Data about data
Metadata
A base 10 number with ten possible different digits
Decimal Number
102 in decimal
210
The unique number assigned to each device on the internet
IP Address
Can continue to function even in the event of individual component failures. This is important because elemets of complex systems like a computer network fail at unexpected times, often in groups
Fault Tolerant
Data that changes discreetly through a finite set of possible values
Digital Data
A base 2 number with two possible different digits
Binary Number
11002 in decimal
1210
A protocol for sending data across the internet that assigns unique numbers to each connected device
Internet Protocol (IP)
Data added to packets to help route them through the network and reassemble the original message
Packet Metadata (will accept just "metadata")
Data with values that change continuously, or smoothly, over time
Analog Data
Error from attempting to represent a number that is too large
Overflow Error
1510 in binary
11112
A type of computer that forwards data across a network
Router
A protocol for sending packets that does error-checking to ensure all packets are received and properly ordered
Transmission Control Protocol (TCP)
A process for creating a sigital representation of analog data by measuring the analog data at regular intervals
Sampling
Error from attempting to represent a number that is too precise. The value is rounded.
Round-off Error
6510 in binary
10000012
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
A process for reducing the number of bits needed to represent something in which some informaiton is lost or thrown away. This process is not reversible.
Lossy Compression
The process of making data uniform without changing its meaning
Cleaning Data
A process for reducing the number of bits needed to represent something without losing any information. The process is reversible.
Lossless Compression
9710 in binary
1100001
A protocol for sending packets quickly with minimal error-checking and no reseding of dropped packets
User Datagram Protocol (UDP)
A group of interconnected computing devices capable of sending or receiving data
Computing Network
