    • Compiler

    • Loader

    • Operating system

    • Assembler

    Correct Answer
    A. Operating system
    Explanation
    The operating system is responsible for managing all the hardware and software resources of a computer. It controls the boot process, which is the initial startup of the computer, and ensures that all necessary components and drivers are loaded into memory. Without an operating system, the computer would not be able to initiate the boot process and therefore cannot start up. The compiler, loader, and assembler are all software tools that are used during the development of programs, but they are not essential for the computer to boot up.

    • Disk Operation System

    • Dynamic Operating System

    • Disk Operating System

    • Dynamic Overload System

    Correct Answer
    A. Disk Operating System
    Explanation
    The correct answer is "Disk Operating System". DOS stands for Disk Operating System, which is a computer operating system that was widely used in the 1980s and early 1990s. It was primarily designed to manage and control the operations of a computer's disk storage, including reading and writing data to and from disks. DOS was commonly used on personal computers and was known for its command-line interface, where users had to type commands to perform various tasks.

    Which of the following are loaded into main memory when the computer is booted?

    • Internal command instructions

    • External command instructions

    • Utility programs

    • Word processing instructions

    Correct Answer
    A. Internal command instructions
    Explanation
    During the boot process, the computer loads the internal command instructions into main memory. These instructions are essential for the computer to perform basic operations and functions. They are typically stored in the computer's firmware or BIOS. Loading these instructions into main memory allows the computer to execute commands and perform tasks as soon as it is booted up.

    • Both

    • None

    Correct Answer
    A. CUI (Character User Interface)
    Explanation
    The correct answer is CUI (Character User Interface) because DOS (Disk Operating System) was primarily a command-line operating system that relied on text-based commands rather than graphical elements. It did not have a graphical user interface like modern operating systems, such as Windows or macOS. Instead, users interacted with DOS by typing commands and receiving text-based responses.
