Magnetic media in computer network in hindi

Magnetic media ek prakar ka storage media hai jiska upyog data ko store aur transmit karne ke liye kiya jata hai. Isme magnetic particles ka istemal hota hai jo magnetic fields ke prabhav se data ko encode, store, aur retrieve karte hain. Kuch pramukh examples of magnetic media hai:

  1. Magnetic Tapes: Magnetic tapes ek long and narrow plastic tape hai jisme magnetic coating hoti hai. Data ko magnetic particles ke magnetic orientation (alignment) ke through encode kiya jata hai. Magnetic tape storage systems high capacity aur cost-effective storage provide karte hain. Isme data sequential access ke saath stored hota hai, jisse data retrieval speed me limitation hoti hai. Magnetic tapes ka istemal backup, archival storage, aur data transfer ke liye kiya jata hai.

  2. Hard Disk Drives (HDD): Hard disk drives magnetic media ka istemal karte hain data storage ke liye. HDDs mei ek rotating platter hoti hai jisme magnetic coating hoti hai. Platter par magnetic heads hote hain jo data read aur write karte hain. HDDs high capacity, fast data access speed, aur random access capability provide karte hain. Hard disk drives commonly istemal hota hai personal computers, servers, aur data storage systems mein.

  3. Magnetic Disks: Magnetic disks floppy disks aur magnetic diskettes ke roop mein prasiddh hai. Ye thin, flexible plastic disks hote hain jisme magnetic coating hoti hai. Floppy disks small amount of data storage ke liye use hote the, lekin ab bahut kam istemal hote hain.

Magnetic media data ko magnetic fields ke through store aur retrieve karne ke liye kam karte hain. Data encoding, writing, aur reading magnetic particles ke magnetic properties aur alignment par depend karta hai. Isme data storage ka advantage hai ki data persistent rehta hai, yani ki power loss ke baad bhi stored data retained rehta hai. Lekin, magnetic media sensitive hote hain external magnetic fields ke prati, aur mechanical failures ya magnetic interference ke karan data loss ka khatra hota hai.

Magnetic media ke alawa, non-volatile storage media jaise ki solid-state drives (SSDs) aur optical discs (jaise CDs aur DVDs) bhi upyog hote hain data storage ke liye.
