Hadoop is a combination of frameworks each having its own purpose,
HDFS -> Distributed data storage, (i.e., if you have to manage huge amount
of data which may NOT fit into single machine then DFS (distributed file
system) is a way through which you can store and manage your data across
multiple machines)
Mapreduce -> Hadoop mapreduce is a parallel processing batch oriented
framework where you can run a single task in parallel across multiple
Hbase -> is a distributed NOSQL data base (there are major differences b/w
a relational data base and Hbase)
and many other frameworks in the Hadoop eco-system includes Mahout, Hive,
Pig etc has their own applications.

One important note is that Hadoop run on a commodity hardware.
