  1. 1. lets your computer pretend it has a reliable connection to the other computer. The computers (including servers) at the two endpoints of a communication run TCP, which guarantees that packets arrive successfully.
  2. 4. maximum amount of data that can be sent in a fixed amount of time (for digital data, it is measured in bits per second). Higher bandwidth is better because the data will travel more quickly.
  3. 5. Wide Web a system of linked pages, programs, and files that uses the Internet.
  4. 7. switching means that the Internet sends short bursts of information, not long continuous strings.
  5. 9. system a group of computing devices and programs working together for a common purpose.
  6. 11. a small chunk of any kind of data (text, numbers, lists, etc.) and metadata (information about the data) that is passed through the Internet as a data stream.
  7. 12. a computer that passes information from one network to another. Your computer probably uses a router that is somewhere in your home to connect to your ISP.
  8. 15. the ability of the Internet to keep working as it grows.
  9. 17. device a physical object that can run a program, such as computers, tablets, cell phones, and smart sensors.
  10. 18. companies who sell Internet access to homes and institutions. The computers connected to the Internet and the connections among them don't belong to any one organization. Different ISPs provide the Internet to different communities. And typically, within a large organization (such as a university), the Internet connections are provided by the organization itself.

  1. 2. storage means storing it somewhere on the Internet, but you don't know where. The cloud service provider (Google, Dropbox, Amazon, Snap!, etc.) manages the actual storage location.
  2. 3. a computer network that uses open protocols to standardize communication. A computing device connected to an Internet-connected device is required to access the Internet.
  3. 6. lets your computer pretend it has a direct connection to another computer. The routers at every connection point on the Internet run IP, which transmits packets from one IP address to another.
  4. 8. network an interconnected computing system that is capable of sending or receiving data.
  5. 10. the process of finding a path from sender to receiver.
  6. 11. a set of rules that specify the behavior of a system.
  7. 13. the inclusion of back-up elements in case one part fails.
  8. 14. a sequence of directly connected computing devices that connect a sender to a receiver.
  9. 16. a pair of protocols that provide two levels of abstraction:
