无线上网：
WiFi代表无线保真。 WiFi 使用无线电波提供无线高速互联网和网络连接。使用无线适配器建立 WiFi 连接以创建热点。 WiFi 天线的尺寸足够小，可以放置在非常小的路由器上。 WiFi 可用于连接打印机、计算机、游戏机等。
以太网：
以太网是使用最广泛的 LAN 技术，它是在 IEEE 标准 802.3 下定义的。其广泛可用性背后的原因是以太网易于理解、实施、维护并允许低成本的网络实施。此外，以太网在允许的拓扑方面提供了灵活性。以太网一般采用总线拓扑。以太网在 OSI 模型的两层中运行，物理层和数据链路层。对于以太网，协议数据单元是帧，因为我们主要处理DLL。为了处理冲突，以太网中使用的访问控制机制是 CSMA/CD。
现在，我们将看到 WiFi 和以太网之间的区别：
| S.NO. | WI-FI | ETHERNET |
|---|---|---|
| 1 | It is a networking technology that allows mobile devices to make wireless connection. | It is a standard communication protocol used in wired local area network. |
| 2 | Wifi is defined under IEEE 802.11x standards where x stands for various WiFi versions. | Ethernet is the second name given to thePrevalent Packet Switched LAN technology. |
| 3 | Wi-Fi means no wires and no wires mean no ports. | Ethernet requires lots of cabling so there is no mobility. |
| 4 | It is flexible in nature. | It is not flexible in nature. |
| 5 | It offers mobility and flexibility but offers latency in speed and less efficient in comparison. | It offers faster data transfer speeds and more efficient |
| 6 | It is easy to install and deploy. | It is difficult to install and time-consuming. |
| 7 | Encrypted data is flow over wireless network. | Data flow is not require to be encrypted over Ethernet. |
