The One Laptop Per Child (OLPC) project produces and distributes laptops to developing countries. The device is billed as a $100 laptop for education and entertainment for children. The project was launched by then United Nations Secretary-General Kofi Annan at the United Nations Information Society Summit held in Tunis, the capital of Tunisia, on November 16, 2005. Previously, the first laptop prototype was demonstrated by OLPC project founder Nicolas Negroponte.

The OLPC XO laptop was designed by Nicholas Negroponte, co-founder of the Massachusetts Institute of Technology (MIT) Media Lab. Designed by Eve Bear Fuseproject. Its manufacturer is Quanta Computer. The laptop was developed by the non-profit organization OLPC.

The laptop contains digital versions of children's textbooks corresponding to each country's national education system. In 2006, it sold for $188. In 2008 the price rose to $100. It was later discounted to $50 as part of a "Buy One, Get One" promotion.

The $100 laptop uses flash memory instead of a hard drive. This is a multimedia laptop. It runs on Fedora Linux operating system. It uses Wi-Fi wireless technology to connect to the internet. The OLPC XO-4 model was launched in 2012. It has been expanded to include touch technology.
