difference in node stream and filter stream?

[Vuhelper]

Stream is an abstraction of a data source/sink. We need abstraction because there are lots of different devices (files, consoles, network, memory, etc.). We need to talk to the devices in different ways (sequential, random access, by lines, etc.) Streams make the task easy by acting in the same way for every device. Though inside handling of devices may be quite different, yet on the surface everything is similar. You might read from a file, the keyboard, memory or network connection, different devices may require specialization of the basic stream, but you can treat them all as just "streams". When you read from a network, you do nothing different than when you read from a local file or from user's typing
