Exploring Operating Systems

What are the main types of operating systems?

• Single-User

• Graphical User Interface

• Batch, Time-Sharing, Distributed, Network, Real-Time, Mobile

• Command Line

Define a real-time operating system.

• An RTOS is an operating system that prioritizes user interface design.

• A real-time operating system is designed for single-threaded applications only.

• A real-time operating system (RTOS) is an operating system that guarantees the completion of tasks within specified time constraints.

• An RTOS is an operating system that does not support multitasking.

What is the primary function of an operating system?

• To provide internet connectivity to devices.

• To enhance the graphical user interface of applications.

• To store data permanently on hard drives.

• The primary function of an operating system is to manage computer hardware and software resources.

How does an operating system manage hardware resources?

• An operating system is solely responsible for user interface design.

• An operating system does not interact with hardware at all.

• An operating system manages hardware resources by allocating CPU time, managing memory, controlling I/O devices, and handling storage.

• An operating system only manages software applications.

What is a user interface in the context of operating systems?

• A user interface is a programming language used for system development.

• A user interface is the means for users to interact with an operating system.

• A user interface is the software that manages system resources.

• A user interface is a type of hardware component.

Differentiate between command-line and graphical user interfaces.

• Command-line interfaces are text-based and require typing commands, while graphical user interfaces are visual and use point-and-click interactions.

• Graphical user interfaces require extensive coding knowledge.

• Command-line interfaces are exclusively for mobile devices.

• Command-line interfaces are only used in programming languages.

What is file management in an operating system?

• File management is only concerned with file security and encryption.

• File management refers to the hardware components of a computer.

• File management is the process of handling files in an operating system, including their creation, organization, and access.

• File management is the process of deleting files permanently.

How does an operating system handle file permissions?

• An operating system handles file permissions by defining and enforcing access rights for users and groups.

• An operating system automatically grants all users full access to all files.

• File permissions are only relevant for system administrators.

• An operating system ignores file permissions entirely.

Explain the concept of process management in an OS.

• Process management is the OS function that handles the creation, scheduling, and termination of processes.

• Process management is solely responsible for memory allocation.

• Process management only deals with user interface tasks.

• Process management is the function that manages hardware resources.

What is a process and how is it different from a program?

• A process is a collection of files, while a program is a single executable.

• A process is a static set of instructions, while a program is an executing instance.

• A process is a type of hardware, while a program is software.

• A process is an executing instance of a program, while a program is a static set of instructions.
