ISO/OSI Model By-Biswajit Bhunia, Education Helper  OSI or Open System Interconnection হলো একটি Networking এর মডেল। Why Model  required for Networking?[ Networking এর জন্য কেনো Model দরকার?]      বাড়ি বানাতে গেলে যেমন Plan তৈরি করতে হয়, Bridge বানাতে গেলে যেমন Plan তৈরি করতে হয়,                সেরকম Networking এর জন্য দরকার Plan or Model.
