  1. Some people are techno phobic. Actually, they don’t know how new technology works or how to use it. Others are worried about crimes such as hacking, fraud and phishing. They fear malware such as viruses and Trojans. They worry about their privacy, security or identity theft.
  2. The digital divide rests first of all on lack of electricity, as ICT depends primarily on electricity. In Malawi or Chad only around 10% of the population have access to electricity.
    Access to the Internet can also be limited for political reasons, as in North Korea, where the Net is mostly restricted to government officials or foreigners.
    By contrast, the penetration rate of countries like the Netherlands is over 95%.
    Developed countries have excellent technological infrastructure, so that people have easy access to both electricity and the Internet. Many people can also afford to buy computers, tablets, smart-phones or connected watches, which are widely used at home, at work and at school.
    By contrast, in developing countries, many people have other things to worry about, like food, health care or clean water. Buying technological devices is not at the top of their priorities.
  3. Access is difficult in mountainous, desert and rainforest areas. In some areas, basic infrastructure such as roads and bridges are missing.
