Inside a Computer System
Har computer ke andar kuch core components hote hain jo mil ke kaam karte hain:
| Component | Kya Karta Hai |
|---|---|
| Motherboard | Main board jahan CPU, RAM, storage aur other components connect hote hain |
| CPU | Instructions execute karta hai — computer ka brain |
| RAM | Temporary working memory. Programs chalne ke dauran active data yahan hota hai |
| PSU | Wall power ko components ke usable electrical power mein convert karta hai |
| GPU | Graphics aur highly parallel calculations process karta hai |
| HDD / SSD | Long-term storage. SSD faster; HDD cheaper per GB |
Key Concept
- RAM = volatile (power off = data gone)
- HDD/SSD = non-volatile (data rehta hai)
- CPU = processing, GPU = graphics/parallel tasks
