FREE Bachelor of Computer Engineering Operating System Questions and Answers

Question 1

What exactly is an operating system?

Accepted Answer

All of the above

Answer

An operating system (OS) serves multiple crucial roles in a computer system. It acts as an interface between the hardware and application programs, allowing software to interact with hardware resources. Additionally, it manages these hardware resources efficiently and provides essential system services to application programs. Therefore, all the listed statements accurately describe what an operating system is.

Question 2

What is the command interpreter's primary purpose?

Accepted Answer

to get and execute the next user-specified command

Answer

The command interpreter, often called a shell, is a crucial component of an operating system. Its primary purpose is to read and parse commands entered by the user. Once a command is interpreted, the command interpreter is responsible for executing that command, typically by invoking the appropriate system calls or programs.

Question 3

The interface is given by the operating system and allows users to access its functions.

Accepted Answer

System calls

Answer

System calls provide the programmatic interface through which user-level applications request services from the operating system kernel. They are the fundamental mechanism for interacting with the OS, allowing programs to perform privileged operations like file I/O, process creation, and memory management. APIs often build upon these system calls to offer higher-level functionality.

Question 4

Which of the following statements is untrue?

Accepted Answer

kernel is made of various modules which can not be loaded in running operating system

Answer

Modern operating system kernels, especially monolithic kernels with modules or hybrid kernels, are designed to be modular. This means that various kernel components, such as device drivers or file systems, can be loaded into and unloaded from the kernel while the system is running. This dynamic loading capability enhances flexibility, reduces memory footprint, and allows for easier updates and extensions without requiring a full system reboot.

Question 5

Which of the following errors will the operating system deal with?

Accepted Answer

All of the above

Answer

An operating system is responsible for handling a wide range of errors to maintain system stability and provide a robust computing environment. This includes managing hardware-related issues like power failures and printer problems, as well as network connection failures. By detecting and responding to these errors, the OS ensures that the system can recover or inform the user appropriately.
