Net neutrality is the principle that an internet service provider (ISP) should give consumers equal access to all legal content regardless of its source.
To put it another way, if the networks which form the bedrock of the internet were a motorway, then under net neutrality, there wouldn’t be fast lanes for cars and slow lanes for lorries. Motorists wouldn’t be able to pay to use a faster route. All data regardless of its size, is on a level playing field.
In practice what this means is that ISPs – the biggest ones in the US include Comcast, Charter and AT&T – cannot block content, speed up or slow down data from particular websites because they have been paid to do so. And they can’t give preferential treatment to their own content at the expense of their competitors… More at the BBC.
