Description of What Is TCP IP Model? Training
This course provides a clear introduction to the TCP/IP model and protocols that power modern network communication. You’ll learn how data packets move through the layers of the protocol suite and how Transmission Control Protocol and User Datagram Protocol differ in their approach to moving information.
Through concise explanations, you’ll see how the network access layer handles the data link and physical connections that enable communication between devices. You’ll also review how addressing schemes and protocol layers work together to support reliable data transmission.
By the end of this course, you will:
- Grasp the core functions of each TCP/IP layer
- Identify key differences between the TCP/IP and OSI models
- Understand the old vs. new TCP/IP models required for Cisco exams
- Recognize major protocols within the suite and their functions
- Build confidence in applying these concepts to real-world networking
Mastering TCP/IP is a crucial step toward strengthening your knowledge in networking, cybersecurity, and systems administration.
Who Is This Course For
This course is perfect for IT professionals seeking deeper knowledge of TCP/IP, students studying computer networks, and anyone preparing for certifications that require understanding of core networking protocols and concepts.

Testimonials
Nicholas R.
I’m only a third of the way through this course, but I have to say how much I appreciate the way Lazaro explains everything about TCP/IP, the do’s and don’ts, and how clearly he covers topics like the network interface layer, data packets, and the application layer.
Update: I’ve completed the course now, and it was fantastic—extremely informative, well organized, and packed with insights into protocols like file transfer protocol and internet control message protocol.
Gerardo T.
Instructor is energetic and takes his time to explain concepts with real-life examples. Good introductory material that shows how to transfer data securely over different network media, use tcp protocol, and understand network applications and security protocols to encrypt data across any network channel.
Nicholas P.
Laz is always an amazing instructor. Easy to listen to, with good pacing and communication skills. He makes the information easy to digest and not boring, especially when covering communication protocols, error detection, the seven layers of networking, and how the domain name system and routing data work in real scenarios.
