Brazil adopts open-source software

In Brazil's Ministry for Cities, staff are busily at work.

The scene is much like any other modern office: an open-plan work space crammed with desks, telephones and computers.

But there's one big difference. The word 'Microsoft' is nowhere in sight.

Instead, computers here now use the Linux operating system. It has many similar functions to Microsoft's Windows - but unlike Windows, it is available for free. LINK
