1. DNS:

This session explores the Domain Name System (DNS), which translates domain names into IP addresses. We will cover DNS hierarchy, resolution processes, and caching mechanisms, highlighting DNS’s critical role in internet functionality and addressing common issues.

1. HTTP:

This session examines the Hypertext Transfer Protocol (HTTP), the cornerstone of web communication. We will discuss the request-response model, HTTP methods, and the evolution of HTTP versions, focusing on their performance improvements and security features essential for modern web development.

1. Ethernet:

This session delves into Ethernet technology, the backbone of local area networks (LANs). We’ll cover the fundamentals of Ethernet, including its history, standards (such as IEEE 802.3), and how it enables devices to communicate over a network. Understand the mechanics of Ethernet frames, MAC addresses, and the role of switches and hubs in managing data traffic within a LAN, ensuring fast and reliable connectivity.

2. User Datagram Protocol (UDP):

This session focuses on the User Datagram Protocol (UDP), a key component of the Internet Protocol suite. Discover the characteristics of UDP, including its connectionless nature and minimal protocol mechanism, which provide low-latency transmission ideal for real-time applications. We’ll examine how UDP differs from TCP, its structure, use cases like video streaming and online gaming, and the trade-offs involved in choosing UDP for data communication.

1. Packets and Protocols:

This session covers the basics of packets and protocols in networking. Learn how data is split into packets for transmission and the role of protocols like TCP/IP, UDP, and HTTP in ensuring data integrity and communication efficiency.

2. The Internet Protocol (IP)

This session focuses on the Internet Protocol (IP), which routes data packets using IP addresses. We’ll discuss IP packet structure, IP addressing, and the differences between IPv4 and IPv6, along with an overview of IP routing.

1. Global IP Routing:

This session covers the basics of global IP routing, explaining how data is directed across the world’s interconnected networks. We’ll discuss routing tables and the processes involved in ensuring efficient and reliable data delivery on a global scale.

2. Unicast, Multicast, Anycast:

This session explores different types of IP communication: unicast, multicast, and anycast. Learn the distinctions between these methods, including one-to-one communication (unicast), one-to-many distribution (multicast), and sending data to the nearest node in a group (anycast), along with their applications and benefits.
