About This Course

Welcome to Computer Networks & Web Protocols, an online video course designed to demystify the complex world of the Internet. Built around the world-renowned textbook, Computer Networking: A Top-Down Approach (8th Edition) by Kurose and Ross, this course takes a unique "top-down" pedagogical approach. Instead of starting with the physical hardware and working upwards, we begin at the Application Layer—the part of the network you interact with daily. By understanding how web browsers, video streaming, and email work first, you will gain immediate, intuitive motivation to explore the underlying layers that support them. We will journey down the protocol stack through the transport, network, and link layers, concluding with modern wireless networks and network security.

 

What You Will Learn

Through engaging video lectures and hands-on concepts, you will master:

  • Application Layer Principles: How modern applications communicate using HTTP, DNS, SMTP, and video streaming protocols.
  • Transport Layer Protocols: The mechanics of reliable data transfer, flow control, congestion control, and the details of TCP, UDP, and the newer QUIC protocol.
  • Network Layer Operations: The distinction between the data plane (IP addressing, IPv4/IPv6, and forwarding) and the control plane (routing algorithms, OSPF, BGP, and Software-Defined Networking).
  • Link Layer & LANs: Ethernet, multiple access protocols (CSMA/CD, CSMA/CA), switched local area networks, and the architecture of massive modern Data Centers.
  • Wireless & Mobile Networks: The characteristics of wireless links, 802.11 (WiFi), 4G/5G cellular systems, and mobility management.
  • Network Security: Cryptographic fundamentals, message integrity, digital signatures, and secure protocols like TLS and IPsec.

 

Why Take This Course?

Computer networking is the backbone of the digital age. This course provides a highly structured and comprehensive curriculum aligned with top-tier academic standards and BCS exam guidelines. By starting "top-down," you will appreciate the why behind every technical design decision. Rather than memorizing dry standards, you will build a principled framework to understand both today's internet and tomorrow's emerging technologies, such as Cloud Computing and Software-Defined Networks.

 

Who Should Take This Course?

This course is specifically crafted for:

  • Students preparing for BCS (British Computer Society) certifications or university-level networking exams.
  • Aspiring Software Engineers and Systems Administrators who want to understand "under the hood" network behaviors.
  • Technology professionals seeking to solidify their foundational knowledge of web protocols and secure architectures.

 

What will I learn?

  • Ace Professional Examinations: Confidently sit for university-level networking exams and professional certifications such as the BCS networking modules.
  • Build Real-World Network Apps: Showcase a portfolio featuring custom-coded Python TCP/UDP sockets and a custom-built Web server.
  • Troubleshoot Network Performance: Professionally diagnose latency bottlenecks, packet loss, TCP congestion states, and routing anomalies.
  • Design Secure Architectures: Evaluate and implement standard network security controls including SSL/TLS, firewalls, VPNs, and Intrusion Detection Systems.

Verifiable Credentials

Every single course certificate issued by Atlanta College of Liberal Arts and Sciences (ACLAS) is verifiable via our digital registry and is eligible for institutional authentication (Apostille/IECC), ensuring your professional milestones are recognized globally as of 2026.

Curriculum

Requirements

  • Basic Programming Skills: Familiarity with Python programming fundamentals (variables, loops, functions, and exceptions) is highly recommended for the socket programming module.
  • Elementary Math & Algebra: Comfort with basic algebra is necessary for calculating network delays, queueing intensities, subnets, and cryptographic algorithms.
  • General Computer Literacy: Ability to operate a command-line interface (CLI) to run scripts and install Wireshark on your local machine (Windows, macOS, or Linux).
