Across
- 2. An agreed-upon set of rules that specify the behavior of a system.
- 4. A physical component on a computer or device that provides connectivity to a network.
- 6. A group of interconnected computing devices capable of sending or receiving data.
- 10. Describes a method of compression in which original data can be completely recovered from the compressed data, without any loss of content.
- 11. A physical artifact that can run a program. Some examples include computers, tablets, servers, routers, and smart sensors.
- 13. A group of computing devices and programs working together for a common purpose.
- 15. Describes a method of compression in which data is lost in a way that cannot be recovered from the compressed data.
- 16. A network, developed under the direction of the U.S. Advanced Research Projects Agency (ARPA), that interconnected four university computers. It became the basis for the internet.
- 17. The extent to which a copy is identical to the original.
- 19. The capacity for the system to change in size and scale to meet new demands. The Internet was designed to be scalable.
- 20. The maximum amount of data that can be sent in a fixed amount of time, usually measured in bits per second.
- 21. The inclusion of extra components that can be used to mitigate failure of a system if other components fail. Many of the resources or components serve identical purposes.
Down
- 1. A system designed to work when components fail.
- 3. A sequence of directly connected computing devices that begins at the sender and ends at the receiver.
- 5. Small units of data transmitted on a network. Collected together, they compose some larger data, such as a document, a website, a movie, etc.
- 7. a unique numeric code that is assigned to networking hardware components (typically a network interface card or NIC) and is built into computers and mobile devices. The code is assigned by the manufacturer, includes their unique identification number, and never changes.
- 8. also known as "the web," is an information system of documents and other online resources that are interlinked by hypertext links. These resources reside and are exchanged on the internet, as the World Wide Web uses the Internet.
- 9. The body of a packet
- 12. Storing information using fewer bytes.
- 13. Data storage built into a hardware component or computer system to improve speeds by providing memory closer to the point of use.
- 14. Information about data, such as when, how, or by whom the data were collected, or what software was used to manipulate the data. In essence, it is data about data. For example, the piece of data may be an image, while the metadata may include the date of creation or the file size of the image.
- 18. Measure of delay in communication between two devices over a network.
