A good answer might be:

256, which is 2⁸ (2 to the 8th power).

Of course, fundamentally all files consist of 8-bit bytes. As far as the computer's electronics is concerned all files look alike. Those files that contain bytes that are intended to be interpretted as characters are called text files, and those that contain bytes that are intended for other interpretations are called binary files.

The the terms "text file" and "binary file" are somewhat misleading. Many of the bytes in a word processor file are interpretted as font, formatting, graphics, and other non-character information, so it is a binary file. It could not correctly be read with a Reader stream.

The picture shows the top of the IO stream hierarchy: This chapter will look at the OutputStream class.

QUESTION 2:

Can a value from an int variable be written to a file without translating it into characters?
