We will explore the fundamental concepts of Artificial Intelligence (AI), including its definition, intelligence, and key foundational areas. We will examine different approaches to AI, such as the Rationalist and Empiricist perspectives, and understand their applications and limitations. Additionally, we will delve into the concept of intelligent agents, their interaction with environments, rational decision-making, and the various structures that define their behavior in different settings.

We will learn how the Link Layer enables direct communication between devices by managing framing, error detection, and medium access control. You’ll explore multiple access protocols, Ethernet, ARP, VLANs, and how switches improve network performance. The module also covers wireless networks, including WiFi, CDMA, and Mobile IP, ensuring seamless connectivity in wired and wireless environments.

The Network Layer is responsible for routing, addressing, and forwarding data across different networks, ensuring seamless communication. It manages logical addressing through IP, supports packet forwarding via routers, and utilizes routing algorithms like Dijkstra’s and Bellman-Ford to determine optimal paths. The layer operates using service models such as virtual circuit and datagram networks, balancing reliability and efficiency. Concepts like IPv4, IPv6, ICMP, and IPSec enhance security and scalability. Understanding the network layer, routing algorithms, and hierarchical structures is crucial for optimizing network performance and maintaining connectivity across complex systems.

we explore the Transport Layer, which is essential for managing communication between applications across networks. We learn how it provides services like reliability, error detection, and congestion control through protocols like TCP and UDP. TCP ensures reliable, ordered delivery using acknowledgments, retransmissions, and congestion control mechanisms, making it ideal for applications like web browsing and file transfers. UDP, on the other hand, offers fast, connectionless communication with minimal overhead, suitable for real-time applications like gaming and streaming. We also examine multiplexing and demultiplexing, which allow multiple applications to use the network simultaneously. Finally, we dive into congestion control strategies that help maintain network efficiency and stability, ensuring smooth data transmission even under heavy traffic conditions.

we learn how network applications communicate using Client-Server and P2P models, the role of TCP and UDP in data transmission, and the workings of HTTP, including requests, cookies, and caching. You’ll also learn how DNS translates domain names to IPs and explore socket programming with UDP for building network applications.

The Internet and computer networks form the backbone of modern communication, enabling data transfer, online services, and global connectivity. This blog explores the fundamental concepts of computer networks, covering the Internet, network structure, protocols, security, and history.
