U2 Internet Definitions Flashcards
A machine that can run a program, including computers, tablets, servers, routers, and smart sensors.
Computing Device
A group of computing devices and protmas working together for a common purpose.
Computing System
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
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.
IP
The unique number assigned to each device on the Internet
IP Address
A type of computing device that forwards data across a network
Router
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 components failures. This is important because elements of complex systems like a computer network fail at unexpected times, often in groups.
Fault Tolerant
A chunk of data sent over a network. Larger messages are divided into packers that may arrive at the destination in order, out-of-order, or not at all
Packet
A protocol for sending packets quickly with minimal error-checking and no resending of dropped packets
UDP
A protocol for ending packets quickly with minimal error-checking and no resending of dropped packets
TCP
