Computer Networking ke Goals aur Applications

 Computer Networking ke Goals

Chaliye ek-ek karke samajhte hain:

 1. Resource Sharing 

Goal: Printer, scanner, software, aur files ko ek saath use karna.

Example: College lab mein sabhi students ek hi printer use karte hain.

Goal: Agar ek system fail ho jaye to doosra system kaam continue kare.

Example: Bank ka ek server down ho gaya to backup server automatically kaam chalu kar deta hai.

 3. Cost Saving

Goal: Paise bachana by sharing devices and software.

Example: 10 computers ke liye alag printer lene ke bajaye ek printer sab ke liye kaafi hai.

 4. Scalability 

Goal: New device ya user ko network mein add karna easy ho.

Example: College Wi-Fi mein naye student ka laptop connect ho jata hai bina extra setup ke.

• Remote servers pe simulations run hote hain

 7. Internet Services

• Websites, YouTube, Google, Facebook – sab network pe chalte hain
