pipeline

Post by abalfazl »

Hello


From Zend PHP certification study guide(chapter 10):



Data in a stream flows along one of two pipelines:

Data sent down a stream from your php script to the destination file or network server flows down the write pipeline.


Data retrieved from the file or network server flows up the read pipeline.


What is the pipeline?

May someone explain about this mechanism?

GOOD LUCK

Unless I'm mistaken, this is what it's talking about, but in a much larger context:
http://en.wikipedia.org/wiki/Pipeline_(software)

Let's see... It's basically like cin and cout, if you know any C++.

There are two pipelines, a and b. If the data goes from the network to the file, it goes through a. If it goes through the file to the network, it goes through b. That make more sense?

Code: Select all

NETWORK

Edit: ok, the forums don't like the params, so just copy and paste it.
