wi-fi vs blue tooth  

I use wi-fi for my internet connection. It's much easier to access rather than the cable wired DSL's. For the Blue tooth, I used it in my phone to send and receive files from other phones and connect it with my computer. They are both different entities for me but both were equally important.

ethernet has possess significant features of wireless-fidelity.
ethernet has maximum spped and it has alot branch connections compared to other wireless meachnisms.
