Hard Disk Drive Kya Hai. Aaj ke technical yug mein har koi vyakti computer ka istemal karta hai. computer ne hamare roj ke kamo ko aasan kar diya hai. par kya hame pata hai computer ke bare me ! computer kya hai ? kaise kaam karta hai ? iske parts ke bare.

Dosto aaj ke is post me aapko computer ke inhi sawalo me se aapko is post me Hard Disk Drive ki jankari dunga. computer ki hard disk kya hoti hai? yah hard disk kitne type ki hoti? hai aur bhi bahut kuch inke bare me jankari dunga.

hard disk drive kya hai puri jankari

Computer ya laptop me storage ke liye istemal hone wale main unit ko hi hard disk drive kehte hai. yah disk ek aisa computer device he, jo aap ke data ko store kar ke rakhtha hai. waise to yah Hard Drive storage devices hote hai.

HDD Ko Kisne Banaya

Hard disk ko sabse pahle IBM dwara 1956 me launch kiya gaya tha yah hard disk 1960 tak logo ka favourite secondary storage device ban gaya tha.

Hard disk drive ko sabse pahle 1956 me data storage ki traha IBM Real Time Transaction computer main use kiya gaya tha, aur usi samay thode time bad isko general purpose ke liye mini computer aur mainframe computer ke liye develope kiya gaya aur IBM ke dwara banaya gaya pahile hard disk ka size kewal 5 MB ka tha aur iski height 5 fridge ke barabar aur weight 250 KG tha, yah drive 5 million six-bit character store kar sakti thi.

Hard Disk Drive me ek circle shape magnetic disk hoti hai jo bahut teji se ghumti hai jiski speed 7000 RPM hoti hai iske speed ko hum RPM (Revolutions Per Minute) me mapte hai. jisme digitally  data  save hota hai aur simple si bat hai jitni jyada RPM speed utni hi jyada data ko read and write karne ki capacity hoti hai.

HDD Data Store Karne wale Unit Ko Kaise Ginte Hai

1024 B = 1KB = (Kilo Byte)

1024 KB = 1MB = (Mega Byte)

1024 MB = 1GB = (Giga Byte)

1024 GB = 1TB = (Tera Byte)

1024 TB = 1 PB  = (Peta Byte)

1024 PB = 1 EB = (Exa Byte

1024 EB = 1 ZB = (Zetta Byte)

1024 ZB = 1 YB = (Yotta byte)

1024 YB = 1 BB = (Bronto byte)

1024 BB = 1 GB = (Geop byte)

Digital media me data ko in unit ke aadhar par gina jata hai. me aapse ek bat kahna chahta hu. jis tarha 16 GB ya 32 GB ham kahte hai. unmese ham  pure space ka istemal nahi kar sakte kyuki unme se kuch space pahle hi system ke liye use ho jati hai. iska reason yeh hai, jab bhi ham 32 GB Memory ka istemal karte hai. tab hame sirf 28 GB ya usse thoda kam space hi milta hai.

dosto maine aapko upar Hard Disk Drive kya hoti hai? aur iske bare me thodi jankari di ab ham janege iske types ke bare me.

Hard Disk Drive Ke Prakar

1] PATA Hard Disk (IDE Intregrated Drive Electronic)

Pata hard disk ko IDE (Intregrated Drive Electronic) ke nam se bhi jante hai. Pata ka full form Parallel Advance Technology Attachment hai. IDE Pata Drives me 40th pins hote hai. aur yah 8 Bit data ek bar me send karta hai. IDE Pata Drives hame 133 MB per second rate transfer karne ki suvidha deta hai. hame pata cable me do alag alag cable connect karne ko milte hai. in cable ko ham alag nam se jante hai. pahile cable ka naam master aur dusre cable ka naam slave hota hai.

2] SATA Hard Disk (Serial Advance Technology Attachment Drive)

Sata Ka full form Serial Advance Technology Attachment hai is drive me 7 pins hoti hai. inme se 4 pin 2 slot ke liye work karti hai. aur file ko send aur recive karne me madad karti hai. sata driver per second me 300 MB tak ke data ko transfer karti hai. sata cable ko sata hard disk jodne me istemal kiya jata hai. isse kewal ek hi drive ko joda ja sakta hai.

3] SCSI Drive (Small Computer System Interface) Hard Disk

SCSI ko American national standard institute ANSI dwara iske disk drive ko computer ko attach karne ke liye banaya gaya tha. iska pahla version 8 Bit ka tha jo 5 MB tak data bhej sakta hai SCSI Drives me usually 50 se 60 pins hote hai. aur yah 640 MB per second data transfer kar sakta tha ek SCSI cable kam se kam 16  drivers ko connect kar sakta hai.

4] SAS Hard Disk (Serial Attached SCSI) Drive

Is drive me 805 MB data per second transfer karne ki capacity hoti hai. iski cable ke sath ham maximum 128 drive ek sath connect kar sakte hai.

External Hard Disk Kya Hai

External Hard Disk Drive un Hard disk ko kahte hai. jinhe ham apne sath kahi bhi le ja sakte hai, jaise laptop, pendrive, etc yah portable hote hai. usi tarha External HDD bhi portable devices hote hai, jise ham kahi par bhi computer ya laptop me connect kar ke inka kahi bhi istemal kar sakte hai.

SSD Kya Hai

SSD ka matlab Solid State Drive hota hai yah ek non-volatile storage device hai, hard disk me disk ghumti hai, lekin SSD me chip hoti hai, jo memory card aur pendrive ki tarha kam karti hai. yah data ko cheap me store kar ke rakhti hai. isme koi bhi drive nahi ghumti isme kisi physical ghumne wali drive nahi hone ke karan SSD ki speed HDD ki speed se kai guna jyada tez hoti hai.

Advantage of SSD

  • Kam bijli ki khapat.
  • lambe samay tak chalti hai.
  • mini size aur halka vajan.
  • SSD ki speed 500 MB per second hoti hai.

Disadvantage of SSD

  • costly hoti hai.

aajkal ke jyada tar Ultrabook me hame SSD milti hai. jaise Apple ka mac book air

Friends maine aaj aap sabhi ke sath Hard Disk Drive Kya Hoti Hai iski jankari share ki hai ummid karta hu aapko meri yah post bahut jyada pasand aayi hogi
