In some parts of the world there is a large digital divide. Sometimes it is just in half of a country, or just a region, for example Africa. As with other things like education or transport, some people have things that others don't have. There are big cities where technologies are cheap and there are many villages and rural communities where there is no digital/electronic technology. In this case the digital divide creates other problems. Because a part of the country is rich and another part is poor, there are often problems with trading and connections.
