Computer Networks
This course dissects the complete networking stack, analyzing principles from physical transmission media to complex application protocols. It covers the core mechanics of switching, multiplexing, and LAN topologies, alongside a rigorous examination of IP addressing and routing strategies. You will evaluate the reliability trade-offs between TCP and UDP, understanding their critical role in supporting modern services like HTTP and VoIP.
Chapters
Foundations of Computer Networks
Explore the complete lifecycle of data transmission, moving from network topologies to the logical layers of the OSI model. This module covers the mechanics of switching and multiplexing, while examining how window protocols manage flow control. You will gain a practical understanding of how these fundamentals support robust service models.
Transmission Media and Data Encoding
This section details the operation of the Physical Layer, focusing on bit encoding strategies and media characteristics. You will learn to evaluate how different transport technologies influence speed.
Data Link Layer and Local Area Networks
Master the mechanics of local connectivity. This module covers the Data Link Layer responsibilities before diving into practical LAN architectures. It compares wired (Ethernet) vs. wireless (WiFi) standards and defines the function of key network devices in segmenting and extending networks.
Network Layer and Routing
This module dissects the Network Layer, the engine of global connectivity. You will master addressing architectures using IPv4 and DHCP, and analyze how Routing Algorithms determine optimal data paths across the Internet. It also covers essential control protocols like ICMP and ARP, alongside NAT strategies for address conservation.
Transport and Application Layers
Master the upper layers of the network stack. This module distinguishes between connection-oriented (TCP) and connectionless (UDP) transport strategies. You will apply these concepts to standard Application Layer protocols, covering the complete lifecycle of web traffic (HTTP), electronic mail, P2P file sharing, and real-time VoIP transmission.
