Just to add more points, it's a cluster of machines wherein you can run a distributed application. Think of it as one server virtually spread across multiple machines located in different locations. For instance, if you write a application which consumes 10GB RAM, but you do not have one physical machine to run your application. If you have 10 separate machines each having 1GB RAM, you could run your application using this system. Google search is a typical application which is built on this concept. They have 1000s of low-end machines interconnected using a distributed system. So even if one machine goes down, the remaining 999 machines would ensure to fulfill the user request. They share a common file system called BigTable and/or Google File System(GFS). Similarly, on the open source front Hadoop is meant to be used as a distributed computing platform. It has it's own BigTable alike file system MapReduce to facilitate this setup. Many leading software firms including Yahoo! and Amazon use Hadoop. If i'm right, Yahoo! has a setup wherein they have interconnected around 2000 nodes using Hadoop and it is one of the largest implementation afaik.
