AP Computer Science Principles Unit 2 Questions and Answers
IP - -Internet Protocol for how data and information online mail transmission
is sent between devices
IETF - -Internet Engineering Task Force. Develops
The Internet - -A global network system composed and promotes voluntary internet standards and protocols,
of computers and devices that are all connected to each in particular, the standards that comprise the internet
other protocol suite
End-to-End Architecture - -A design principle in Allows for scalability - -Hierarchy
setting up a network. The principle states that, whenever
possible, communications protocol operations should be
defined to occur at the end-points of a communications Redundancy - -Fault tolerance. The mechanism of
system, or as close as possible to the resource being extra components that are not necessary to functioning, in
controlled. case of failure of components
Devices - -A machine that has a specific purpose or Routing - -The process of moving data from the
function, capable of communicating with other devices sender to the receiver
Network - -A group of computer systems that are all Scalability - -The capability of a system, network, or
linked through communication systems process to handle a growing amount of work
DNS - -Domain Name System. Retrieves IP Protocol - -The set of rules governing the exchange
addresses per request. Converts alphabetical names into of data between devices.
IP addresses
Interface - -Allows the user to communicate and use
Browser - -A software program that people use to the computer or program
access the Internet
Packet switching - -Breaking large pieces of
Web server - -A computer that awaits and responds information down into packets.
to requests for data
TCP/IP - -Transmission Control Protocol- provides
IPv4 vs. IPv6 - -IPv4 can contain 2^32 IP addresses reliable, ordered, and error-checked delivery of a stream
while IPv6 can contain 2^128. Switch to IPv6 is necessary of packets on the Internet. Tightly linked with IP.
because of the growing demand of IP addresses
SSL/TLS - -Secure Sockets Layer, the standard
HTTP/HTTPS - -The protocol used by the World technology for keeping an internet connection secure and
Wide Web. It describes how messages are formatted and safeguarding any sensitive data that is being sent between
interchanged, and how web serves respond to two systems. TLS (Transport Layer Security) is just an
commands. The language computers use to updated, more secure, version of SSL. Makes sure device
communicate. HTTPS is a communications protocol for is secured, padlock icon
secure communication over a computer network which is
widely used on the Internet. (S stands for secure)
Bandwidth - -Transmission capacity measured by bit
rate. High bandwidth= good
SMTP - -Simple Mail Transfer Protocol. Protocol for
1/2
