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

Domain Name System (DNS)

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

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.
