Operating System Short Questions Quiz

System software is designed to operate the hardware and provide a platform for running application software. Application software is designed to perform specific tasks or applications for the user.

Software can be categorized into system software and application software. System software includes operating systems, device drivers, and utilities. Application software includes programs like word processors, web browsers, and games.

The kernel is the core component of an operating system that manages resources, handles communication between hardware and software, and provides essential services for other parts of the operating system.

A virtual machine is a software-based emulation of a physical computer that can run its own operating system and applications as if it were a physical machine.

A single-user operating system is designed for use by one user at a time. A multiuser operating system allows multiple users to access the system simultaneously.

In a monolithic structure, all operating system services run in the kernel space. In a microkernel structure, only essential services run in kernel space, with other services running in user space.

CLI allows users to interact with the computer by typing commands. GUI allows users to interact with the computer through graphical elements like windows, icons, and buttons.

A shell script is a script written for a shell to automate tasks. Control statements like if-else and case are used in shell scripting to make decisions and control the flow of the script.

CPU scheduling is the process of determining which processes in the ready queue will be allocated the CPU. Preemptive scheduling allows a process to be interrupted and moved out of the CPU, while non-preemptive scheduling does not allow interruption.

The kernel is the core component of an operating system that manages system resources, handles communication between hardware and software, and facilitates process management.

Preemptive CPU scheduling allows the operating system to interrupt a currently running process in favor of a higher priority process, while Non-Preemptive CPU scheduling does not allow such interruptions.

Waiting time is the total time a process spends waiting in the ready queue before getting CPU time, while turnaround time is the total time taken to execute a particular process from the time of submission to the time of completion.

CPU scheduling is the process of determining which process gets the CPU at what time. Preemptive scheduling allows the operating system to forcibly remove a process from the CPU. Non-preemptive scheduling does not allow the operating system to forcibly remove a process from the CPU.

A shell script is a script written for a shell, or command-line interpreter, of an operating system. Control statements, such as if-else and case statements, are used in shell scripting to control the flow of execution based on certain conditions.

The Kernel is the core component of an operating system that manages system resources. Different types of kernels include monolithic and microkernel structures.

System software manages the computer hardware and provides a platform for running application software. Application software performs specific tasks for users.

The kernel is the core component of an operating system that manages system resources, such as memory, CPU, and devices.

A virtual machine is an emulation of a computer system that runs on a physical machine, allowing multiple operating systems to run simultaneously.

System calls can be classified into process control, file management, device management, information maintenance, and communication.

A time-sharing operating system allows multiple users to interact with a computer system simultaneously by dividing the CPU time among users or tasks.

A single-user operating system allows only one user to interact with the system at a time, while a multi-user operating system supports multiple users accessing the system concurrently.

In a monolithic operating system, the entire operating system is a single executable code that runs in kernel mode, handling all system services.

CLI allows users to interact with the computer through text commands, while GUI provides a visual interface with windows, icons, and menus.

CPU scheduling is a mechanism to allocate CPU resources among multiple processes efficiently, improving system performance and responsiveness.
