Through intuitive analogies, I was able to easily and accurately learn about CPU, motherboard, RAM, HDD/SSD, which may be unfamiliar to computer illiterate people, and I was able to get a feel for how to estimate the daunting task of assembling a computer! In particular, it was very helpful that he showed me the motherboard screen and told me where to plug what in. This lecture is like a ray of light for computer illiterate people :)
