| A type of
software or program that sorts information from the Internet as it
comes onto your computer. It usually sorts it by its content.
In computer programming, a
filter is a program or section of code that is designed to examine
each input or output request for certain qualifying criteria and
then process or forward it accordingly. This term was used in Unix
systems and is now used in other operating systems. A filter is
"pass-through" code that takes input data, makes some specific
decision about it and possible transformation of it, and passes it
on to another program in a kind of pipeline. Usually, a filter does
no input/output operation on its own. Filters are sometimes used to
remove or insert headers or control characters in data. |
