graphs

The graph shows internet speeds in different countries. High speed email is the standard that developed countries try to use. Dial up modems are now considered to be old fashioned and very slow. These are being phased out in developed countries. This graph shows that in general developed countries have a higher proportion of people with high speed connections as opposed to dial up connections. Also less developed countries have a greater proportion of dial up connections as opposed to high speed connections.
Although the Uk is a developed country just over half of the population have a high speed connection.  This is because there are a lot of upland and rural areas in the UK. This areas do not have high speed connections as it is difficult to lay the cables to provide it.

This graph shows how a lot of third world countries do not have wide-spread access to electricity. This lack of electricity means that a lot of people can not use computers. A lot of developing countries burn wood for energy. This is often used to provide heating for houses. Rarely wood is used in power stations but it is very inefficient.

developed coutries


Resources (developed countries)
Access to resources is not such a large problem in developed countries as it is in developing countries. Everyone has access to electricity but some people do not have access to the internet. This is generally the case for farmers in rural areas because they are not near towns or cities so they are not connected to the underground cables which provide internet access.
This can result in farmers not earning all they could. This is because the farmers who have internet access sell online and therefore get a better price than those without internet access.
This problem is being solved because they government plans to get all of the UK connected to internet by laying more cables. Some farmers have decided to buy and lay the cables themselves instead of waiting for the government.
Mobile phone signal can become disrupted in hilly regions which can make it difficult for people to communicate. This is not a major problem because as new phones get released they have stronger signals meaning they are less likely to get disrupted.

3rd world countries

Resources (3rd world)
In many 3rd world countries lots of people do not have access electricity supplies. This means that a lot of appliances will not work.  Another problem is that there is no network for mobile phones and the internet to connect to. This means the digital divide will increase because developed countries keep improving their networks while 3rd world countries can not.
This means that it is difficult for people in 3rd world countries to communicate with people elsewhere in the country. This creates similar problems as people not being able to afford technology. Farmers will not be able to communicate to get the best prices. Also contacting the emergency services is very difficult if there is no telephone network. 
A solution to this problem is the OX laptops. These laptops do not use much electricity because the screen is made visible by natural light and there are no moving parts that require electricity. This means an OX laptop can run for 24 hours non-stop. These laptops use alternative sources of electricity for power. These include solar cells built into the design so it can use solar power. Also the children can use a ripcord to generate electricity via movement. The laptops can connect with other laptops to form networks so children can communicate.
Mobile internet cafés are being built for poor areas. These travel the area and provide people with a connection to the internet when they are in the area.
