The "network layer" is the part of the Internet communications process where these connections occur, by sending packets of data back and forth between different networks. In the 7-layer OSI model (see below), the network layer is layer 3. The Internet Protocol (IP) is one of the main...
OSI is a communications reference model to help conceptualize how data can be transmitted and received on a network. The model consists of seven distinct layers forming astack. Each layer in the stack is performed in a step-by-step manner: first, moving up the stack during data transmissions ...

The application layer is the seventh layer in the OSI model. Though the name might be deceiving, it’s not an actual application; rather, it’s a component within an application that manipulates information. It’s essentially designed to provide network services to the end user. Users can tra...
Dive deep into the OSI Model to understand its seven layers, their functions, and how it defines the networking framework to implement protocols in seven layers.
In this article, we will talk about the much-asked query of what is layer 2 network is and how its works in a typical network. We will also briefly touch on the basic concepts regarding this topic. The data link layer of the OSI model is sometimes called the MAC layer. It's ...
The transport layer is the fourth layer in the OSI model, which is responsible for point-to-point communication on the network. Put simply, the transport layer provides logical communication between the application processes running on different hosts. The transport layer contains a set of documents...
这是人类历史上首次以法规的形式限制二氧化碳等温室气体排放,以控制日趋严重的温室效应。(1)绿色植物通过__作用吸收CO 2 ,通过__作用将CO 2 释放到大气中。(2)科学家采取“组合转化"技术,将CO 3 和H 3 以一定比例混合,在一定条件下反应,生成一种重要的化工原料和水,反应的化学方程式如下,请在括号中...
1. Physical Layer The Physical Layer is responsible for the physical connection between devices. It defines the hardware elements involved in the network, including cables, switches, and other physical components. This layer also specifies the electrical, optical, and radio characteristics of the netwo...
This is the lowest layer of the OSI reference model. For transmission, it defines all the procedures and functions that physical devices and interfaces have to perform. It is physical and tangible as well. However, it does not deal with the actual physical medium (like fiber, copper). ...
