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.
Full File Systems guide →A FAT (file allocation table) based file system is being used and the total overhead of each entry in the FAT is 4 bytes in size. Given a 100 106 bytes disk on which the file system is stored and data block size is 103 bytes, the maximum size of a file that can be stored on this disk in units of 106 bytes is …
