it really is i used cable and then i switched to wifi. wifi is really slow
The ethernet cable needs to be connected to a router or modem and it works fine although I chose to purchase the CAT 6 ethernet cable. The speed test for the internet connection is faster with the ethernet connection than with the WiFi connection and I have never lost a connection like I did with WiFi
Yes, if you wish to use your laptop away from home using someone else's wifi network, or using a hotspot. At home, rather than wifi, you could use an ethernet cable to wire directly to your router.
Cat 6 can handle up to 10G (10000Mbit/s) while 802.11n (WiFi) can handle up to 200Mbits/s. Basically cat6 is way faster than WiFi.
If you have DSL internet, you can use a WiFi router with it. That's usually provided by the phone company.
A wifi phone is just a phone that can use wifi. You would connect it to a wifi network to get a better signal for faster web browsing than a cell tower.
Wifi - by a long shot
Not all external peripheral devices need a cable. There are a growing number of devices that use wifi (wireless and no cable required). You can use a wifi keyboard and a wifi mouse. There are wifi printers, and so on.
broadband is faster that wifi
Internet like Wifi is wireless, unlike cable which is usually a modem hooked up and it flows through the cable connection.
wifi is wireless internet. so you dont need to run a ethernet cable to your device to have internet if it is wifi ready.
