Hello dosto , kya aapne kabhi socha hai ki jab aap notepad me ya Ms word me apne keyboard se koi bhi ek button press karte hain aur A, B, C ya D jo kuch bhi likhte hain to wo kitna space aapki computer ki hard disk me cover karte hain aur usko save karne par jo file ka size aata hai wo kaise define kiya jata hai. Agar nhi to ye post aapke liye hi hai kyuki is post me main aapko computer ki memory units ke bare me Puri information duga.
Dosto bahut sari chizo ko mapne ke liye kuch units banate gaye hain jaise aapki ghadi me jab aap samay ko mapte hain to waha par second , minutes aur ghante hote hain tab aap time ko maap pate hain , Usi tarike se lambai ko mapne ke liye bhi centimeter, kilometer,kilometer etc hote hain.
Thik isi tarah se jab computer aapki hard disk me kisi space ko mapta hai to waha par bhi kai units hote hain aur inhi units SE milkar kisi file ka size banta hai lekin ab ye banta kaise hai aur ye sabhi units aaye kaha se aur kaise ye decide kiya jata hai ki hamne file me jo bhi name ya koi paragraph type kiya hai to wo kitne MB ya kitne KB ka hoga
To iske liye aapko thodi si technical chizo ko samajhna hoga. Hamara Jo computer hai usme ek electronic circuit hota hai kyuki jab ye Computer banaya gaya tha to isko samjhane ke liye kuch program banaye gaye the aur ye programs binary codes me banaye gaye the.
Ab binary codes kya hote hain to binary codes hote hain "0" aur"1" jisme 0 ka matlab hota hai off aur 1 ka matlab hota hai on. Ab aap sochege ye on , off ka kya chakkar hai to wo ye hai ki ye Jo computer hai wo pura electronic circuits par kaam karta hai aur jab aap binary code se koi program iske andar enter karate hain to aapke sabhi programs ko ye ek electronic circuits me convert kar deta hai
Yani wo jo programs hain wo electronic circuits me convert ho jate hain aur tab computer samajh pata hai ki aap kahna kya chah rhe hain.
Ab jo binary codes me Jo programs likhe jate the wo machine bhasha kahlati thi yani waha par jitne bhi programs hote the wo 01, 01, 01 karke likhe jate the aur ek 0 ya1 ko aap binary digit kahte the.
Ab ye Jo binary digit hain inme jo aapki computer ki memory ka sabse chhota Jo matrak hota hai jise ham "Bit" kahte hain uska space cover karta hai.
Example :- 1 BINARY DIGIT = 1 BIT
Agar aap 0 likhege to ek "bit" hoga or aap 1 likhege to bhi ek "bit" hoga. Is prakar Computer Memory me sabse chhota matrak bit hota hai aur agar aap binary me kuch bhi likhte hain to wo ek "bit" ki jagah cover karega.
Isi tarah se jab 4 "bit" ko mila diya jata hai to ek "nibble" ban jata hai aur 8 "bit" ka jo group hota hai wo "byte" kahlata hai.
Example :- 4 BIT = 1 NIBBLE
8 BITS = 2 NIBBLE = 1 BYTE
Ab "byte" par ham thoda ruk jate hain kyuki Computer me jab aap koi bhi sabd type karte hain to wo ek "byte" ke barabar hota hai yani 8 "bits" ke barabar hota hai
To jab aap computer me koi bhi ek sabd type karte hain to waha par Jo sabd hai abcd computer ko kuch bhi dikhai nhi deta yani man lijiye hamne A likha to computer ko wo kuch is tarah se dikhai dega.
A=01100001
Yani ye Jo binary code hai wahi Computer ko dikhai deta hai aapke dwara type Kia hua sabd nahi.
Example :- Jab ham Notepad me koi blank file save karte hain to uska size 0 "bytes" hota hai aur jab ham ise koi bhi ek letter jaise A likhkar save kar dete hain to iska size 1 "bytes" ho jata hai.
Kyuki ; 8 BITS = 1 BYTE = 1 LETTER
Aur 1 byte me 8 bits isiliye hote hain kyuki jab aap koi ek letter type karte hain to waha par Jo code banta hai wo 8 binary digit ka banta hai aur 8 binary digit ki value 1 byte ke barabar hoti hai , to aasha hai ye chiz aap samajh gaye honge.
Ab chahiye thoda aur jaan lete hain.
Jab 1024 "bytes" mil jati hain to 1 "KB" (kilobyte) banti hai.
Example :- 1024 BYTE = 1 KILOBYTE (KB)
Aur isi prakar se aage ,
Computer ki memory units kya hai
Dosto bahut sari chizo ko mapne ke liye kuch units banate gaye hain jaise aapki ghadi me jab aap samay ko mapte hain to waha par second , minutes aur ghante hote hain tab aap time ko maap pate hain , Usi tarike se lambai ko mapne ke liye bhi centimeter, kilometer,kilometer etc hote hain.

Ab chahiye thoda aur jaan lete hain.
Jab 1024 "bytes" mil jati hain to 1 "KB" (kilobyte) banti hai.
Example :- 1024 BYTE = 1 KILOBYTE (KB)
Aur isi prakar se aage ,
- 1024 KILOBYTE (KB) = 1 MEGABYTE (MB)
- 1024 MEGABYTE (MB) = 1 GIGABYTE (GB)
- 1024 GIGABYTE (GB) = 1 TERABYTE (TB)
- 1024 TERABYTE (TB) = 1 PETABYTE (PB)
To ye Jo kram hai wo aage badhta ja rha hai aur pata nhi future me kitne sare memory ke units aane wale hain lekin sabse chhota Jo memory ka unit hota hai aapke Computer me wo hota hai "bit" aur bit ke bare me Mene aapko puri jankari dedi hai.
To ye thi Computer ki memory units ke bare me full information aur aasha hai aapko ye post jarur pasand aayi hogi.
Agar aapko ye post pasand aayi hai to apne friends ke sath social media par ise jarur share kare.
