I found this phrase in my computer book and now I want to know the meaning of the phrase 'Information Junky'. Please tell me. Thanks in advance.
Heh, that's a fun one.
"Junky" is just another way of spelling "Junkie", which refers to an addict (often a drug addict) compelled to take their addictive substance of choice.
So an information junkie is an addictive consumer of information, often someone who reads a lot on a topic to get more information before actually acting on that information.
Despite the connection in concept to a serious drug habit, the phrase is generally used in a lighthearted way and said without concern, as being an "Information Junkie" is almost always totally harmless.
