Free and open-source software

What is Free and Open-Source Software?

Free and open-source software, often called FOSS, is a special kind of computer program. Anyone can use it, share it, change it, and let others use their changes. Unlike regular programs you buy and can't change, FOSS lets everyone see how it works and improve it. This idea comes from beliefs about sharing and freedom in technology.

FOSS started from old ideas of sharing computer programs in the 1960s and 1980s. Today, many important systems like Linux distributions and BSD are FOSS. They help run servers, computers, phones, and many other devices. People choose FOSS because it can save money, keep information safe, and let users control their own technology.

There are groups and communities that support FOSS. They believe in sharing and working together, even if they don’t always agree on every detail. These groups help make and spread FOSS around the world.

Why Do People Use FOSS?

People who use free and open-source software can use, learn about, change, and share the software however they want. This means they can make the software work better for them and share their changes with others. Unlike other software, FOSS lets people see and check the code themselves, which can help keep things safe and fair. It often costs nothing, so more people can try and compare different tools.

FOSS has many good points, but it can sometimes be harder to get help or make sure it works with other tools. Because it depends on volunteers, there might be fewer features or slower updates than with software made by companies. Still, many governments and big groups around the world use FOSS because it gives them control and can be more reliable.

FOSS Around the World

Many countries have started using free and open-source software in their governments. For example:

• The government of Argentina gave kids in public schools free laptops with Huayra GNU/Linux, a FOSS operating system.
• In Austria, Vienna switched from Microsoft Office to OpenOffice.org and from Microsoft Windows to Linux.
• The Brazilian government helped give cheap computers with Linux to poorer communities.
• The city of Sault Ste. Marie, Ontario in Canada opened up its software development to save money and work with other towns.
• Ecuador passed a law to move the public sector to Libre Software.
• In France, the French Gendarmerie Nationale plans to switch to Ubuntu by 2015.
• In the City of Munich in Germany, over 15,000 computers were changed to a Linux system called LiMux.
• The Government of Kerala in India supports FOSS in its IT policy.
• The Italian military is moving to LibreOffice and the OpenDocument Format.
• In Malaysia, the public sector saved money by using open-source software.
• In Peru, the government voted to use open source across all its bodies.
• The City of Barcelona in Spain is changing its computers to use open-source software.

FOSS helps countries save money, keep control of their technology, and work together to make better software for everyone.
