حيث تشرق شمس الإبداع بلا شعاع ويصطر الأمل بسمة الحياة وأن طريق الخلود الفناء و الهلاكـ سبب البقاء فهذه الحياة وهذه الدنيا أمورٌ متناقضة وحكايات زائلة للأسف الشديد
The Open System Interconnection Reference Model (OSI Reference Model or OSI Model) is an abstract description for layered communications and computer network protocol design. It was developed as part of the Open Systems Interconnection (OSI) initiative. In its most basic form, it divides network architecture into seven layers which, from top to bottom, are the Application, Presentation, Session, Transport, Network, Data-Link, and Physical Layers. It is therefore often referred to as the OSI Seven Layer Model.
