Some Streams work with input, and some with output A. True B. False

The correct answer is: True.

A stream is a sequence of data that is processed one element at a time. Some streams work with input, and some with output. Input streams are used to read data from a file or other source, while output streams are used to write data to a file or other destination.

For example, a program that reads a text file and prints it to the screen would use an input stream to read the file and an output stream to print the text. A program that writes a log file would use an input stream to get the data to log and an output stream to write the data to the log file.

In general, any program that needs to read or write data from or to a file or other source will use a stream.
