Difference to TCP model and OSI model?
What exactly is the difference between the models?
One is simply shorter, but why are there both? Do they both serve the same function?

Should I continue streaming on Twitch or start streaming on Kick?
ByNamitus
Good morning You've probably noticed what's going on with Twitch and I've been wondering if I should just continue with kick or start or wait and see what you would do.
Where does all my RAM go?
I have 16GB of RAM. That's how it's shown to me. It just doesn't seem to specify where the RAM goes. Without a game open, I easily use 11GB of RAM. What's eating up my RAM?
Is there a way to receive email notifications faster on my phone?
The question is already above. My problem is that I usually receive notifications on my phone many minutes or even hours later, and not always immediately seconds after the email arrives. Is there a way to get them faster?
Will it be the case in the future that you will have to verify your ID and phone number for each account you create?
Hello. So I wanted to ask if there will be a new worldwide legal regulation in the future that requires you to verify a telephone number and ID card for every account you create on any website (regardless of whether it is online games etc.) so that you can better protect yourself against misuse and…
PC keeps restarting after CPU upgrade?
After about 40 minutes, the PC always restarts. It doesn't turn off, it just restarts. I bought the CPU from a friend Ryzen 7 5700g.The processor was also in good condition with the pins
Does anyone know of a laptop for €400 where you can play City Car Driving (Steam) or Beamng Drive?
Who knows laptops where you can play City Car driving(Steam) or beamng drive on it? Laptop must not cost more than 400 €
Hier findet du eine Erklärung beider Modelle. Beide Modelle standadisieren, wie Hard- und Softwarekomponenten zusammenarbeiten müssen, damit eine Netzwerkkommunikation erfolgen kann. Das OSI-Modell ist dabei in 7 Schichten (Layer) unterteilt, das TCP/IP-Modell begnügt sich mit 4 Beschreibungs-Schichten.

The two models differ in that the OSI model is more finely structured:
While the TCP/IP model combines several layers of the OSI model, only IP and TCP face each other there.
The TCP/IP model is older than the OSI model, here it is perhaps explained better than I could:

Imagine you're writing a letter to a friend and want to mail it. Before you do, you have to put the letter in an envelope, write the address on it, and then drop the envelope in the mailbox. This is a kind of "model" for how you'll get the letter from one place to another.
The TCP model and the OSI model are similar to the letter example. They show how data travels from one computer to another. Both models have different layers, or stages, that describe the different parts of the transmission. The OSI model has seven layers, while the TCP model has only four.
While there are differences between the two models, they both serve the same purpose: to help understand how data is exchanged between computers. The choice of which model to use often depends on the specific situation, but in general, the OSI model is somewhat more detailed and is more commonly used in larger networks.
But the TCP model uses the layers from the OSI model, so they actually do the same thing and have the same use cases, right?
Both models have their own advantages and use cases, depending on the type of network you have. But overall, you can say they share the same goal: ensuring data is transferred securely and reliably from one computer to another.
The OSI model is the more general model that can also be applied to non-IP-based networks.
Hello!
The Transmission Control Protocol (TCP) model and the Open Systems Interconnection (OSI) model are both network protocol reference models. They define the functions a network protocol should fulfill to enable successful communication between different devices.
The main difference between the two models is that the OSI model consists of seven layers, while the TCP model consists of only four. The OSI model is a theoretical and conceptual representation, while the TCP model is more based on practical applications.
The OSI model divides network functions into seven layers, which are passed through sequentially to enable successful communication. Each layer has a specific function and works with other layers to ensure seamless communication. The seven layers are: application layer, presentation layer, session layer, transport layer, network layer, data link layer, and physical layer.
The TCP model, on the other hand, divides network functions into four layers: the application layer, the transport or host-to-host layer, the internet or network layer, and the network access layer. The application layer contains protocols required for communication between applications on different devices. The transport or host-to-host layer ensures that data can be exchanged between devices. The internet or network layer is responsible for transferring data between different networks. The network access layer includes protocols and hardware required to access a physical network.
Both models essentially serve the same function: they provide a framework for developing network protocols and applications. However, the OSI model is more of a theoretical model, while the TCP model is a practical model developed based on experience in the field of network communications.
I hope this helps you!
