Operating System Book By Charanjeet Singh Pdf



What is an Operating System?




An operating system (OS) is a software program that manages the hardware and software resources of a computer system. It provides a user-friendly interface for interacting with the computer, as well as a platform for running other applications. An operating system also performs various tasks such as memory management, process management, file management, security, networking, and device drivers.


Definition and Functions of an Operating System




An operating system can be defined as a set of programs that control the execution of user programs and act as an intermediary between the user and the hardware. The main functions of an operating system are:


  • To provide a convenient and efficient environment for users to run their programs.



  • To allocate and deallocate the resources of the computer system among the competing processes.



  • To ensure that the computer system operates correctly and efficiently.



  • To protect the data and programs from unauthorized access and malicious attacks.



  • To facilitate communication and coordination among different users and devices.



Types of Operating Systems




There are different types of operating systems based on their design, functionality, and target audience. Some of the common types of operating systems are:


Batch Processing




A batch processing operating system is one that executes a batch of similar jobs or tasks without any user interaction. The jobs are submitted to the system in advance and are processed one after another in a sequential order. The output of each job is stored in an output device or file for later use. Batch processing is suitable for tasks that require minimal user input and high processing power, such as payroll processing, scientific computing, and data analysis.


Multiprogramming




A multiprogramming operating system is one that allows multiple programs or processes to run concurrently on a single processor. The processor switches between the processes based on their priority, availability of resources, and time quantum. Multiprogramming improves the utilization of the processor and reduces the idle time. Multiprogramming is suitable for tasks that require frequent user interaction and moderate processing power, such as word processing, web browsing, and email.


Time-Sharing




A time-sharing operating system is one that allows multiple users to share a single processor or computer system simultaneously. The processor allocates a small amount of time to each user or process in a round-robin fashion. Time-sharing gives the illusion of parallelism and increases the responsiveness of the system. Time-sharing is suitable for tasks that require high user interaction and low processing power, such as online gaming, chat applications, and video conferencing.


Real-Time




A real-time operating system is one that responds to events or inputs within a specified time limit. The system must meet the deadlines and guarantee the correctness and reliability of the output. Real-time operating systems are classified into two types: hard real-time and soft real-time. Hard real-time operating systems have strict deadlines and cannot tolerate any delay or error. Soft real-time operating systems have flexible deadlines and can tolerate some delay or error. Real-time operating systems are suitable for tasks that require high processing power and accuracy, such as industrial control, robotics, and aerospace.


Distributed




A distributed operating system is one that manages a network of computers or devices that work together as a single system. The system is composed of multiple nodes that communicate and cooperate with each other to perform a common task. The nodes can be heterogeneous or homogeneous, centralized or decentralized, and loosely coupled or tightly coupled. Distributed operating systems provide advantages such as scalability, fault tolerance, load balancing, and resource sharing. Distributed operating systems are suitable for tasks that require high availability and performance, such as cloud computing, grid computing, and peer-to-peer computing.


Why Learn Operating Systems?




Operating systems are an essential part of any computer system, and learning them can provide you with many benefits. Some of the reasons why you should learn operating systems are:
