Computing Network

a group of interconnected computing devices capable of sending or receiving data.

Computing System

a group of computing devices and programs working together for a common purpose

Datastream

Digital Divide

differing access to computing devices and the Internet, based on socioeconomic, geographic, or demographic characteristics

Domain Name System (DNS)

The system responsible for translating domain names like example.com into IP addresses

Fault Tolerant

Protocol

Redundancy

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.

Router

A type of computer that forwards data across a network

Scalability

The capacity for the system to change in size and scale to meet new demands.

World Wide Web

a system of linked pages, programs, and files.
