The Digital Devide

The Digital Divide

Define Digital Divide.

A) Digital Divide is a gap between those who use the ICT in their life and those who doesn't. In another word, its Information Literacy.

Those people maybe cant afford to buy a hardware, or don't have the enough knowledge to use it.

Identify the main effects of digital divide on society.

A) The society that have no ICT skills cant use the tremendous amount of information in the web to educate people. People cant use the positive impact of ICT to explore in the web.

The lack of ICT unable a society to compete to a developed one, thus falling behind in economic standers which lead to low income for the society. This lead to some living issues such as: Hunger and poorness.

On the other hand, societies that have internet access and impressive ICT skills are controlling the world. The use of e-commerce and e-banks are making the people life much easier and enjoyable. They have enough time to develop more and more and expand the digital gap significantly.

Explain a real case study on bridging the digital divide gap.

A) The bridging of digital divide gap took place in Uganda.

A group of people installed a Question Box to places where no internet access was there and connected that question box to someone with internet access to answer different type of question about health, farming, fishing and more. The system was efficient, easy to use and helpful.It was like an Expert System.

People benefited a lot from it. For example, some farmers were having a diseases issue in their bananas. That disease was spreading in all the bananas destroying the crop, which was the only food sources for the farmers and their families. Fortunately, after using the question box and asking experts about the problem, they solved the problem by eradicating virus in the bananas, therefore saving life of many families.
