Computer Networks
Subject Overview
Computer Networks covers network architecture and reference models (OSI, TCP/IP), the medium access sublayer and networking devices, high-speed LANs and routing/congestion control algorithms, and internet protocols and network security including encryption, digital signatures and distributed applications. A 4-credit core theory paper.
