AP COMPUTER SCIENCE PRINCIPLES
UNIT 2
IP - ANSWER Internet Protocol for data and information transmission between
devices.
The Internet - Answer A global network system made up of interconnected
computers and devices.
End-to-End Architecture: ANSWER A design principle for network
configurations. The principle asserts that, if practical, communications protocol
activities should be established to take place at the endpoints of a
communications system, or as close as practicable to the resource under control.
Device - ANSWER A machine that has a defined purpose or function and can
communicate with other devices.
Network - ANSWER A collection of computer systems connected via
communication systems.
DNS stands for ANSWER Domain Name System. Retrieves IP addresses based
on the request. Converts alphabetical names to IP addresses.
Browser - Answer A software program that allows users to access the Internet.
Web server - ANSWER A computer that awaits and responds to requests for
data.
IPv4 vs. IPv6: ANSWER IPv4 can hold 2^32 IP addresses, while IPv6 can hold
2^128. Switching to IPv6 is important because of the increased demand for IP
addresses.
HTTP/HTTPS: ANSWER The protocol used on the World Wide Web. It covers
the format and interchange of messages, as well as how web servers respond to
commands. Computers communicate using a particular language. HTTPS is a
