        ROM ka fullform hai Read Only Memory. Yeh ek aisi memory hai jise keval padha ja sakta hai aur hataya nahi ja sakata.Rom ka upyog multimedia audio,video,images aur vibhinn anuprayogon aur mahatvapurn data file ko mobile ya computer par sangrahit karane ke liye kiya jaata hai.Iska Ek anya mahatva purn kary yah hai ki jab hum computer ya mobile ka upyog karte hai, to bijali ki aapurti band hone ke karan Iska data adrushya(Erase)nahi hota hai. ROM aapke data ko sthayi rup se ya jivan bhar ke liye store kar sakta hai. Ise sthayi Storage Device ke rup me bhi jana jata hai. yeh ek non-asthir memory hai Isliye aapka data computer band hone per bhi surkshit rahata hai, aur yeh lambe samay tak rahta hai.ROM chip RAM ki tulana me bahut sasti hai, aur ROM CPU ka hissa hai.ROM ek sthayi storage device hai.


         ROM ka upyog keval computer me hi nahi kiya jata hai balki kai upkaran hai jinme ROM ka upyog kiya jata hai jaise ki telivision,AC,Mobile phone,washing machine etc.ROM Ek non-volatile memory hai, jiska arth hai ki Ise kabhi bhi hataya nahi ja sakta. jab computer band ho jata hai,to yah memory kaam nahi karti hai,yeh puri tarah se chip me sangrahit hota hai.Aapka computer prarambh,booting prakriya kr raha hota hai tab nirdesh ki aavshyakta hoti hai to un sabhi nirdeshakon ko ROM me sangrahit kiya jata hai, jinke upyog se computer ki booting prakriya puri ho jati hai.

ROM ke kuch Prakar :

1) MROM ( Mask Read Only Memory ) :

         Mask read only memory keval read memory ka sabse purana prakar hai, Isliye Iska upyog aaj ki duniya me kahin bhi nahi kiya jata hai. Yeh ek hardware memory device hai jisme utpadan ke douran nirmata dwara program aur nirdesh sangrahit kiye jate hain, Isliye Ise nirman ki prakriya ke douran kramadeshit kiya jata hai aur fir Ise update, punrsansadhan ya mitaya nahin ja sakta hai.

2) PROM ( Programable Read Only Memory ) :

          Programmable read only memory me ham Ise keval ek baar badal sakate hai. Update hone ke baad aap Ise badal nahin sakate. Upyogkarta khaali PROM ko kharid aur sangrahit kar sakata hai aur usme jankari sangrahit kar sakta hai lekin fir se jankari ko update nahi kar payega, Isliye aapko yaha jankari bharate samay saavdhani se dhyan dena hoga. Ek baar aapne jankari sangrahit kii to aap usse mita (Erase) nahi sakate.

3) EPROM ( Erasable and Programmable Read Only Memory ) :

          Erasable aur Programmable read only memory ek tarah ki memory hoti hai jise mitaya aur fir se store kiya ja sakta hai.yesa karane ki prakriya thodi alag hai, Isliye memory ko 40 minute ultraviolet light madhyam se paas kiya jata hai aisa karnese yeh memory khali ho jaati hai. Hum fir se us memory me jankari store kar sakate hai.

4) EEPROM ( Electrically Erase and Programmable Read Only Memory ) :

           Technology ke naye aavishkaron ne keval memory ko badalne aur fir se store karne ki aavshykata ko janm diya , Is prakar in Electrically Erase aur programmable read only memory ka avishkar kiya. Is memory ki visheshta yeh hai ki hum Ise 10 hajar baar mita aur update kar sakate hai. Is memory me kisi vishesh sthan par mitaya aur update kiya ja sakata hai, Isliye aapko puri jankari ko mitane ki aavshyakta nahi hai.

ROM ke Fayade ( Advantages ) : 

1) ROM ki jankari apane aap nahi badali ja sakati,Jab tak aap Ise nahi badalte.

2) ROM me sangrahit kii huyi jankari kabhi nasht nahi ho sakti.

3) RAM memory , ROM memory ke tulna me adhik vishwasniy hai kyonki RAM me jankari ko mitaya jata hai jab computer ki bijali ki aapurti band ho jati hai.(Erase)

4) Yeh ek sthir memory hai Ise baar baar refresh karne ki aavshykata nahi hai.

5) ROM ko saavdhan purvak sangrahit karane ki aavshykata hai kyonki Ise fir se nahi badala ja sakta hai.


          Friends aapko yeh post kaisa laga? comment karke jarur bataye. ROM ke baare me aur adhik jankari chahiye hogi tabhi comment kr batana na bhule or ye mahatwa purn jankari aap apne friends ke saath bhi share kijiye, Dhanyavad... !!
