3. Network layer: Handles the routing and sending of data between different networks. The most important protocols at this layer are IP and ICMP. 2. Data link layer: Handles communications between devices on the same network. If layer 3 is like the address on a piece of mail, then layer...

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 network layer performs two types of services for the transmission of packets. They are virtual circuit and datagram services. A virtual circuit is a connection-oriented service and datagram is a connectionless service. In the connection-oriented approach, a complete path is formed bet...
What is a layer 3 switch? In today's intricate enterprise networks that consist of numerous subnets and virtual LANs, the presence of a layer 3 switch holds significant importance. However, is a layer 3 switch necessary for your network? Let's delve into this matter. Introduction: To put ...
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 ...
In the Open Systems Interconnection (OSI) model, logical network diagrams correlate with the information contained in layer 3 (L3). Also known as the “network layer,” L3 is an abstraction layer that deals with packet forwarding through intermediate routers. Level 2 shows the data links between...
A network, in computing, is a group of two or more devices or nodes that can communicate. The devices or nodes in question can be connected by physical or wireless connections. The key is that there are at least two separate components, and they are connected. ...
transport- layer segment: generated by the transport layer and encapsulates application- layer message with transport layer header; network- layer datagram: encapsulates transport- layer segment with a network- layer header; link-layer frame: encapsulates network-layer datagram with a link-layer header...
Nodes highly depend on the referred network and protocol layer to form a network connection. Additionally, each node on a network includes a unique IP address. Nodes in a threaded environment can be divided into two roles: Routers: The role of a router node is to transmit packets from ...
