Ethernet
Definition
Ethernet is the traditional technology for connecting devices in a wired local area network (LAN) or wide area network (WAN). It enables devices to communicate with each other via a protocol — a set of rules or common network language.
Why It Matters
Ethernet provides a faster, more stable, and more secure network connection than Wi-Fi. It is the standard for wired networking in homes, offices, and data centers.
Contextual Example
For online gaming or large file transfers, it is often best to connect your computer directly to your router using an Ethernet cable to get the lowest latency and fastest, most reliable speeds.
Common Misunderstandings
- The Ethernet port on a device is also called an RJ45 port.
- Ethernet speeds have evolved from 10 Mbps to 100 Mbps, to 1 Gbps (Gigabit Ethernet), and even up to 100 Gbps and beyond in data centers.
