Answer 1

basically it depends about the one's requirement. How many users you are expecting, what service application will be used, purpose of the farm etc. here are some hardware requirement:

Type                                           Memory        Processor   
Dev/stage/test server                          8GB RAM        4 CPU

All-in-one Database/Web/Service Application    24GB RAM       4 CPU

Web/SA server                                  12GB RAM       4 CPU
DB server (medium environments)                16GB RAM       8 CPU

DB server (small environments)                 8GB RAM        4 CPU
