Operating System Basics Questions and Answers
Operating System Basics questions with answers are among the most commonly asked in technical interviews and exams. This section covers core OS concepts like process management, memory allocation, file systems, and scheduling algorithms. Practicing programming questions and answers on operating systems helps strengthen your conceptual clarity and practical understanding of computer architecture. Frequently featured in GATE, TCS, Infosys, and Wipro placements, these MCQs provide a balanced mix of theoretical and applied knowledge. Clear explanations make this section an ideal resource for anyone preparing for system-related roles or competitive exams.
