WiFi is a wireless networking protocol that allows devices to communicate without internet cords. It is technically termed or represented by a type of wireless local area network (LAN) protocol based on the 802.11 IEEE network standard.
WiFi uses radio waves to provide wireless high-speed Internet and network connections. It is often mistaken to be the short form of “Wireless Fidelity” but it’s not officially approved by the Wi-Fi Alliance. Wi-Fi is termed as a wireless connection that lets other devices such as phones, tablets, computers to connect to it.
It is supported by many applications and devices including video game consoles, home networks, mobile phones, major operating systems, and other types of consumer electronics.
The main requirement for WiFi is that there should be a device that can transmit the wireless signal, like a router, phone, or computer.
Ethernet is an array of networking technologies commonly used in local area networks (LAN). Metropolitan area networks (MAN), and wide area networks (WAN. It was commercially introduced in 1980 and first standardized in 1983 as IEEE 802.3. It is said that Ethernet was originally developed by Xerox. Ethernet has been introduced to support higher bit rates and longer link distance.
When the Ethernet was introduced, the first version i.e 10BASE5 Ethernet used coaxial cable as a shared medium. While with the changing of years and its updation, the newer Ethernet variants use twisted pair. And fiber optic links in conjunction with switches.
Ethernet has evolved to include higher bandwidth. It has also improved medium access control methods and different physical media i.e from coaxial cable to twisted pair and fiber optic. Systems that uses Ethernet, while their communication divide data streams into packets. Which are known as frames? Frames include source and destination address information, as well as mechanisms. These are used to detect errors in transmitted data and retransmission requests.
Comparison between Wi-Fi and Ethernet :
Setup and Maintenance: Both the WiFi and Ethernet connections are easy to setup. Ethernet requires some additional accessories such as the modem in a standard living room setup. While the WiFi may require the installation of a receiver. Once this receiver radio is in place, the internet service provider (ISP) can adjust the transmitter radio to get the dedicated connection running.
Any changes can be made easily to either of the connections and there are no difficulties in their maintenance as well.
Earlier when the WiFi was introduced, it provided a speed of around 54 Mb/s whereas the Ethernet provided a speed of around 1000 Mb/s at its initial stage. But this scenario has been completely changed over the past years. Now the Wi-Fi offers a speed of up to 1 GB/s while the Ethernet is still stuck to its 1000 Mb/s.
Well with this comparison we can clearly say that Wi-fi is faster than Ethernet but that, not the case always. Theoretically, Wi-Fi may be faster but practically its a different thing.
WiFi is affected by various factors of our environment.i.e the buildings, trees, etc as the radio waves are transmitted in the air. So because of all these factors, we don’t get the required speed offered by the Wi-Fi. But this is not the case in Ethernet as it is through a solid medium. Consists of wires with no interference in between us so we can get our required speed here.
So talking about security, WiFi has very strong security as encryption takes place which is very hard to crack. The WPA/WPA2 encryptions are very secured. Now the question is, Can still it can be cracked ?? Yes, it can be cracked because in this case the connection or information is in the medium of radio waves. It’s in the air and so the encryption can be cracked. But this is not the case in Ethernet as here the information is carried in a solid medium i.e wires.
So wifi is secured too but as it has a vast range as compared to Ethernet. Anyone can hijack or steal your information. As it is transmitted in air and as Ethernet comparatively has a smaller range. And also a connection in a solid medium. It becomes difficult to hijack information here.
Latency: Latency is the amount of time a message takes to travel across a system. In a computer network, it denotes an expression of how much time it takes. So for a packet of data to get from one point to another. It is sometimes measured as the time required for a packet to return to its sender. In the networking or online gaming world, latency is also known as ping.
Latency matters a lot while playing an online game – while playing online games. If you want your reaction time to be quick then in this case Ethernet would be a better option. As it’s in a solid medium.
On the other hand, if you are just listening to songs, watching a movie or surfing the web. Then in this case latency won’t matter much and you can use any of the connections – either Wi-Fi or Ethernet.
