Comp. Flashcards
a machine that can run a program, including
computers, tablets, servers, routers, and smart sensors
Computing Device
a
group of interconnected
computing devices
capable of sending or
receiving data.
Computing Network
the series of
connections between
computing devices on
a network starting with
a sender and ending
with a receiver.
Path
the maximum amount of data that can be sent in a fixed
amount of time, usually measured in bits per second.
Bandwidth
a group of computing devices and programs
working together for a common purpose
Computing System
An agreed-upon set of rules that specify the
behavior of some system
Protocol
a protocol for sending data
across the Internet that assigns unique numbers (IP
addresses) to each connected device
Internet Protocol (IP)
The unique number assigned to each
device on the Internet.
IP Address
the inclusion of extra components so that a system
can continue to work even if individual components fail, for
example by having more than one path between any two
connected devices in a network.
Redundancy
Can continue to function even in the event of
individual component failures. This is important because elements
of complex systems like a computer network fail at unexpected
times, often in groups.
Fault Tolerant
A type of computer that forwards data across a network
Router
2 protocols commonly used to send packets online
User Data Protocol (UDP) - Sends packets as fast as possible
Transmission Control Protocol (TCP) - Number packets so they can be
re-ordered, confirm all were received, resend any missing packets.
Information
passed through the
internet in packets.
Datastream:
A chunk of data sent
over a network. Larger
messages are divided into
packets that may arrive at the
destination in order,
out-of-order, or not at all.
Packet:
Data
added to packets to help
route them through the
network and reassemble
the original message.
Packet Metadata:
