I sometimes end up googling the meaning of a term, like "multiplexing". But the search results are written for many different audiences, and by many different authors, since Google searches a huge variety of sources.

I'm looking for a resource to search for a software engineering term and get a like to be able to search for a software engineering term like "multiplexing" and get an answer to a query that is written by an expert, similar to a searchable textbook or encyclopedia (to contrast with "crowdsourced" reputation based sources like wikipedia, stackoverflow, or quora).

I'm wondering if anyone knows of a resource like this? Thank you.
