phosphorescent is glowing in the dark;reusing old light it has stored, like a glow in the dark keychain fluorescent is something that glows when energy is applied to it, such as the fluorescent lightbulb As the name implies, phosphorescent comes from the element phosphorus. Many other substances which are not phosphorus can fluoresce at certain wavelengths of light. I agree phosphorous like sea waves sometomes.
The main difference between the two is the lasting power of the glowing. Phosphorescent materials glow for a longer period of time, and what's usually considered 'glow in the dark'. Fluorescent glows under blacklight, but this light does not remain at all afterwards.
Classically, phosphorescent substances absorb energy and then re-emit it for an extended time afterwards. Fluorescent substances "down-convert" higher frequencies to lower frequencies and don't emit after the energy source has been removed. Boosting the energy levels of orbiting electrons that fall back to lower levels and thus emit a photon, produce light. There are also other ways to do this--incandescence (by heat), bioluminescence (little creatures' chemistry), triboluminescence (friction), chemiluminescence (chemistry), electroluminescence (electrically), sonoluminescence (by sound waves), Bremstrahling (atomic braking radiation) and more.

Batteries provide a voltage difference.
In programming a "pipe" usually refers to a connection to a data source (aka a database). The difference between a queue and a pipe is that a queue usually caches some data from the data source while a pipe is just a connection to the data source.
A compiler transforms source code from a source file into low-level machine code, which is able to be executed directly on the CPU. A translator feeds the source code of a script into a different program that determines what the code is doing and executes the instructions.
