Topic notes
File systems and secondary storage in GATE CS are predominantly tested through numerical calculation problems (NAT/MCQ) involving disk geometry, timing analysis, and block allocation schemes. The questions focus on low-level mechanics: rotational latency, seek time, track transfer overhead, inode/FAT/linked pointer calculations, free space management, and disk scheduling algorithms. A smaller subset tests conceptual directory operations and allocation fragmentation properties.
