating SystemNow let us discuss the Network operating system.Network Operating SystemThe OS specializes in network devices such as a router, switch, or firewall. The OS manages these network resources. The OS supports workstations, Personal Computers (PCs), older terminals connected on a Local Area Network (LAN).Examples of Network OSs are Microsoft ...

Distributed Operating System is a type of model where applications are running on multiple computers linked by communications. It is an extension of the network operating system which supports higher levels of communication and integration of the machines on the network. Distributed OS runs on multiple CPUs but for an end-user, it is just an ordinary centralized operating system. It can share all resources like CPU, disk, network interface, nodes, computers, etc. from one site to another site, and it increases the data available on the entire ... Read More

The operating system is a software which handles the computer's functionality like scheduling, input/output operation, resource allocation, file system manipulation, etc. and it acts as an interface between the user and hardware.The different types of operating systems are as follows −Batch Operating SystemMultiprogramming Operating SystemMultitasking Operating SystemMultiprocessing Operating SystemReal time Operating SystemNow, let us discuss the Real time operating system.Real-time operating systemAll real time operating systems are designed to execute their task within a particular time interval, and thus they have to be fast enough to be up to their deadline.Time constraints related with real-time systems simply means that time ...

The different types of operating systems are as follows −Batch Operating SystemMultiprogramming Operating SystemMultitasking Operating SystemMultiprocessing Operating SystemReal time Operating SystemNow, let us discuss the Time sharing operating systemTime sharing Operating systemLogically, it is an extension of multiprogramming as in multi programming the user cannot interact properly with the system but in time-sharing it is possible because in this CPU executes multiple processes by switching among them and giving the CPU time to each process and in this time the user can also interact with the process.Time-sharing OS provides short response time as the user can also directly give instruction ...

To avoid the drawbacks of early systems the batch processing systems were introduced. The early systems required more setup time.To overcome this drawback, batch processing is used where the more set up time was reduced by processing the jobs in batches in this approach similar jobs were sent to the CPU for processing and were run together.The important task of the batch processing system is to automatically keep executing the job in batches to reduce the setup time.In the early job processing systems, the jobs were placed in a job queue and the memory allocated or managed by the primary ...
