What Networking Is and Why It Matters
Welcome to Networking
What is a network?
A network is a group of devices that can communicate with each other. Devices can include computers, phones, printers, servers, and smart devices. Networking is the practice of connecting those devices so they can share information and resources.
Why networking exists
Networking makes it possible to share files, access the internet, use printers, watch streaming video, play online games, and communicate across long distances.
Everyday examples
When you send a message, open a website, or print to a shared printer, you are using a network. Even simple actions often depend on many devices working together.
