Computer me internal memory aur external memory dono important components hote hain jo information storage aur processing ke liye use hote hain. Yahan pe thoda detail me explain karta hoon:

Internal Memory (Primary Memory):

RAM (Random Access Memory): Ye temporary storage provide karta hai computer ko. Jab aap koi application chalate hain, ya koi file open karte hain, tab ye data temporarily RAM me store hota hai. Jab aap computer ko restart karte hain, RAM ka data erase ho jata hai.

ROM (Read-Only Memory): Ye permanent storage hai. Isme essential system files aur instructions hote hain jo computer ke proper functioning ke liye zaruri hote hain. Isme data read-only hota hai, matlab aap ise overwrite nahi kar sakte.

External Memory (Secondary Memory):

  1. Hard Disk Drive (HDD): Ye ek physical device hota hai jisme long-term data storage hoti hai. Yeh files, applications, aur operating system ka data store karta hai. HDDs large storage capacity provide karte hain.
  2. Solid State Drive (SSD): SSD bhi ek type ka external memory hai, lekin isme data ko flash memory chips pe store kiya jata hai. SSDs traditional HDDs se faster hote hain aur reliable bhi hote hain, lekin thoda costly ho sakte hain.
  3. USB Drives (Pen Drives): Ye portable external memory devices hote hain jo aap computer ke USB ports me connect karke use kar sakte hain. Inme data storage ka capacity choti hoti hai lekin inko easily carry kiya ja sakta hai.
  4. Memory Cards: Inko mainly cameras, smartphones, aur other portable devices me use kiya jata hai. Inme bhi data storage hoti hai aur inko devices me easily insert karke data transfer kiya ja sakta hai.

In summary, internal memory mainly RAM aur ROM ko refer karta hai jo direct access ke liye use hota hai, jabki external memory HDDs, SSDs, USB drives, aur memory cards jaise devices ko refer karta hai jo long-term data storage ke liye use hote hain.
