Hard Disk ek storage device hai jo data ko store karne ka kaam karti hai. Yeh computer system ka ek important component hota hai, jisme data long-term storage ke liye rakha jata hai. Hard Disk kaam kaise karti hai aur isme kon-kon se parts hote hain, iske baare mein kuch basic jaankariyan niche di gayi hain:

  1. Platters (Disks): Hard Disk mein ek ya multiple circular disks hote hain, jo ki magnetic coating se cover hote hain. Yeh platters data ko store karte hain.
  2. Read/Write Heads: Har platter ke dono sides par ek read/write head hota hai. Yeh head magnetic charge ko read ya write karta hai. Read/Write heads electromagnetic hoti hain aur platter ke surface ke bohot kareeb hoti hain.
  3. Actuator Arm: Actuator arm, read/write heads ko platter ke upar lekar layega ya niche le jayega. Iske movement se data read or write hota hai.
  4. Spindle: Spindle platters ko rotate karta hai. Platters ek spindle ke around ghumte hain, jisse read/write heads apne specific positions par data access kar sakein.
  5. Controller Board: Hard Disk ka control board data transfer ko manage karta hai. Yeh board interface provide karta hai jisse hard disk ko computer ke saath connect kiya ja sake.
  6. Cache: Hard Disk mein ek small memory cache hota hai jo frequently accessed data ko temporary store karta hai, jisse data access speed improve hoti hai.

Hard Disk kaam kaise karta hai:

Jab aap computer se kisi file ya program ko access karte hain, toh CPU read/write commands generate karta hai. Yeh commands controller board ke through read/write heads tak pahunchte hain. Read/write heads magnetic charge ko detect karte hain aur data ko read ya write karte hain.

Yadi aap kisi file ko access karte hain, toh read/write heads us file ke location tak jaakar data ko read karte hain aur use CPU ko provide karte hain. Similarly, agar aap kuch save karte hain, toh data write process hota hai, jisme data platters par magnetic charges ke form mein store hota hai.

Is tarah se, hard disk data ko store aur access karne mein madad karta hai, jisse aap apne computer mein files, programs, aur operating system ko save aur run kar sakte hain.
