Difference between WiFi and Ethernet
WiFi
WiFi, Wireless Fidelity is a small network where smartphones, computers or other networkable device is connected to each other wirelessly within a small range and share internet using hotspots. WiFi uses radiofrequency waves for wireless highspeed internet and network connections. A WiFi antenna size is very small and can be put on small routers. Wifi can be used to connect printers, computers, gaming consoles, mobile and so on.
Ethernet
Ethernet is a widely used LAN standard. It is defined under IEEE 802.3 standards. It is very easy to understand, implement, maintain and is a low-cost implementation. It generally uses Bus Topology but other topologies can also be used. It is part of the Physical and Data Layer of the OSI model.
The following are some of the important differences between WiFi and Ethernet.
| Sr. No. | Key | WiFi | Ethernet |
|---|---|---|---|
| 1 | Concept | WiFi is a wireless network to connect nearby devices to each other and share the internet via hotspots. | Ethernet is a LAN network standard used in wired LAN. |
| 2 | IEEE Standard | WiFi is based on IEEE 802.11x specifications where x is WiFi versions. | Ethernet is based on IEEE 802.3 specifications. |
| 3 | Connection | Devices can be connected without wires, without ports. | Ethernet is wired and hence no mobility. |
| 4 | Flexibility | Wifi is highly flexible. | Ethernet is not flexible. |
| 5 | Efficiency | Wifi is less efficient and has latency in network connections. | Ethernet is more efficient and provides more speed. |
| 6 | Installation | Wifi installation/deployment is easy. | Ethernet installation is difficult and time-consuming. |
| 7 | Encryption | Wifi data is encrypted during transfer. | Data is not required to be encrypted during transfer in ethernet. |
