Computer Networks

• Network Foundations

  How computer networks are organized at a high level, from layering and encapsulation to the basic technologies that move data between hosts.

• Transport and Reliability

  How endpoints establish transport sessions, recover from loss, and balance delivery guarantees against latency.

• Internet Addressing and Routing

  How the internet layer identifies hosts, resolves next-hop delivery, and chooses paths across networks.

• Network Protocols

  How applications use protocols such as DNS, HTTP, TLS, and newer HTTP versions to find services and exchange meaning over the network.
