14.104 Multicore Storage Hierarchies, NUMA

My book "Patterns in Data Management" is now available both as an ebook or a print book (with color graphics!). See: amzn.to/1Ts3rwx This book is not a standard textbook on database techniques. This book was written extending and complementing preexisting educational videos (including this one).
How are the two terms core and CPU related? How does a typical multicore storage hierarchy look like? What is different compared to the storage hierachy? Why isn’t L1 shared as well among multiple cores? What is a Non-Uniform Memory Access (NUMA) architecure? What is different compared to the multicore architecture? What does this imply for accesses to DRAM? Bonus Question: How again does this relate to The All Levels Are Equal?

i do not understand the way your videos are numerated like 14.104 14.001 13.46 , how does the numeration-system works?

14 is the year of the lecture (it will start in April 2014);
the first digit after the "." is the section, Section 1 for this video;
the following two digits are the number of the video within that section, here video 04
