The purpose of a .bashrc file is to provide a place where you can set up variables, functions and aliases, define your (PS1) prompt and define other settings that you want to use every start you open a new terminal window

./script runs the script as an executable file, launching a new shell to run it
source script reads and executes commands from filename in the current shell environment

sh stands for "shell" and shell is the old, Unix like command line interpreter. An interpreter is an program that executes specific instructions written in a programming or scripting language. So basically you say "Execute that file for me".
