Course Introduction
Introduction to Operating Systems provides an in-depth exploration of the fundamental concepts and structures underlying modern operating systems. The course covers essential topics such as process management, memory management, file systems, input/output systems, and system security. Students will gain practical experience through hands-on assignments and projects that involve implementing and debugging operating system components, understanding concurrency and synchronization, and analyzing system performance. By the end of the course, students will have a solid foundation in how operating systems function, interact with hardware, and provide services for application software, preparing them for advanced courses and real-world system-level programming.

Q1) Describe the difference between a time-sharing system and a real-time system.
Answer: A time-sharing system is a central computer system that is used by multiple users and applications simultaneously.Most of their work is done in batches,using batch processing. A real-time system is an operating system that interacts directly with the user and responds in real time (immediately or almost immediately)with required information. A real-time computer program immediately performs calculations and returns the answer-using sequential processing instead of batch processing.
Q2) Which of the following is a job typically performed by the kernel?
A) managing CPU interactions
B) handling input from the keyboard
C) handling output to the monitor
D) enabling multimedia
Answer: A
Q3) Describe the role of the BIOS on a computer.
Answer: The BIOS is low-level program code that initiates and enables communications with hardware devices,performs tests at startup,such as memory and hardware component tests,called the power-on self test (POST). It also conducts basic hardware and software communications inside the computer and starts a full-fledged operating system that interfaces with the user.
