Correct Answer - Option 2 : Google Chrome

The correct answer is Google Chrome.

  • An operating system brings powerful benefits to computer software and software development. Without an operating system, every application would need to include its own UI, as well as the comprehensive code needed to handle all low-level functionality of the underlying computer, such as disk storage, network interfaces, and so on.
  • Considering the vast array of underlying hardware available, this would vastly bloat the size of every application and make software development impractical.
  • Instead, many common tasks, such as sending a network packet or displaying text on a standard output device, such as a display, can be offloaded to system software that serves as an intermediary between the applications and the hardware. The system software provides a consistent and repeatable way for applications to interact with the hardware without the applications needing to know any details about the hardware.

  • Operating systems were first developed in the late 1950s to manage tape storage.
  • The General Motors Research Lab implemented the first OS in the early 1950s for their IBM 701.
  • In the mid-1960s, operating systems started to use disks
  • In the late 1960s, the first version of the Unix OS was developed.
  • The first OS built by Microsoft was DOS. It was built in 1981 by purchasing the 86-DOS software from a Seattle company
  • The present-day popular OS Windows first came to existence in 1985 when a GUI was created and paired with MS-DOS.

  • OS Name:
    • Windows
    • Android
    • iOS
    • Mac OS
    • Linux
    • Chrome OS
    • Windows Phone OS
