Super block in Linux in hindi

Super block Linux filesystems mein ek important data structure hota hai, jo filesystem ke metadata aur configuration information ko store karta hai. Super block, filesystem ke initialization, mounting, aur disk I/O operations ke liye critical hota hai. Linux mein filesystems ke liye multiple super blocks hote hain.

Super block in Linux in hindi

Yahan, main super block ke key components aur unka kaam samjhata hoon:

  1. Filesystem Type Information: Super block filesystem ka type (jaise ki ext4, xfs, ntfs, etc.) aur version ko store karta hai.

  2. Inode Information: Super block inode count aur inode size ko maintain karta hai. Inodes filesystem mein files aur directories ki metadata (permissions, ownership, timestamps, etc.) ko store karne ke liye istemal hote hain.

  3. Block Size: Filesystem ka block size yani data ko store karne ke liye allocate kiya gaya unit, super block mein specify hota hai.

  4. Block Count: Super block filesystem ke total blocks ko maintain karta hai. Yeh information filesystem ke size aur capacity ko represent karta hai.

  5. Free Block Count: Yeh count bataata hai ki filesystem mein kitne blocks khali hain, jinme data store kiya jaa sakta hai.

  6. Free Inode Count: Super block bataata hai ki filesystem mein kitne inodes khali hain, jinme files aur directories create kiye jaa sakte hain.

  7. Mount Information: Super block mount point (jahan filesystem ko mount kiya gaya hai) aur mount options (jaise read-only ya read-write) ko track karta hai.

  8. Last Mount Time: Yeh timestamp bataata hai ki filesystem ko kab aakhri baar mount kiya gaya tha.

  9. Last Write Time: Super block aakhri baar filesystem par data write kiye gaye the us time ko maintain karta hai.

  10. Error Handling Information: Super block filesystem ke consistency ko maintain karne ke liye error handling information bhi store kar sakta hai.

Super block filesystem ke basic parameters aur configuration information ko track karta hai, jo filesystem ke proper functioning ke liye important hoti hai. Filesystem initialize hote waqt, operating system super block ko read karke filesystem ko mount karta hai, taki aap usme data read/write kar sakein. Disk I/O operations ke dauraan, super block filesystem ke consistency ko maintain karne mein madadgar hota hai.
