The Internet

3. a group of interconnected computing devices capable of sending or receiving data.
7. the inclusion of extra components so that a system can continue to work even if a individual components fail, for example by having more than one path between any two connected devices in a network.
8. the maximum amount of data that can be sent in a fixed amount of time, usually measured in bits per second
9. A group of computing devices and programs working together for a common purpose.
10. A type of computer that forwards data across a network
12. Information passed through the internet in packets.
13. a protocol for sending data across the internet that assigns unique numbers (ip addresses) to each connected device.
15. An agreed-upon set of rules that specify the behavior of some system.

1. 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.
2. A protocol for sending packets quickly with minimal error-checking and no resending of dropped packets
4. Data added to packets to help route them through the network and reassemble the original message.
5. a machine that can run a program, including computers, tablets, servers, routers, and smart sensors.
6. A protocol for sending packets that does error-checking to ensure all packets are received and properly ordered
11. the unique number assigned to each device on the internet.
14. the system of connections between computing devices on a network starting with a sender and ending with a receiver.
15. 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.
