All About Operating System

Many resources (hardware and software) are available on a computer system and may be required to perform a task. Input/output devices, memory, file storage space, CPU, and other resources are frequently required. The operating system works as a manager of the resources listed above, allocating them to specific applications and users as needed to complete a job.

As a result, the operating system is a resource manager, meaning it can manage a computer system’s resources inside. Processor, memory, files, and I/O devices are the resources. In basic words, an operating system serves as a conduit between the user and the computer. To learn more about operating systems, you can opt for Operating system courses online.

It is critical for you to understand that in order to run other applications, every computer must have an operating system. The operating system is primarily responsible for coordinating the usage of hardware by various system and application applications for diverse users.

An operating system functions similarly to government in that it does not do any valuable functions by itself, but it does offer an environment in which other programs may accomplish beneficial tasks.

  • Computer hardware includes a central processing unit (CPU), memory, and input/output (I/O) devices, and it supplies the system’s fundamental computing resources.
  • Application programs, such as spreadsheets, Web browsers, word processors, and so on, are used to specify how these resources are employed to solve the users’ computing issues. Compilers, loaders, editors, the operating system, and other components make up the System program.
  • The Operating System is primarily responsible for controlling hardware and coordinating its use by numerous applications for diverse users.
  • A computer system is made up of three components: hardware, software, and data.

OS is primarily designed to fulfil two essential functions

  1. The operating system is primarily in charge of allocating and using the computer system’s resources among various users and tasks.
  2. It primarily serves as an interface between the computer hardware and the programmer, simplifying and facilitating coding, application program development, and debugging.

Two Points of View on the Operating System

  1. User’s View: The interface that is being utilized is referred to as the user view of the machine. Such systems are designed to allow a single user to dominate a system’s resources in order to maximize the user’s output. In these situations, the operating system is primarily intended for ease of use, with minor performance considerations but little consideration of resource utilization.
  2. System View: The operating system can also be thought of as a resource manager. A computer system is made up of various resources, such as hardware and software, that must be properly handled. The operating system manages resources, chooses between competing demands, and regulates program execution, among other things.

Management Tasks Performed by an Operating System

  1. Process management, which entails arranging tasks in a logical order and grouping them into digestible chunks before sending them to the CPU.
  2. Memory management, which evaluates the need for virtual memory and coordinates data to and from RAM (random-access memory).
  3. Device management acts as a hub for all linked devices.
  4. Storage management, which guides the long-term storage of data.
  5. A program that lets software and your computer communicate in a standard manner.
  6. You may communicate with your computer through the user interface.

Types of Different Operating Systems

  1. Simple Batch System
  2. Multiprogramming Batch System
  3. Multiprocessor System
  4. Desktop System
  5. Distributed Operating System
  6. Clustered System
  7. Real-time Operating System
  8. Handheld System

Functions of an Operating System

  1. It turns on the computer.
  2. It manages the different peripheral devices, such as the mouse and keyboard, and performs fundamental computer operations.
  3. It has a user interface, for example, a command line or a graphical user interface (GUI)
  4. It manages system resources such as the computer’s memory and the sharing of CPU time by multiple programs or peripheral devices.
  5. It has file management capabilities, which refers to how the operating system manipulates, stores, retrieves, and saves data.
  6. The operating system is in charge of error handling. To avoid mistakes, it takes preventative steps wherever necessary.

Advantages of an Operating System

  • The operating system aids in increasing work efficiency and decreasing complexity, which saves time and effort.
  • Because the many components of a system are independent of one another, the failure of one does not influence the operation of another.
  • The operating system primarily serves as a bridge between hardware and software.
  • Users may use the hardware without having to write huge applications.
  • Sharing data with a big number of users becomes easier with the aid of an operating system.
  • Any game or program may be readily installed and operated on the operating system.
  • An operating system may be readily updated without causing any issues from time to time.
  • An operating system can be readily upgraded.
