Across
- 2. the information about the packet is stored in the header
- 4. the maximum amount of data that can be sent in a fixed amount of time, usually measured in bits per second.
- 5. a programmer hides all but the relevant data about an object in order to reduce complexity and increase efficiency
- 9. the duplication of critical components or functions of a system with the intention of increasing reliability of the system
- 11. a small amount of data sent over a network, such as a LAN or the Internet
- 13. An agreed-upon set of rules that specify the behavior of some system
- 14. Protocol a protocol for sending data across the Internet that assigns unique numbers (IP addresses) to each connected device
- 15. There are two hierarchical Internet addressing systems, domain names (as shown below) and IP addresses. These address hierarchies work much like the postal system, which locates people first by state, then city, then street, then house number, then apartment, and then finally person.
Down
- 1. the property that enables a system to continue operating properly in the event of the failure of (or one or more faults within) some of its components
- 3. Control Protocol a standard that defines how to establish and maintain a network conversation through which application programs can exchange data
- 6. The unique number assigned to each device on the Internet.
- 7. a set of rules
- 8. is used to send short messages called datagrams but can be described as a ‘best-effort’ protocol; UDP is used over TCP for applications where speed matters such as video streaming since it is a faster transmission time
- 10. a small chunk of any kind of data: text, numbers, lists, etc
- 12. a device that forwards data packets along networks. It is connected to at least two networks, commonly two LANs or WANs or a LAN and its ISP's network. They are located at gateways, the places where two or more networks connec
