What is RAM?
Random Access Memory (RAM) ek volatile memory hai — matlab power off hone pe data erase ho jaata hai. Ye short-term memory ki tarah hai. CPU RAM se data read/write karta hai — storage (HDD/SSD) se bahut zyaada fast.
Agar aap 10 apps ek saath kholen hain, sab RAM mein hain. Ek app close karo, RAM free hota hai.
How Does RAM Work?
App Launch Karo
Jab aap koi program open karte ho, OS uski files storage (SSD/HDD) se RAM mein copy karta hai.
CPU Data Access Karta Hai
CPU RAM se data read karta hai — storage se 100x-1000x faster. Isliye RAM speed matters karta hai.
Data Active Rehta Hai
Jab tak app open hai, data RAM mein active rehta hai — instant access ke liye ready.
App Close Karo
App band karne pe RAM free ho jaata hai — dosra program use kar sakta hai wo memory.
