1. GRUB ka full form kya hai?
GRUB = Grand Unified Bootloader
- Grand: Matlab bada/important
- Unified: Sab kuch ek saath (combine karke)
- Bootloader: Wo program jo computer on hote hi sabse pehle chalti hai aur decide karti hai kaunsa operating system load hoga (jaise Windows, Ubuntu, etc).
2. GRUB ka kaam kya hai?
- Jab aap computer on karte ho, to sabse pehle GRUB aata hai.
-
Agar aapke computer mein ek se jyada Operating System hain (Windows + Linux), to GRUB aapko poochta hai:
- "Kaunsa OS chalana hai?"
Wo ek menu jaisa dikhata hai, jisme aap select kar sakte ho.
Jaise ghar ka gatekeeper decide karta hai kaun andar aayega, waise hi GRUB decide karta hai kaunsa system start hoga.
3. Naam GRUB hi kyon rakha?
- Bootloader word pehle se industry mein use ho raha tha — iska kaam hai “boot” yani start karna.
- Developers ne socha ek aisa bootloader banaye jo sab OS (Linux, Windows, etc) ko ek hi menu mein dikha sake — isliye "Unified" word use kiya.
- Thoda mazak-mazaak mein "Grand" laga diya, ki bhai, ye to sab bootloaders ka baap hai.
- Isliye Grand Unified Bootloader, jiska short form bana GRUB.
Mazedar Tarike se:
- GRUB ek waiter ki tarah hai, jo poochta hai — "Aapko kaunsa khana (OS) chahiye?"
- Aap order do, wo serve kar dega!
Summary Table:
| Naam | Full Form | Kaam | Nomenclature Reason |
|---|---|---|---|
| GRUB | Grand Unified Bootloader | OS select aur boot karna | Sab OS ko ek jagah, Grand matlab best! |
