Exam Coverage
Exam coverage for CS6250 Computer Networks Exam 1 includes
foundational computer networking concepts typically covered in the
first portion of a graduate-level networks course. It focuses on
network architecture and layered models, packet switching, circuit
switching, delays and throughput, the Internet structure, and core
protocols at the application, transport, and network layers. The exam
also evaluates understanding of IP addressing, subnetting, DNS, HTTP,
TCP, UDP, routing basics, and performance concepts such as latency,
congestion, and reliability. Emphasis is placed on understanding how
data moves across networks, analyzing protocol behavior, and
applying networking principles to real-world communication systems.
