The Internet is a global system of autonomous computer networks. It allows the use of Internet services such as the World Wide Web (WWW), E-Mail or FTP.
Technically standardized Internet protocols form the basis for the network communication. Precursor of the Internet is the computer network ARPANET developed in 1968 by the US Department of Defense. The aim was to link military and academic institutions within the United States. The first network consisted of just four computers from various universities which could transmit data to each other. Today almost half of the world's population uses the Internet. The distribution of the Internet contributed to a revolutionary change in all areas of life.
This week, we'll hear from people who've overcome all sorts of struggles in their lives: We meet a woman in Australia who was taken from her Aboriginal family decades ago and put in a foster home, a pastor with a criminal past who's helping kids survive in Mexico and women in Tanzania who marry other women to secure their future after their husbands have died. And: attacks on human rights.
Murder, surveillance and trolling - 2016 was not a good year for human rights defenders. According to Amnesty International (AI), it was a year of unparalleled global assault, clampdowns on civil society and rampant use of surveillance. 281 people were killed for defending human rights - up from 156 the year before. DW speaks with Guadalupe Marengo, head of AI's Global Human Rights Defenders Team.
