Introduction to TCP/IP: This module introduces the TCP/IP model, its history, and the importance of this protocol suite in modern networking. You will learn about the evolution of networking and how TCP/IP became the standard for global communication.

Layers of the TCP/IP Model: In this module, you will delve into the four layers of the TCP/IP model: the Application Layer, the Transport Layer, the Network Layer, and the Link Layer. You will understand the functions and protocols associated with each layer and how they interact to facilitate seamless data transmission.

Internet Protocol (IP): This module focuses on the Internet Protocol, a fundamental component of the TCP/IP model. You will learn about IP addressing, IP version differences, subnetting, and routing. By the end of this module, you will be able to configure IP addresses and understand IP packet forwarding.

Transmission Control Protocol (TCP): In this module, you will explore TCP, a connection-oriented protocol that ensures reliable data transfer. You will learn about TCP segment structure, three-way handshake, data acknowledgment, and windowing. This knowledge will enable you to understand and implement TCP in various networking scenarios.

User Datagram Protocol (UDP): This module introduces UDP, a connectionless protocol that offers faster data transfer at the cost of reliability. You will learn about UDP segment structure, port numbers, and the differences between TCP and UDP. This knowledge will help you decide when to use UDP over TCP.

Transport Layer Security (TLS) and Secure Sockets Layer (SSL): In this module, you will learn about the security protocols TLS and SSL, which are used to secure data transmission over the internet. You will understand the principles of encryption, key exchange, and certificate authorities, and learn how to implement secure connections in your applications.

Application Layer Protocols: This module covers various application layer protocols, such as Hypertext Transfer Protocol (HTTP), File Transfer Protocol (FTP), Simple Mail Transfer Protocol (SMTP), and Domain Name System (DNS). You will understand the functioning and purpose of each protocol and their role in modern networking.

Network Security: In this module, you will learn about network security threats, such as attacks on the application, transport, and network layers. You will also study security measures like firewalls, intrusion detection systems, and virtual private networks (VPNs) to protect networks and data.

Practical Implementation and Troubleshooting: This module focuses on hands-on experience with TCP/IP networking. You will learn to configure and manage network devices, such as routers and switches, and troubleshoot common networking issues. This practical knowledge will help you apply your learning to real-world scenarios.

Course Conclusion and Future Directions: In the final module, you will review the key concepts covered in the course and explore future directions in networking, such as software-defined networking (SDN), network function virtualization (NFV), and the Internet of Things (IoT).
