Unit 2 Vocabulary

1. An agreed-upon set of rules that specify the behavior of some system
7. a group of interconnected computing devices capable of sending or receiving data.
8. the process of finding a path from sender to receiver.
11. 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.
14. Data added to packets to help route them through the network and reassemble the original message.
15. A type of computer that forwards data across a network

2. a machine that can run a program, including computers, tablets, servers, routers, and smart sensors
3. The unique number assigned to each device on the Internet.
4. a group of computing devices and programs working together for a common purpose
5. the maximum amount of data that can be sent in a fixed amount of time, usually measured in bits per second.
6. 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.
9. A protocol used on the internet for fast transmission of information but with minimal error checking
10. a protocol for sending data across the Internet that assigns unique numbers (IP addresses) to each connected device
12. the series of connections between computing devices on a network starting with a sender and ending with a receiver.
13. 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.
