The Real Concept Of Operating System - Its Operations




 Concept Of Operating System
 Concept Of Operating System

 Operating system is nothing but it is a program it is a program that acts as an intermediary between user of a computer user of a computer and computer hardware so it's just acting act as an interface between the user and the computer hardware so in your car in your computer you are having the hardware parts. So if you want to work those Hardware parts you want you need to install some software to run that hardware part so it's access and this operating system acts as an interface between the user of the computer and the computer hardware are :


  • Computers
  • Printers
  • CPU
  • Mouse
  • Cables



The Real Concept Of Operating System 


So that exactly the operating system is so you have to call that operating system is nothing but it is a software it is a program it is a program that acts as an intermediary between the user and the computer hand okay or else it is a program you can call this operating system is a program that controls that controls the execution of application program. That controls the execution of application program so you can call like this also so it is a program there that operating system is nothing but it is a program that controls the execution of the application program. So in brain we can say that this operating system acts as an interface between application and hardware so in general you can call this operating system as an interface between the application and hardware.


 Now coming to what is the main objective of using this operating system why we are using the operating system the main objectives of an operating system the main objective is for convenience and for efficiency the system efficiency and for ability to evolve means the ability to solve the problems so this is the main objective of using the operating system ok. So here in this video I am just explain the basic concept of the operating system now coming to the different services that operating system can provide operating system services so what are the services that it can provide program development it can provide program development and program execution this operating system can provide the service of program execution it help to access the i/o devices access our devices and control access to file system.


 So file system access error detection and response so these are the different services that operating system can provide so it helped in program development it helped in program execution and to access the different type of devices and it access to file system and if there is any error detection and error the quick response everything will be provided by these operating systems so you have to think that operating system is nothing but it is a software which enables the hardware so whatever the hardware components that are present in a computer. So if you take the computer or a mobile out whatever the gadget here had taken so in that you are having the hardware Hardware components to activate these hardware components to activate means to work these hardware components we need operating system to activate the hardware components we need operating system that is nothing but add as a software so this operating system is of a different types means you can install the Windows Linux UNIX ok.


 Operations Of Operating System


 Different operating systems are present now coming to this role what is the role of operating system role of operating system a computer a computer is a set of resources we all know that a computer consisting of set of resources so what set of resources its having these resources were used for moment means copying the data storage and processing data a computer is a set of resources for movement storage and processing data .So here the operating system is responsible is main responsible for managing these resources managing these resources. So operating system is the main responsible for managing the movement storage and processing data that is inside the computer ok now let us see the computer system actually what are the system components computer system components so what are the components that are present in the computer let us see that so the different components that are present in the system are we know that the hardware so what are the hardware parts the hardware's are nothing .


CPU MANAGEMENT TECHNIQUE


But the CPU the central processing unit means the processor memory input/output devices everything related to hardware so the computer consisting of suffice the hardware and next it consisting of operating system so operating system is a software which is used to run this hardware and you need some application programs application programs ok and the another component that is present in computer is the users so the users may be anything means like the people means we are the users ok so the user may be the people or you can take a machine machine or other computers also you call it as a users so.


 Whenever you are seen the users you don't estimate that the user is nothing but it is only the people no it is not the people ok the user may be machine or it may be the other computer ok so here the interaction between the user and the hardware okay so this completely it's a computer or else the user maybe one computer is interacting with the another computer one computer is interacting with the another computer so here this you call it as a user this user is interacting with the another computer so like that so everything the computer system components or the hardware it consists of Hardware operating system application programs and the users .So let me write that so here if you take I'm just writing the abstract view of the system abstract view of system so let us see what is the abstract view of the system so here.


 I'm just taking suppose I uses this is one user use it so user one I said user may be a people or a system or any other computer ok user 1 user 2 use a 3 up to user and ok so many users can interact so these users are interacting with the user is in first one user is interacting with the compiler assembler or text editor means any of the application program here you call this as an application programs.


 The compiler,  assembler ,text editor these are all application programs or else the database system database system so this is the system and application program application program.

 So here you are having operating system operating system so this operating system consisting of this is the computer hardware so this is completely the abstract view of a nice whatever the system you have taken the computer system okay that computer system abstract first you are having the computer hardware this computer hardware is communicating in between the application program and the computer hardware and operating system  parts are :


  • UNIX
  • Hardwares
  • Softwares


Is there so this operating system is acts as an interface between the application program and the computer hardware so the application program may be any of the programs that is a compiler assembler text editor database system everything that is present in the to run the programs okay so to run the programs we need some applications so those applications are already installed in this system so means in the operating system .So here the different uses the user 1 ,user 2 ,use a 3 ,up 2 user and these users may be the people or a or a system or any other computer component computer ok so this is just an abstract view of the system now let us see the different evaluations of operating system evaluation soft operating system .

Evaluations Of Hardwares


So what are the different evaluations of operating system a major operating system will evolve over time for a number of reasons .So each time the operating system maybe is upgrading for number of reasons so what are those reasons so that those reasons may be a hardware upgrade means it may be any hardware upgrade or it may be new a new type of hardware is added a new type of hardware is added or a new services are provided new services are provided so for those reasons every time the operating system is going to be evolved .So whenever the hardware is upgraded or new had type of hardware is added or there's some new services or introduced so we have to evolve this operating system so the stages that are included in this operating system is stages included in this operating system is suppose if you have taken anything like so here the stages are first it takes the serial processing the starting stage of operating system is always in the serial processing next it use the simple batch system next stage of operating system they go for the simple bag system next it is going for the multi programming batch of system multi programmed batch system and time sharing system time sharing system so still some more stages or that means a parallel system distributed system real operating system so this is the different stages that are included in the evolution of operating system for so first it starts with the serial processing and it .



Continuing still it is continuing the evaluation of the operating system is still continuing okay so this is about the different stages that are included in the operating system so this video covers the J the introduction part of the operating system .
