Computer Network | Layer 2 Switching: In this tutorial, we will learn about the layer 2 switching, functions of layer 2 switching in computer network.
Learn about the OSI Layer 3. The Network Layer. is where actual low level networking takes place, usually trough IPv4/v6. Including all the relevant Network layer protocols
basics of computer networking. It is very worth keeping in mind that the real-world implementation of protocols differs somewhat. There are plenty of layer-crossing protocols. Modern networking concepts don’t necessarily fit into the OSI model well. Still, it is helpful to understand the basics...
Internet layer: This layer is responsible for exchanging datagrams. A datagram contains the data from the transport layer and adds in the origin and recipient IP addresses. The protocols associated with this layer are IP, ICMP, and the Internet Protocol Security (IPsec) suite. Network access lay...
IPsec (Internet Protocol Security): IPsec provides a suite of protocols for securing IP communication. It provides strong encryption and authentication and is usable in both remote access and site-to-site VPN configurations. SSL/TLS (Secure Sockets Layer/Transport Layer Security): SSL and its succe...
The five layers of the TCP/IP network are generally introduced and then each layer is studied in a separate section. The layer is defined, then its function is explained and the important protocols and processes are explained. An example of the protocols and processes is given when it is ...
network operations. The third layer – the network layer – is crucial to transferring data packets between different networks. In this article, we’ll cover what the network layer is and its functions, the network layer protocols, and the issues one may encounter at the third layer. ...
