A computer network and the internet are related but distinct concepts:
- **Computer Network**: This refers to a collection of interconnected computers and devices that share resources and information within a specific, often localized, environment. Networks can be small, like a home network with a few devices, or larger, like a corporate network connecting multiple offices. Networks can be private and controlled by an organization or individual.
- **Internet**: This is a vast, global network of networks that connects millions of private, public, academic, business, and government networks. It allows devices worldwide to communicate and share information through standardized protocols. The internet is essentially a global network infrastructure that enables access to a multitude of services, including websites, email, and online applications.
In summary, while a computer network refers to a specific setup of interconnected devices, the internet is a massive, interconnected system of networks that spans the globe.
