Operating Systems: Question and Answer Guide
Introduction to Operating Systems
Q1: What is an Operating System (OS)?
A: An OS is system software that manages hardware resources and provides
services for computer programs. It acts as an interface between the user and the
hardware.
Q2: What are the primary functions of an OS?
A: The primary functions include:
1. Resource Management
2. Process Management
3. File System Management
4. Security and Access Control
5. Error Detection and Handling
Q3: Can you name some popular operating systems?
A: Windows, Linux, macOS, Android, iOS, and UNIX.
Types of Operating Systems
Q4: What is a Batch Operating System?
A: A Batch OS processes jobs in batches without user interaction. Jobs are
grouped by type and executed sequentially.
, Q5: What is a Time-Sharing Operating System?
A: A Time-Sharing OS allows multiple users to use the system simultaneously by
allocating small time slices to each task.
Q6: Define a Distributed Operating System.
A: A Distributed OS manages a network of independent computers and makes
them appear as a single system to users.
Q7: What is a Real-Time Operating System (RTOS)?
A: An RTOS is designed to process tasks within strict time constraints, ensuring
predictability and reliability. Examples include VxWorks and FreeRTOS.
Q8: What is the primary focus of Mobile Operating Systems?
A: They are designed for smartphones and tablets, focusing on power efficiency,
user interface, and app ecosystems. Examples include Android and iOS.
Q9: Explain an Embedded Operating System.
A: Embedded OSs are tailored for specific devices like microwaves or automotive
systems, offering high efficiency and reliability.
