It can be easy to get confused by all of the terms and phrases used to talk about the internet. Two of the most commonly encountered words are broadband and WiFi, and it will certainly help you to make the best decisions for your household if you understand what these mean.
Broadband and WiFi are not the same thing. Broadband is the name of the type of internet connection that is used by many homes and businesses, and is delivered by an internet service provider, or ISP. This means that broadband is the route along which data, or information such as music, films, files and other content, travels between devices. It's called broadband because, unlike the early forms of internet delivery, which used a single telephone landline to carry this data, broadband uses many lines (or cables). It is literally a broader bandwidth of internet transmission and means that much more data can be transmitted faster.
WiFi, meanwhile, is the name of a type of technology which can be used to connect a device such as a computer, smartphone or tablet to broadband internet services. A WiFi connection is wireless, using radio frequencies to transmit data. This offers certain advantages over other technology that can be used to access the internet, such as a LAN cable linking the router and the device.
