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 ...
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 ...
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 networ
level. This also ensures that a fast host on a network doesn't overtake a slower one. Essentially, the transport layer ensures that the entire message is delivered from beginning to end. It also confirms a successful data transmission and retransmitting of the data if an error is discovered....
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. ...
The logical addressing at the network layer while physical addressing at the data link layer is defined by the MAC address of a device, whereas the IP addressing is determined at the network layer of the OSI model. This addressing is also called as logical addressing. ...
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...
