Wi-Fi is a technology that connects your computer to an internet access point using radio signals. Also this technology is very similar to smartphones and TVs as they all use radio waves. Wi-Fi is a very important part of technology today as it allows people to connect with each other and to access information that was probably difficult to obtain before Wi-Fi. Wi-Fi is just accessing the internet like you are directly connected with an Ethernet cable however with Wi-Fi you can access the internet wirelessly as long as you are in the routers radius. Wi-Fi is a very important part of peoples live and there are many companies that make a lot of money form just selling their Wi-Fi packages such as Virgin Media and BT.

The speed can also be slowed down by obstacles coming in the way of the router to the Wi-Fi spot and this slows the user down as the radio waves have to go through walls to reach the destination, also many other devices interfere with the radio waves such as baby monitors. One more disadvantage with Wi-Fi is that if you want fast speeds then you have to upgrade your speeds with your internet provider as the faster speed the more expensive the price however most people use the slowest speed because it is very cheap.
