Andrew S. Tanenbaum’s Computer Networks lecture materials provide a comprehensive, bottom-up examination of network architecture, covering protocols from the physical layer to application-level interfaces. The curriculum focuses on a layered approach (OSI/TCP/IP models) to dissect crucial topics including data link channel allocation, routing algorithms, and congestion control. Various versions of the slides are available online, such as those on SlideShare or hosted by institutions like National Taiwan University.

Layer 2: The Data Link Layer (Reliable Frames)

Slide Focus: Error detection, flow control, and Medium Access Control (MAC).

This is where the slides earn their keep. Topics like Hamming codes and Cyclic Redundancy Check (CRC) are notoriously math-heavy. A good Tanenbaum slide will show a simple example of a corrupted frame and step through the XOR process. Firewalls: Packet filter (IP/Port)

A classic slide sequence here covers:

• The Sliding Window Protocol (stop-and-wait vs. go-back-n). Animated slides show the sender’s window shrinking and expanding over time.
• The Ethernet MAC sublayer and the binary exponential backoff algorithm after a collision.
• Bridges and switches learning MAC addresses (a table-based animation).

2. The "Cabling" Problem

Historically, Tanenbaum's materials spend a significant amount of time on the Physical Layer—specifically cabling types (Cat-5, fiber optics, coaxial) and modulation techniques.

• Critique: In a modern context, this often feels dated. While the physics of transmission are timeless, modern students often want to skip straight to software-defined networking or cloud infrastructure, which receive less attention in the standard slide decks.

Chapter 8: Network Security

• Symmetric Key (AES, DES): Same key for encrypt/decrypt. Fast. Problem: Key distribution.
• Asymmetric Key (RSA): Public/Private key pair. Slow. Used for digital signatures and key exchange.
• Hashes (SHA-256): One-way function. Used for integrity (MAC).
• TLS/SSL (Transport Layer Security):
  1. Handshake: Negotiate cipher, verify cert (RSA/ECDHE).
  2. Exchange symmetric session key (AES).
  3. Encrypted data flow.
• Firewalls: Packet filter (IP/Port), Stateful (tracks connections), Application (Deep Packet Inspection - DPI).
• Attacks: DDoS (SYN flood), Man-in-the-Middle (ARP poisoning), DNS Spoofing.
