What are the differences between a CISC and a RISC machine?

CISC asm:
TERM EQU 19 console device no. (19 = typewriter)
ORIG 1000 start address
START OUT MSG(TERM) output data at address MSG
HLT halt execution
MSG ALF "HELLO"
ALF " WORL"
ALF "D "
END START end of program

RISC asm:
string BYTE "Hello, world!",#a,0 string to be printed (#a is newline and 0 terminates the string)
Main GETA $255,string get the address of the string in register 255
TRAP 0,Fp
