Doston, agar aap computer ya mobile ka use karte hain, toh aapne RAM and ROM ka naam zaroor suna hoga. Jab bhi hum naya phone ya laptop kharidne jaate hain, toh sabse pehle yahi puchte hain ki “Isme kitni RAM hai?” aur “Storage (ROM) kitni hai?”.
Lekin kya aapko pata hai ki what is RAM and ROM aur inke beech asli antar kya hai? Bahut se students jo sarkari exams ki taiyari kar rahe hain, unke liye computer awareness section mein ye topic bahut important hota hai. Aaj ke is article mein hum RAM and ROM ko poori tarah se explain karenge aur 100 MCQs ka base bhi taiyar karenge.
What is RAM and ROM in Computer?
Sabse pehle basic samajhte hain. Computer ho ya mobile, dono ko chalne ke liye memory ki zarurat hoti hai.
- RAM (Random Access Memory): Yeh computer ki “Short-term Memory” hoti hai. Jab aap koi app ya software chalate hain, toh wo RAM mein load hota hai.
- ROM (Read Only Memory): Yeh computer ki “Permanent Memory” hoti hai. Isme wo data hota hai jo computer ko start karne (Booting) ke liye zaroori hota hai.
Full Form of RAM and ROM
Competitive exams mein aksar inki full form puchi jati hai:
- RAM Full Form: Random Access Memory.
- ROM Full Form: Read Only Memory.
Explain RAM and ROM (In Simple Words)
Maan lijiye aap ek office mein kaam kar rahe hain. Aapka Desk jis par aap file khol kar baithe hain, wo RAM hai. Desk jitni badi hogi, aap ek sath utni zyada files khol paayenge. Wahi dusri taraf, aapki Almirah jahan aap files ko store karke rakhte hain, wo ROM hai.
- RAM (Volatile Memory): Iska matlab hai ki agar computer suddenly band ho jaye, toh RAM ka data udd jata hai. Isliye ise “Temporary Memory” kehte hain.
- ROM (Non-Volatile Memory): Isme data hamesha rehta hai, chahe power ho ya na ho. Isliye ise “Permanent Memory” kehte hain.
10 Differences Between RAM and ROM
Agar aap exam ki taiyari kar rahe hain, toh ye table aapko zaroor yaad honi chahiye:
| Feature | RAM (Random Access Memory) | ROM (Read Only Memory) |
| Full Form | Random Access Memory | Read Only Memory |
| Nature | Volatile (Temporary) | Non-Volatile (Permanent) |
| Function | Data access fast hota hai | Data read-only hota hai |
| Usage | Current running tasks ke liye | Booting aur OS ke liye |
| Speed | Bahut fast hoti hai | RAM se slow hoti hai |
| Capacity | 4GB, 8GB, 16GB etc. | 32GB, 64GB, 128GB etc. |
| Cost | Mehangi hoti hai | Sasti hoti hai |
| Data Alteration | Data badla ja sakta hai | Data badalna mushkil hai |
| Type | SRAM, DRAM | PROM, EPROM, EEPROM |
| Visibility | Motherboard par slot hota hai | Chip ke roop mein hoti hai |
Five Difference Between RAM and ROM
- RAM temporary hai, ROM permanent hai.
- RAM fast hai, ROM usse slow hai.
- RAM ka data bijli jaane par delete ho jata hai, ROM ka nahi hota.
- RAM apps chalane ke liye hai, ROM files save karne ke liye.
- RAM mehangi hoti hai aur iski size kam hoti hai (8GB-16GB), ROM sasti hoti hai aur size badi hoti hai (128GB+).
