Types Of Operating System - Technopedia!!! Types Of Operating System : 1. Batch Operating System 2. Multiprogramming Operating System 3. Time Sharing Operating System 4. Multiprocessor System 5. Clustered Operating System 6. Distributed Operating System 7. Network Operating System 8. Real Time Operating System Types Of Operating System In Detail !!! 1. Batch Operating System Batch system process a collection of jobs,called batch. Batch is a sequence of user jobs. Jobs is a predefined sequence of commands, programs and data that are combined into a single unit. Each job in the batch is independent other jobs in the batch. A User can define a job control specification by constructing a file  with a sequence of commands. Batch monitor is used to implement batch processing system.batch monitor is also called kernel. Kernel resides in one part of the computer main memory. The memory allocator managed the main memory. B...

Difference between a monolithic and micro kernel?  Monolithic kernel Traditional UNIX operating system uses monolithic kernel archilecture. The entire operating system runs as a single program in kernel mode.  Program contains operating system core function and device drivers. Most of the operation performed by kernel is via system call Required system calls are made within programs and a checked copy of the request is passed through a system call. LINUX operating system and FreeBSD uses modern monolithic kernel architecture. It loads the modules at run time.  There is easy access of kemel function as required and minimize the code running in kernel space.  Monolithic Kernel used in Windows 95, Windows 98, Linux and FreeBSD etc.   Advantages :   Simple to design and implement.  Simplicity provides speed on simple hardware.   It can be expanded using module system.   Time tested and design well known...

Services Of Operating System !! Operating System provides different types of services to different users.  It provides services to program like load of data into memory, allocating disk for storage, files or directory for open or read etc. Services will change according to the operating system. May be the two different operating system provides same type of services with different names.  OS makes programmer job easy by providing different services Following are the list of services.  Program execution  Input-output operation  Error detection  File and directory operation  Communication  Graphical User Interface  Recommend Articles For More Information : What Is Operating System?

Operating System As A User Interface And As A Resource Manager !!                       Operating System as a User Interface : Computer system consists of software and hardware to solve specific problems.  User, application program, operating system and the hardware  are the components  of the computer systems. Application program used to solve specific program. Student attendance  monitoring is the example of application program.  Operating  system is a subset of the system software. OS interacts directly with the hardware to provide an interface to other system software. System software and hardware exist to support the creation and effective use application software.

What Is Operating System? Knowledge Of Operating System!!! Operating System :  Operating system is a program that controls the execution of application programs.it is an interface between application and hardware . Os provides different types of view . For users,  it is abstract view because it provides features which are important for users.Os is intermediary between user and the computer system. The major design goals of an operating system are: Efficient use of a computer system. User convenience  ability to evolve An Os is software that manages the computer hardware. The hardware must provide appropriate mechanism to ensure the correct operation of the computer system and to prevent user programs from interfacing with the proper operation of the system. Efficiency is the one of the parameter for use of computer system.Os system consumes some resources during its own operation. Recommend Articles For More Information : What I...
