Operating Systems


An operating system is a software it acts as an interface between computer hardware and user. It uses some applications such as- MS word, games, chrome, etc need some environment which run and perform different task.The operating system communicate with computer without knowing the computer language and it is not possible for the user to use any computer or mobile devices without having operating system. It used hardware(cpu, memory and hard-drive), operating system(windows, apple OS X and linux)and end user.


Functions of an Operating System are- memory management, processor management, file management, device management, Input/Output management, security, command interpretation, networking, communication management and job accounting.

Types of Operating system- Batch Operating System    Multitasking/Time Sharing Operating system    Multiprocessing Operationg system    Real Time Operating system    Distributed Operating system     Network Operating system    Mobile Operating system


Important subtopics are included in operating system are-

OS - Processes
OS - Process Scheduling
OS - Scheduling algorithms
OS - Multi-threading
OS - Memory Management
OS - Virtual Memory
OS - I/O Hardware
OS - I/O Software
OS - File System
OS - Security


Operating System(OS) is a program which acts as an intermediary between the computer hardware and user and manages and controls execution of all types of programs, at initial stage it is loaded in the computer by a boot program. It provides an environment in which the user executes the program in a convenient and efficient manner. In technical term, operating system is defined as software which manages the hardware and it controls the resource allocation and services like processors, devices, memory and information and it is also known as low-level software that support’s the basic functioning of the computer like recognizing input given from the keyboard, providing output on the display screen, keeping files and directories on a disk, controlling the peripheral devices like drives and printers.


All the other programs on a computer are known as application programs or applications and these applications are processed and executed with the help of OS. Applications use OS by sending request for service with the help of API(Application Program Interface) and users interact directly with OS with user interface like command language or GUI(Graphical User Interface). OS is responsible for security, it ensures that no unauthorized users can access the system.


Operating System is classified as Multiuser i.e., it allows more than two users to run their programs at same time, Multiprocessing i.e., program can run on more than one CPU, Multitasking i.e., more than one program can run concurrently and Real time i.e., responds instantly to the input. Its main services includes: user interface, application program commands, installation supervision, working of programs, hardware, control on input and output functions, allocation of system resource and peripheral devices, managing files and directories and file sharing and network functions.


operating system is the most imperative programming that keeps running on a PC. It deals with the system memory, procedures, and the greater part of its product and equipment. It likewise permits to correspond with the system


Objectives of an Operating System

Simplify the execution of client projects and make taking care of client issues

Use system equipment proficiently

Operating System Views-

Resource allocator

To distribute assets (programming and equipment) of the system framework and oversee them effectively.

Control program

Controls execution of client projects and operation of I/O gadgets.


The project that executes always (everything else is an application )

Time-Sharing Systems-

The CPU is multiplexed among a few tasks that are placed in memory of system and on disk (the CPU is placed to a task)
The task is swapped all through memory to the disk

Parallel Systems -

Multiprocessor frameworks with more than on CPU in close correspondence.
Firmly coupled framework – processors offer memory and a clock; communication happens through the mutual memory.

Distributed Systems -

Distribute the calculation among a few physical processors.

Loosely coupled framework – every processor has its own particular local memory; processors correspond with each other through different networking line.

operating System Structure-

Multiprogramming required for productivity

Single client can't keep CPU and I/O gadgets occupied at all times. Multiprogramming sorts out tasks (code and information)

Timesharing (multitasking) is logical augmentation in which CPU switches jobs so that clients can communicate with every tasks while it is running, in this

time of response < 1 second

Every client has no less than one system executing in memory


What is Operating System ?



An Operating system is software that creates a relation or interface between the User, Software and Hardware. All computers need a basic software known as an Operating System to function. The Operating System acts as an interface between User, Application Programs, Hardware and System Peripherals. The Operating System is first loaded when a computer starts up and then the entire application programs are loaded. Whenever an application needs information or data it requests it from the Operating System which in turn queries the system clock on the motherboard. User interacts with the computer through the Operating System then OS interprets the inputs given by a user through Keyboard, Mouse and other input devices.



An Operating System are of Three Types:


  • Single User Win-ME , MS-Dos, MS-Win 95-98.
  • Multi User XENIX , UNIX, Linux.
  • Network Novel Netware, Win-NT, Win-2000-03
  • Single User: If the single user operating system is loaded in computer’s memory, the computer will be able to handle one user at a time.
  • Multi user: If the multi-user operating system is loaded in computer’s memory, the computer will be able to handle more than one user at a time.
  • Network: If the network operating system is loaded in computer’s memory, the computer will be able to handle more than one computer at a time.

Operating System provides a text based interface referred as command prompt. From the command prompt commands may be issued for performing file and disk management and for running program. Results of these commands are presented to user as text message.

The command prompt may be an alphabet followed by a colon (:), a back slash (\), one greater than sign (>) and a blinking element called as cursor (_).

An operating System is thus intermediary which is formed between both the users and as well as computer hardware. Technically it is the software that manages hardware. Thus an operating System controls

the designation of assets and administrations, for example, memory, processors, devices and data. 

A operating system framework is the program that, is being initially loaded into the PC by a boot program, deals with the various projects in a computer known as application programs. The application

programs make use of operating system so as to work framework demands for administrations through a characterized application program interface (API). 

The most vital elements of operating system are:

Memory Management

Memory administration alludes to administration of Primary Memory or Main Memory. Primary memory is a substantial cluster of words or bytes where every word or byte has its own address. 

Processor Management

In multiprogramming environment, OS chooses which prepare gets the processor when and the amount of time. This capacity is called process scheduling. 

Device Management

Keeps tracks of all the devices. Moreover the program that is responsible for the device management task is known as the I/O controller.

File Management

A file framework is ordinarily composed into indexes for simple navigation and usage.
