TCP/IP Model - GeeksforGeeks
It stands for Transmission Control Protocol/Internet Protocol. The TCP/IP model is a concise version of the OSI model. It contains four layers unlike the seven layers in the OSI model. The number of layers is sometimes referred to as five or four. Here In this article we’ll study five layers.

The data link layer provides error-free transfer of data frames from one node to another over the physical layer allowing layers above it to assume virtually error-free transmission over the link. The network layer controls the operation of the subnet deciding which physical path the data should take based on network conditions priority of service and other factors. The transport layer ensures that messages are delivered error-free in sequence and with no losses or duplications.
TCP/IP Model vs. OSI Model | Similarities and Differences ...
The biggest difference between the two models is that the OSI model segments multiple functions that the TCP/IP model groups into single layers. This is true of both the application and network access layers of the TCP/IP model which contain multiple layers outlined within the OSI model.

There‣s a lot of technology in Layer 1 - everything from physical network devices cabling to how the cables hook up to the devices.

Layer 2 defines how data is formatted for transmission how much data can flow between nodes for how long and what to do when errors are detected in this flow. In more official tech terms 1. Line discipline.Who should talk for how long? How long should nodes be able to transit information for? 2. Flow control.How ... See full list on freecodecamp.org Layer 3 is the network layer. This is where we send information between and acrossnetworks through the use of routers. Instead of just node-to-node communication we can now do network-to-network communication. Routers are the workhorse of Layer 3 - we couldn‣t have Layer 3 without them. They move data packets across multiple networks. Not only do ...

This where we dive into the nitty gritty specifics of the connection between two nodes and how information is transmitted between them. It builds on the functions of Layer 2 - line discipline flow control and error control. This layer is also responsible for data packet segmentation or how data packets are broken ...
