Answer / a

The DataInputStream works with the binary data, while the
BufferedReader work with character data.

All primitive data types can be handled by using the
corresponding methods in DataInputStream class, while only
string data can be read from BufferedReader class and they
need to be parsed into the respective primitives.

DataInputStream is a part of filtered streams, while
BufferedReader is not.

DataInputStream consumes less amount of memory space being
it is binary stream, where as BufferedReader consumes more
memory space being it is character stream.

The data to be handled is limited in DataInputStream, where
as the number of characters to be handled has wide scope in
BufferedReader.

An important difference between the ...Stream classes and
the ...Reader/...Writer classes is that streams work with
binary data (in other words, raw bytes), while readers and
writers work with character data. In going from one to the
other there's always an encoding or decoding of data
involved.

The en-/decoding step can't be done in a meaningful way
unless one knows what encoding was used. Common encodings
are US-ASCII, UTF-8 and other Unicode variants, MacRoman,
ISO-8859-1 and CP1252. Furthermore, each platform (Windows,
Linux, OS X, ...) has its own default encoding, so if no
encoding is specified, the JVM will choose one - which may
well be the wrong one.
