GATE Operating System: File Systems and Disk Performance – Previous Year Questions
10 GATE previous year questions on File Systems and Disk Performance (Operating System, Computer Science) with answers and explanations, from every paper.
- GATE 2016 CS Q58 – Consider a disk queue with requests for I/O to blocks on cylinders 47, 38, 121, 191, 87, 11, 92, 10. The C-LOOK scheduling algorithm is used. The head…
- GATE 2015 CS Q54 – Consider a disk pack with a seek time of 4 milliseconds and rotational speed of 10000 rotations per minute (RPM). It has 600 sectors per track and…
- GATE 2015 CS Q56 – Suppose the following disk request sequence (track numbers) for a disk with 100 tracks is given: 45, 20, 90, 10, 50, 60, 80, 25, 70. Assume that the…
- GATE 2019 CS Q52 – The index node (inode) of a Unix-like file system has 12 direct, one single-indirect and one double-indirect pointers. The disk block size is 4 kB,…
- GATE 2026 CS (CS2) Q53 – To keep track of free blocks in a file system, the linked-list approach is used. The disk size is 16 GB, the block size is 2 KB, and block numbers are…
- GATE 2026 CS (CS1) Q59 – Consider a hard disk with a rotational speed of 15000 rpm. The time to move the read/write head from a track to its adjacent track is 1 millisecond.…
- GATE 2025 CS (CS1) Q51 – A disk of size 512M bytes is divided into blocks of 64K bytes. A file is stored in the disk using linked allocation. In linked allocation, each data…
- GATE 2022 CS Q63 – Consider two files systems A and B, that use contiguous allocation and linked allocation, respectively. A file of size 100 blocks is already stored in…
- GATE 2021 CS Q25 – Consider a linear list based directory implementation in a file system. Each directory is a list of nodes, where each node contains the file name…
- GATE 2020 CS Q45 – Consider the following five disk access requests of the form (request id, cylinder number) that are present in the disk scheduler queue at a given…
