Difference between Wi-Fi and Ethernet

  • Last Updated : 09 Sep, 2021

WiFi stands for Wireless Fidelity. WiFi uses Radio waves to provide wireless high-speed internet and network connections. A WiFi connection is established using a wireless adapter to create hotspots. WiFi antennas size is small enough to be placed on a very small router. WiFi can be used to connect with printer, computers, gaming consoles, and many more. 

Ethernet is most widely used LAN Technology, which is defined under IEEE standards 802.3. The reason behind its wide usability is Ethernet is easy to understand, implement, maintain, and allows low-cost network implementation. Also, Ethernet offers flexibility in terms of topologies which are allowed. Ethernet generally uses Bus Topology. Ethernet operates in two layers of the OSI model, Physical Layer, and Data Link Layer. For Ethernet, the protocol data unit is Frame since we mainly deal with DLL. In order to handle collision, the Access control mechanism used in Ethernet is CSMA/CD. 

Attention reader! Don’t stop learning now. Get hold of all the important CS Theory concepts for SDE interviews with the CS Theory Course at a student-friendly price and become industry ready.


Now, we shall see the difference between WiFi and Ethernet: 

1It is a networking technology that allows mobile devices to make wireless connection.It is a standard communication protocol used in wired local area network.
2Wifi is defined under IEEE 802.11x standards where x stands for various WiFi versions.Ethernet is the second name given to the prevalent Packet Switched LAN technology.
3Wi-Fi means no wires and no wires mean no ports.Ethernet requires lots of cabling so there is no mobility.
4It is flexible in nature.It is not flexible in nature.
5It offers mobility and flexibility but offers latency in speed and less efficient in comparison.It offers faster data transfer speeds and more efficient
6It is easy to install and deploy.It is difficult to install and time-consuming.
7Encrypted data is flow over wireless network.Data flow is not require to be encrypted over Ethernet.
