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 t
In this article, we will talk about the much-asked query of what is layer 2 network is and how its w
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...
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...
When looking at the physical layer of a computer network, there are two primary types: Wired networkingrequires the use of a physical medium for transport between nodes. Copper-based Ethernet cabling, popular due to its low cost and durability, is commonly used for digital communications in busin...
IPsec is a group of networking protocols used for setting up secure encrypted connections, such as VPNs, across publicly shared networks. Learning Center Network layer How Internet works Networking basics Network types Protocols Glossary theNET ...
Network security is the practice of protecting computer networks against unauthorized access, misuse or destruction by malicious actors such as hackers or malware. This can include installing firewalls, setting up secure passwords on all accounts, using two-factor authentication whenever possible & monitor...
Description and Functions of Network Layer in the OSI model: In this tutorial, we are going to learn what the Network layer is and the Functions of Network Layer in the OSI model in Computer Networking. we will also discuss the Design Issues with Network
Computer Networks fall into three classes regarding the size, distance and the structure namely: LAN (Local Area Network), MAN (Metropolitan Area Network), WAN (Wide Area Network). Before we discussing about type of network we can discuss about what is a
Consequently, “switching” refers to how data is transferred between devices on a network. Networks rely on three main types of switching: Circuit switchingestablishes a dedicated data communication path between nodes in a network, so no other traffic can traverse the same path. Circuit switching ...
