What is an operating system and why is it important?




An operating system (OS) is a software program that manages the hardware and software resources of a computer system. It provides a common interface between the user and the machine, allowing the user to run applications, access files, control devices, communicate with other computers, and perform other tasks. An operating system also performs essential functions such as memory management, process scheduling, disk management, security, error handling, and more.


An operating system is important because it makes the computer system usable and efficient. Without an operating system, a user would have to interact with the hardware directly, which would be very difficult and time-consuming. An operating system also enables multiple users and programs to share the same computer system without interfering with each other. An operating system also enhances the performance and reliability of the computer system by optimizing the use of resources and handling errors gracefully.


The basic functions of an operating system




An operating system performs four basic functions:


  • Resource abstraction: An operating system hides the details and complexity of the hardware from the user and provides a simple and uniform view of the resources. For example, an operating system abstracts a disk drive as a logical unit that can store files and directories.



  • Resource sharing: An operating system allows multiple users and programs to access the same resources concurrently without conflicts or inconsistencies. For example, an operating system ensures that two processes do not write to the same file at the same time.



  • Resource allocation: An operating system decides how to allocate the available resources among competing users and programs according to some criteria such as fairness, efficiency, or priority. For example, an operating system determines which process gets to use the CPU next.



  • Resource protection: An operating system protects the resources from unauthorized or improper use by enforcing security policies and mechanisms. For example, an operating system requires a user to enter a password before accessing a file.



The types of operating systems and their features




There are many types of operating systems that differ in their design goals, target platforms, functionality, and user interface. Some of the common types of operating systems are:


  • Batch systems: These are the earliest type of operating systems that execute a sequence of commands or jobs in a batch mode, without user interaction. Batch systems are suitable for tasks that are repetitive, predictable, and require minimal input and output. For example, payroll processing, data analysis, and printing.



  • Timesharing systems: These are the type of operating systems that allow multiple users to use the same computer system interactively, by switching the CPU among them in a rapid manner. Timesharing systems are suitable for tasks that are interactive, unpredictable, and require frequent input and output. For example, email, web browsing, and online gaming.



  • Personal computer systems: These are the type of operating systems that run on single-user personal computers or workstations, such as desktops, laptops, or tablets. Personal computer systems are suitable for tasks that are personal, diverse, and require graphical user interface. For example, word processing, spreadsheet, and multimedia.



  • Distributed systems: These are the type of operating systems that run on multiple computers that are connected by a network, such as the Internet. Distributed systems are suitable for tasks that are collaborative, scalable, and require high performance. For example, search engines, social networks, and cloud computing.



  • Real-time systems: These are the type of operating systems that run on computers that control physical devices or processes that have strict timing constraints. Real-time systems are suitable for tasks that are critical, deterministic, and require fast response. For example, air traffic control, industrial automation, and robotics.



  • Embedded systems: These are the type of operating systems that run on computers that are embedded in other devices or appliances that have specific functions. Embedded systems are suitable for tasks that are specialized, constrained, and require low power consumption. For example, smartphones, smart watches, and smart cars.
