Unit 2: The Internet Vocabulary Bandwidth - the maximum amount of data that can be sent in a fixed amount of time, usually measured in bits per second Computing Device - a machine that can run a program, including computers, tablets, servers, routers, and smart sensors Computing Network - a group of interconnected computing devices capable of sending or receiving data. Computing System - a group of computing devices and programs working together for a common purpose Path - the series of connections between computing devices on a network starting with a sender and ending with a receiver 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 Protocol - An agreed-upon set of rules that specify the behavior of some system 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. 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 Router - A type of computer that forwards data across a network 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 Domain Name System (DNS) - the system responsible for translating domain names like example.com into IP addresses HyperText Transfer Protocol (HTTP) - the protocol used for transmitting web pages over the Internet World Wide Web - a system of linked pages, programs, and files
