Course Introduction
Course description:
• Introduction to computer networks and the Internet: Protocol layers and the OSI
model. Physical layer: Data and Signals, Nyquist Bit Rate and Shannon Capacity. Data
Link Layer: error detection and correction, multiple access, MAC addressing,
switches, ARP, MAC Frame (IEEE 802.3 protocol), Wired LAN Ethernet, Virtual Circuit,
and WLAN (IEEE 802.11 protocol). Transport layer: UDP, TCP and congestion control.
Network layer: virtual circuits, routers, IP protocols and routing algorithms.
Application layer: HTTP, FTP, SMTP, POP3, DNS and peer-to-peer applications.
