ROM kya hai or kitne prakar hai (MROM, PROM, EPROM, EEPROM

Dosto aplog kaise hai ummit kart ahu ki aplog sab tik hunge friends aj ka post me aplog ko me batane wala hu ki Rom kya hai or kitne prakar hai aiye suru karte dosto ROM ka nam to aplog ne sunai hoga jab ham mobile , laptop or computer buy karte hai to sabse pahle RAM or ROM ke bareme pata karte hai. to bas wahi ROM ke  bare me aplog ko batane wala hu.

ROM ke bare me jankari dene se pale apko memory ke bare me thoda bata deta hu ki apko ROM samjne me asan ho jayegi.

Memory kya hai

Computer memory hamare brain ki tarh hi hote hai. yani data or information ko store karne or yad rakhne me sakxam hota hai. computer memory ko storage ke capacity memory package ke types ke upper nirbhar karta hai. input device duwara computer me data or information storage media ke jariye se stor kiya jata hai. ishi storage media ko ham memory kahte hai. Computer memory ko chote – chote hisso me bata gaya hai or har hisse ka size saman rahta hai. computer memory ke in hisso ko cell bola jata hai or har ek cell ka ek – ek address jarur hota hai. jisse memory address bola jata hai yah address 0 se start hota hai.

Memory 3 type ke hote hai

  • Primary memory
  • Secondary memory
  • Cache memory

Dosto aj ke ye post me sabse pahle me primary memory ke bare me batauga.

Primary memory

Jo Data and Information ko computer abhi ishtomal karta hai ushi data ko primary memory store karke rakhta hai. primary memory koMain Memory vee kaha jata hai. iski storage capacity ya memory space limited rahti hai jab tak computer me power supply hota hai tab tak ya data ko rakhta hi jab power supply band ho jata hai to data erase ho jata hai. jata hai. example ke tor par me batata hu – ager ham computer me kuch kam kar rahe hai or light chala jaye to kam kar rhe data sab gayab ho jata hai. computer ke onder ki sari data memory me hi process hota hai primary memory 2 prakar ki hoti hai.

ROM kya hai (what is ROM in Hindi)

Ishka pura nam hai read only memory ishke nam se ap andaj laga sakte hai ki ham bas ishe read kar sakte hai ROM hamare mobile, computer , laptop me lagi hui rahti hai inshe ham permanent storage vee kah sakte hai ishme fixed program rahte hai jinhe badalna asan nhi hota . dosto ishe samjne ke liye apko ek example deta hu ham jab computer kharidte hai to usme BIOS ( Basic input output system) program pahle se hi rahte hai ya program computer ko on karne me help karta hai. jish memory me BIOS rahta hai wahi memory ROM kahlata hai. ROM ko ham externally vee laga sakte  hai jaise ki mobile me chif ke rup me or computer me pen drive ke rup me badlte huye technology ke sath ROM vee badal rah hai. to chaliye dosto ab ROM ke prakar ke bareme  jankari deta hu.

ROM 4 prakar ke hote hai

  • Masked Read Only Memory(MROM)
  • Programmable Read Only Memory(PROM)
  • Erasable Programmable Read Only Memory(EPROM)
  • Electrically Erasable Programmable Read Only Memory(EEPROM)

Learn about all these in detail now.

1.MROM

Ishka pura nam hai Masked Read Only Memory . Aj ke jamane me iska ishtomal bilkul vee nhi hota hai. ya sabse pahle or sabse purana ROM hai. jisme pahele se hi data stored kiya jata hai. jise change karna ya update karna possible nhi hai. yahi bajay hai ki ajkal ishka ishtomal nhi hota hai.

2.PROM

Ishka pura nam hai Programmable Read Only Memory or ishe one time Programmable Read Only Memory (PROM) vee bola jata hai. ishko bas ham ek bar update kar sakte hai ya program dal sakte hai. purana ko hatakar dobara kuch new dalna isme possible nhi hai. ishme chote fuse hote hai jinme Instruction dala jate hai. wah vee programming ke jariye hi users khud ke liye blank ROM kharite hai or khud ke hisab se unko jo instruction or program dalna hota hai.

3.EPROM

Ishka pura nam hai Erasable Programmable Read Only Memory.ishko ham erasekarke phir se programmed kar sakte hai. matlab ki purana instruction ko mita kar phir se new program usme dal sakte hai. ishko erase karne ke liye hame UV Rays ( ultraviolet rays ) ki requirement hoti hai. 40 minuet tak rays se pass karne ke bad ishki puri data erase hoti hai or phir ham usme phir se instruction or program dal sakte hai. ishka kam ko karne ke liye EPROM Eraser ka vee ishtomal kiya jata hai charge ishke onder programming karte samay dala jata hai. ya charge maximum 10 years se adik samay tak rakha jata hai. kyoki bahr nikalne ka koi rasta nhi hai to wah memory ke onder hi rah jata hai. ishi charge karne ke liye ultraviolet light ko quartz crystal window ke  madyam se pass kiya jata hai. ish light ke prabhab se hi sab charge erase ho jata hai Click here

 4.EEPROM

Ishka pura nam hai Electrically Erasable Programmable Read Only Memory.jaise-jaise Technology me badlab ate rahte hai ROM me vee waise badlawa ate gaye  hai ish ROM ko ham hajaro bar khali karke hajaro bar phir se ishme instruction dal sakte hai. ya computer ke motherboard se juda hota hai. ishme ham kisi vee data ko read kar sakte hai , erase kar sakte hai or phir se programmed vee kar sakte hai or ishme yah jaruri nhi ki ham pure chif  ko khali kare ham apni jarurat ke anusar location choose karke erase or programmed kar sakte hai.

ROM ki  Attributes

  • ROM ek permanent memory hoti hai.
  • Basic Functionality ke Instructions store rhte hai.
  • Kebal Readable hoti hai.
  • RAM ki comparison me sasti hoti hai.
  • C P U memory ka bhag hoti hai.

ROM ishtomal karne ke kya phaide hai (Advantage Of ROM )

Yah RAM  Se jyada sasta hota hai. RAM se jyada bharosa ish par kiya ja sakta hai kyoki power supply band hote hi RAM ka data chala jata hai lekin ROM ka data nhi jata hai ishe bar – bar refresh karne ki jarurat vee nhi hai kyoki Stable hai. ishke data apne ap nhi badlte user jab badlenge tab hi ishke data badlte hai . ishme data ko bahut shoch samjkar dalna padta hai kyoki ham bar – bar nhi badal sakte . yeh program ke ishthai rep se rakhta hai , ROM non volatile prakiya hai.

My final opinion on this article

 Aj me yesh post me  (Read Only Memory) ROM kya hai (what is ROM in Hindi)ushke bat ROM ke prakar (Types Of ROM- MROM, PROM, EPROM, EEPROM) ke bare me jankari di gai hai. ending me ROM ke Advantages Of ROM ke bare me bataya hu. Dosto jaise – jaise Technology badalta ja raha hai ROM me ishtomal hone wali Technology vee badalti ja rahi hai.jaise  Mobile, Computer, Laptop yah sab ki Storage Capacity vee badti ja rahi hai.

Dosto ROM se related ish article se aplog ko samjane ki kosish kiya hu ager ye mera post ap ko helpful lage to  comment jarur kare or mera  Incentive badane ke liye mere post ko dosto ke sath social media ke madyam se share kare jaise whatsapp , facebook , Instagram etc . computer tips or technology se sambhandit jankari pane ke liye mere tagifind.com blog ko subscribejarur karethanks all
