Physical Layer (物理层) Two types of Internet domain sockets: stream sockets (= TCP sockets) provides communication in connected mode guarantees reliable data transmission| costs time in connection set-up and error checking datagram sockets(=UDP socket) provides communication in connectionless mode does...
OSI模型-功能,原理和层次(The OSI Model - Features, Principles and Layers) There arennumbers of users who use computer network and are located over the world. So to ensure, national and worldwide data communication, systems must be developed which are compatible to communicate with each other ISO...

The Open Systems Interconnection (OSI) model describes seven layers that computer systems use to communicate over a network. The OSI model is divided into seven distinct layers, each with specific responsibilities, ranging from physical hardware connections to high-level application interactions. Each la...
a system-wide failure and you're not sure where to find the problem, the OSI layers could help. And if you're working with a vendor that sells something very specific that works on just one part of your system, you could talk about that application in shorthand with the OSI model. ...
The physical layer in OSI Model is the lowest layer. It includes physical equipment, such as switches and cables, that is required in the process of data transfer. The physical layer transfers unstructured, raw data bits, between the physical layers of the sending and the receiving device, eit...
OSI Model Explained: The OSI 7 Layers We’ll describe OSI layers “top down” from the application layer that directly serves the end user, down to the physical layer. 7. Application Layer The application layer is used by end-user software such as web browsers and email clients. It provide...

This tutorial explains the OSI reference model. Learn the seven layers of the OSI model and the functions of each layer in detail through examples.
Data moves bi-directionally through the OSI model; each layer communicates with the layers below and above it in the stack. Furthermore, both the sending and receiving devices transmit data through the data layers; and senders and receivers often switch roles in the process. ...
