Does uploading a file to HDFS automatically store the files in a distributed manner?

I just started learning Hadoop, and I am little confused regarding how the data is stored in a distributed manner. I have an MPI background. With MPI, we typically have a master processor that sends out data to various other processors. This is done explicitly by the programmer.

With Hadoop, you have a Hadoop Distributed File System (HDFS). So when you put some file from your local server into HDFS, does HDFS automatically store this file in a distributed manner without anything needed to be done by the programmer? The name, HDFS, seems to imply this, but I just wanted to verify.
