Internet Engineering Task Force
a computer network
that uses open protocols to standardize communication.
computing system that is capable of sending or receiving data.
a group of computing
devices and programs working together for a common purpose.
a physical object that
can run a program, such as computers, tablets, cell phones, and smart sensors.
World Wide Web
a system of linked
pages, programs, and files that uses the Internet.
a computer that passes
information from one network to another.
ISPs (Internet Service
the companies who sell
Internet access to homes and institutions.
a sequence of directly
connected computing devices that connect a sender to a receiver.
the process of finding
a path from sender to receiver.
the ability of the
Internet to keep working as it grows.
the inclusion of
back-up elements in case one part fails.
the ability of a
system to work around problems.
a set of rules that
specify the behavior of a system.
a unique number
assigned to each device on a computer network.
is a small chunk of
any kind of data (text, numbers, lists, etc.) and metadata (information about
the data) that is passed through the Internet as a data stream.
The way the Internet
sends short bursts of information, not long continuous strings is called ____
the protocol that your
browser uses to access an HTML web page
the protocol that
assures reliable transmission of data. lets your computer pretend it has a
reliable connection to the other computer
IP (Internet Protocol)
lets your computer
pretend it has a direct connection to another computer
Protocols (such as HTTP)
the highest level of
abstraction, manage how data is interpreted and displayed to users.
Protocols (such as TCP)
manage the breakdown
of a message into packets to be transmitted by lower level protocols and also
the reconstruction of the message from the packets upon arrival.
Protocols (such as IP)
manage the pathways
that the data packets travel across networks.
Hardware (using Link Layer Protocols such as WiFi)
manage the connection
between an Internet device and its local network. These local protocols are the
least abstract because they deal directly with your physical hardware.
standards not owned by
a company such as HTTP, SMTP, TCP/IP
Task Force (IETF)
develops and promotes
voluntary Internet standards and protocols, in particular the standards that
comprise the Internet protocol suite (TCP/IP).
the maximum amount of
data that can be sent in a fixed amount of time (for digital data, it is
measured in bits per second).
storing data somewhere
on the Internet, but you don't know where. (Google, Dropbox, Amazon, Snap!,
