Question 1

,

Generations of programming languages

First generation

Answer 1

programmed directly in binary using wires or switches

Question 2

,

Generations of programming languages

Second generation:

Answer 2

assembly language. Human readable, converted directly

to machine code

Question 3

,

Third generation:?

Answer 3

: high-level languages, while loops, if-then-else, structured.

Most programming today, including object-oriented

Question 4

,

Fourth generation:

Answer 4

1990s natural languages, non-procedural, report

generation. Use programs to generate other programs. Limited use today.

Question 5

,

Key idea:

Answer 5

Regardless of the language of writing, computers only process

machine code

Question 6

,

All non-machine code goes through a translation phase into machine code.

Answer 6

– Code generators

– Compilers

– Assemblers

Question 7

,

Language translation process

Answer 7

– High level languages use comparison constructs, loops, variables, etc.

– Machine code is binary, directly executed by CPU

Question 8

,

– Convert high level language to if/goto.
