File Accessing Methods in Operating System - Sequential, Direct and Indexed

Learn about the three fundamental file accessing methods used in operating systems through this 11-minute educational video. Explore sequential access, where files are read or written in a linear order from beginning to end, direct access that allows jumping to specific file locations using addresses or positions, and indexed access which uses index structures to efficiently locate and retrieve data. Understand how each method works, their advantages and disadvantages, and when to use each approach in different computing scenarios. Gain insights into how operating systems manage file access patterns and optimize data retrieval based on application requirements and storage characteristics.
