Network-to-network connections are what make the Internet possible. 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 lay...
Located at Layer 3 of the Open Systems Interconnection (OSI) communications model, the primary function of the network layer is to move data into and through other networks. Network layer protocols accomplish this goal by packaging data with correct network address information, selecting the appropria...
The function of the network layer is to provide an end-to-end communication capability to the transport layer, which lies above it as shown in Figure. The OSI reference model specifies that the transport layer need not know the method by which the network layer performs communication...
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 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...
The session layer handles opening and closing network communications between two interacting devices. The “session” refers to the time between the opening and closing of the interaction. The session layer makes sure the session is open for a long enough period of time for all the necessary data...
What layer converts data into Packets? AA. NetworkB. ApplicationC. PhysicalD. Data Link 相关知识点: 试题来源: 解析 A 根据OSI模型,各层功能如下: - **A. Network层(网络层)**:负责将传输层的**数据段(Segments)**封装为**数据包(Packets)**,并实现路由选择和逻辑寻址。 - **B. Application...
A wide area network (WAN) is any network that extends over a large geographic area, usually connecting multiple local area networks (LANs). Learning Center Network layer How Internet works Networking basics Network types Protocols Glossary theNET ...
Learn about the first layer of the OSI model, the physical layer. This definition covers what it is, its functions, associated protocols and topologies.
Network Layer Physical Layer Application Layer The application layer is a combination of the application, presentation, and session layers. This layer is responsible for interaction between the user and the application. Here, data is formatted, converted, encrypted, decrypted, and set to the user. ...
