授業の到達目標及びテーマ
Students are expected to understand basic communication technologies, important LANs and WANs, network models and the key Internet protocols.
授業の概要と方法
The course attempts to provide a unified overview of the broad field of data communications and computer networks as well as the Internet. It is divided into two parts. Part I, data communication and networks, is concerned primarily with transmission media, communication models, data transfer, modulation, coding, link control, multiplexing, and switch. Network architecture and topologies, layered OSI model, local area network (LAN), wide area network (WAN), and mobile network, are also discussed in this part. Part II is focused on the Internet technologies, its architecture, addressing schemes, and important communication protocols such as IPv4, IPv6, ARP, ICMP, UDP, TCP, RTP, SNMP, etc.
