Computer Networks

Course Purpose
The purpose of this course is for students to understand protocol hierarchy, which is a foundation of designing and constructing information networks, and to learn how information is transferred and processed through information networks.
Learning Goals
Students will be able to understand the following basic technologies of Internet: a) IP addressing, b) access control, c) error detection and correction, d) routing, e) IP datagram, f) window control, g) flow and congestion control, h) internet applications ( WWW, e-mail, DNS), i) network programming, j) network security, k) multimedia networks.
Topic
