01. What is an Operating System?
Correct! An Operating System acts as a resource manager, an interface, and a service provider.
02. BIOS is used...
Correct! BIOS (Basic Input Output System) is used by the Operating System during the boot process to initialize hardware.
03. A systematic procedure for moving the CPU to new process is known as
Correct! Context Switching involves saving the state of the current process and loading the state of the new process.
04. What else is a command interpreter called?
Correct! The Shell acts as a command interpreter that takes user commands and converts them into kernel functions.
05. Which among the following is an operating system?
Correct! Linux is a well-known open-source operating system. Java is a language and Oracle is a database.
06. Unix was written in ___ Language.
Correct! Unix was famously rewritten in C by Dennis Ritchie at Bell Labs.
07. An operating system is an interface which provides services to
Correct! It serves users (via GUI/CLI) and programs (via System Calls).
08. LINUX launched its Operating System in the year...
Correct! Linus Torvalds released the first version of the Linux kernel in 1991.
09. Which of the following is NOT a mobile operating system?
Correct! Mojave is a version of macOS for Desktop computers. The others are mobile OSs.
10. To boot a computer means loading computer with
Correct! Booting is the process of powering on the computer and loading the Operating System into main memory.
11. Which of the following services is NOT provided by the operating system?
Correct! People Management is a human resource task, not a computer system task.
12. Linux is a...
Correct! Linux is designed to support multiple users accessing system resources simultaneously.
13. Thread is a...
Correct! Threads are called lightweight processes because they share the same address space and resources of the parent process.
14. Based on the implementation of threads, operating system classifies the threads as:
Correct! Threads are classified into User Level Threads (managed by user libraries) and Kernel Level Threads (managed by the OS).
15. What are major activities of an operating system with respect to resource management?
Correct! While the OS does A, B, and C, option D is the specific definition of Resource Management (allocating CPU time via scheduling).
16. What is considered as the heart of the operating system?
Correct! The Kernel is the core part of the OS that resides in memory and manages all system operations.
17. Any device connected to an operating system is controlled by using:
Correct! Device Drivers are specific programs that act as a translator between the OS and the hardware.
18. In operating systems, which of the following is/are CPU scheduling algorithms?
Correct! All three are standard algorithms used by the scheduler to decide which process gets the CPU next.
19. Process is...
Correct! A process is the active entity of a computer program; it is a program currently being executed.
20. A program in Execution is called...
Correct! As established in the previous question, a program that is currently running is defined as a Process.
