The OSI model was created to impose a standardised from of networking, For example, you a device on your network can have the same IP as one on your
We use the concept of layers in our daily life As an example, let us consider two friends who communicate Figure 2 2 Seven layers of the OSI model
Protocols, or rules, can do their work in either hardware or software or, as with most protocol stacks, in a com- bination of the two The nature of these
The seven layers of the OSI reference model, are concerned with tasks known protocols for the network layer include the Internet Protocol (IP), the
The OSI Networking Reference Model Lesson overview In OSI model layers functions and protocols BytesofGigabytes Network Layers Explained OSI TCPIP
Network models are organized into layers, with each layer representing a specific networking function These functions are controlled by protocols, which are
OSI layers 9 Implementation of the Layers • Well-defined interfaces and layer functions provide modularity to a network (encapsulation)
network types, such as Ethernet, Frame Relay, and ATM Figure 2–1 shows the OSI Seven Layer Model When we talk about Layer 2 and Layer 3 networking, it is
standard that covers all aspects of network communications is the Open Systems Interconnection (OSI) The interaction between layers in the OSI model
It separates the functions of protocols into manageable layers Each layer performs a specific function in the process of communicating over a network The TCP/
