ARPANET One of the first operational packet-switching
networks and the precursor to the modern Internet
developed by an agency of the United States
Department of Defense.
It became operational in 1969.
It used packet-switching technology to transmit data
between computers and played a crucial role in the
development of networking protocols such as
TCP/IP.
(Advanced Research Projects Agency Network)
SMTP A standard protocol (used on port 25) for sending
and receiving email messages over the internet;
messages are sent from a sender's email client or
server to the recipient's email server.
Operates as a text-based protocol, meaning that
communication between email servers occurs
through plain text commands and responses.
Contains mechanisms for error detection,
acknowledgement, authentication, and
retransmission in case of failures during the transfer
process.
(Simple Mail Transfer Protocol)
IP address A computer's address and unique identifier (like an
building's street, state, zip)
Port A computer's "mailbox or apartment" #
Has a range of 0 - 64,000
,URL The human readable version of an IP address
Server The system that provides the
functionality/model/data for a client trying to do
some work/play.
Client The individual/system attempting to do work/play on
a server.
Where the GUI is usually displayed.
DNS Translates human readable domain names into IP
addresses that computers use to identify each other
on a network.
(Domain Name System)
Category The first set of digits in an IP address representing
high level grouping like .com or .edu
Identifier The second set of digits in an IP address representing
division within the category (utah, google, amazon)
Subnet The third set of digits in an IP address representing
subdivisions of the identifier (UofU has subnets CS,
ECE, etc.)
Machine The fourth set of digits in an IP address representing
the individual ____________.
Client needs 1. The address of the server machine
2. Initial port to talk to
3. A unique port for future communication
(continuing port)
4. The protocol(s)
Initial port The specific low port used by a server supporting a
query/response program.
Allows anyone to make an initial connection that is
later moved to another port so new clients can talk
to the server.
, Continuing port A higher port number that clients are moved to after
connecting to an initial port of a server supporting a
query/response program.
Allows new clients to talk to the same server at the
same time.
Socket An identifier representing a particular point to point
communication connection between two pieces of
software.
My IP address, their IP address, my port #, and their
port # are combined into a single unique
communication channel
Protocols Agreed order and format of data for communication
IP The protocol responsible for sending packets of
information from host to host.
(Internet Protocol)
TCP A protocol ran on top of IP that provides one to one
reliable communication that ensures:
data will arrive, ordering, no corruption.
It does not, however, verify when data arrives or how
much arrives at a given time
(Transmission Control Protocol)
UDP An alternative to TCP that does not have a persistent
connection and does not ensure delivery, ordering,
or duplication protection.
This protocol simply broadcasts information.
