Unit 2 Vocab Flashcards
computing device
a machine that can run a program, including computers, tablets, servers, routers, and smart sensors
computing system
a group of computing devices and programs working together for a common purpose
computing network
a group of interconnected computing devices capable of sending or receiving data
path
the series of connections between computing devices on a network starting with a sender and ending with a receiver
bandwidth
the max amount of data that can be set in a fixed amount of time, usually measured in bits per second
protocol
an agreed-upon set of rules that specify the behavior of some system
IP Address
the unique number assigned to each device on the Internet
Internet Protocol (IP)
a protocol for sending data across the Internet that assigns unique numbers (IP Addresses) to each connected device
Router
a type of computer that forwards data across a network
redundancy
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
fault tolerant
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
datastream
information passed through the internet in packets
packet
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 metadata
data added to packets to help route them through the network and reassemble the original message
transmission control protocol (tcp)
a protocol for sending packets that does error-checking to ensure all packets are received and properly ordered
