+# Trie
+A type of tree structure designed for mapping a set of keys to associated values. Each level of the tree is indexed by a character in the key to determine the next node to look at. The bitwise variant of this structure uses the bits of an integer value to index into the structure and retrieve the corresponding data.

 # Zettelkasten
 
-An interesting approach to note taking that has similarities to a wiki. Should investigate making awiki support some of the ideas here:
+An interesting approach to note taking that has similarities to a wiki. Originally implemented using numbered index cards. Cards can be cross referenced and can link to one another by id. Each card covers one topic in a manner such that the card can be read and is useful standalone (The cards are atomic). Each card has a defined home in the catalog (determined by ID) thus making it easy to perform cross referencing and find cards later.
+
+In digital form, each note is typically given a unique ID based on the date and time it was created. This ID is then used to link notes together and build topical trees. In addition, notes can be "tagged" to indicate related topics or otherwise categorize the note. These tags can then be used to find the notes later.
