I have been reading much about bitcoins, . . . but I still do not understand the whole block architecture and/or model. . .
If there are specific parts of the system that are confusing you, feel free to ask about them here on bitcointalk.org. There are people here who have a really good understanding of how it all works, and many of them are willing to help those who are interested in learning more. If you are completely lost and don't even know where to start asking questions then this isn't as efficient a method of learning, and you might want to spend some time looking through these websites:
