For Application data to travel uncorrupted from one host to another, header (or control data), which contain control and adding information is added to the data as it moves down to layer. The process of adding control information as it passes through the layered model is called Encapsulation.Decapsulation is the process of remaining the extra [...]
Networking professional use two networking model to communicate with in the industry-Protocol and the Reference Model. A Protocol Model provides a model that closely matches the structure of a particular protocol suite. The TCP/IP model is protocol model because it describes the function that occur at each layer of protocol with in the TCP/IP suite. [...]
The Physical layer provides the electrical and mechanical interface to the network medium. This layer gives the data link layer its ability to transport a steam of serial data bits between two communication systems, it conveys the bits that move along with the cable. The Physical layer consists of simply the wire or media by [...]
The ISO develop a model what they called Open System Interconnection (OSI).This model proposed that all network protocol should consist of seven distinct layers. SO is multinational body dedicated to worldwide agreement on international standards. The OSI model is not a protocol, it is a model for understanding and designing a network architecture that is [...]
