Answer 2

for this question you need to know how computers work. they work in bytecodes. now what is bytecodes just google it.but we humans can't understand bytecodes easily so we have made assembly but still assembly is not very easy either so we have made other other languages like java, c++,etc.
now how programming languages work. we write codes and compile it, with compiling here i mean changing it in assembly, then assembly converts it in bytecodes it means flipping of bits and the program is executed.
To make new pro language you need to know about assembly, decide about your syntax and other things and made compiler for it.

Answer 3

look up compiler design
