Boot block in Linux in hindi

Boot block, jo ki “boot sector” ya “master boot record” ke roop mein bhi jana jata hai, ek important concept hai jo primarily hard drives aur removable media (jaise USB drives) par paya jata hai. Yeh block system ke boot process ko trigger karta hai. Chaliye samjhein ki Linux mein boot block kya hota hai:

Boot block in Linux in hindi

  1. MBR (Master Boot Record): Linux, jaise anya operating systems, MBR ka istemal karta hai booting ke liye. MBR ek chhota data block hota hai jo hard drive ke pehle sector (sector 0) par store hota hai.

  2. Boot Loader: MBR mein ek boot loader hota hai, jaise GRUB (GRand Unified Bootloader) ya LILO (LInux LOader). Boot loader ek small program hota hai jo OS kernel ko load karne aur booting process ko initiate karne ke liye istemal hota hai.

  3. GRUB (GRand Unified Bootloader): GRUB ek commonly used boot loader hai jo Linux systems par istemal hota hai. Yeh boot loader menu provide karta hai jahan se aap different operating systems aur kernels ko select kar sakte hain. Yeh menu user-friendly hota hai aur dual-boot systems ke liye bhi achha kaam karta hai.

Booting Process in Linux:

Jab aap apne computer ko start karte hain, to boot block (MBR) activate hota hai. Iske baad, boot loader (jaise ki GRUB) initialize hota hai. Boot loader user ko multiple options deta hai jahan se woh OS select kar sakta hai. User apne preferred OS (jaise Linux) ko select karta hai.

Boot loader kernel image ko load karta hai. Kernel image ek crucial part hota hai jo operating system ka core hota hai. Yeh kernel image memory mein load hota hai aur system initialization process start hoti hai. Linux kernel memory management, file systems, device drivers, aur aur bhi bahut kuch control karta hai.

Boot block ya MBR system ki pehli step hoti hai jahan se booting process shuru hoti hai. Iske baad, kernel load hota hai aur system ready ho jata hai user ke commands aur applications ko run karne ke liye.

Linux ke boot block ka primary role yeh hai ki woh boot loader ko initialize kare aur operating system kernel ko load kare. Iske alawa, MBR booting process ko start karne wale devices ko bhi identify karta hai, jaise ki hard drives ya USB drives.
