A Network is a conceptual framework that describes how data and network information are communicated from an application on one computer through network media to an application on other computers in terms of different layers. Network architecture is also known as Reference model. There mainly two classifications of Reference models and are Open and closed.
Open model is one which is open for everyone and no secrecy is there. In a closed model, also known as proprietary system the architecture is kept secret from users. OSI model is an open model while IBM's SNA 7 layer model is a closed system. Here Let's discuss two main reference models OSI model and TCP/IP model.
TCP/IP Model (Internet Architecture):

TCP/IP Model (Internet Architecture):
- TCP/IP ( Transmission Control Protocol/Internet Protocol) defines a large collection of protocols that allow computers to communicate.It has a 4 layer architecture.
- TCP/ IP defines each of these protocols inside document called Requests For Comments (RFCs).
- By implementing the required protocols in TCP/IP RFCs, a computer can be relatively confident that it can communicate with other computers that also implement TCP/IP.
