I know this is a very difficult question, but if you could choose only one book to convey the main ideas in each of those four areas you mention (software architecture, system design, algorithms, data structures), what would they be? I ask because I'm looking to buy some good books on the subjects.

My personal favourite is "Operating Systems: Design and implementation" by Tanenbaum, it covers all the subjects you mention.
