Global system of interconnected computer networks that use the internet protocol suite (tcp/ip) to link several billion devices worldwide. Misconception that the terms internet and world wide web are synonymous. Internet is the infra upon which many services are made available. The web is a service on the internet and alongside email and message, is the most popular. Distributed ownership: publicly accessible; no single entity owns it, regulates its use. Has many owners but no one who centrally controls it. This limits regulation, fostering experimentation, and ensuring widespread access leading to significant growth. Multiplicity of devices: internet is a digital network consisting of millions of smaller digital neworks. Each of these smaller digital networks encompasses a collection of digital devices, called nodes.
