CS6250 Computer Networks Exam 1
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.
,What is the Domain Name System (DNS) designed to do primarily?
Translate domain names into IP addresses
How did Licklider and his team in the early 1960s experiment with a
precursor to the Internet?
Connecting two computers over a dial up telephone line
What is the architectural design of the Internet protocol stack based
on?
Layers
,Both the data link and transports layer protocols may provide error
correction
True
What allows for communication between the application layer and the
transport layer?
Sockets
, Which of the following protocols belong to the application layer?
Ethernet
IP (Internet Protocol)
DNS (Domain Name Service)
UDP (User Datagram Protocol)
DNS (Domain Name Service)
