Study Notes
Low-Level Programming Languages
- First generation programming languages (1st GL) include Machine Language, which is the only language that computers directly recognize.
- Machine languages use a series of binary digits (1s and 0s) to represent instructions, which can be time-consuming and tedious.
- Binary digits correspond to the on and off electrical state.
Second Generation Programming Languages
- Second generation programming languages (2nd GL) include Assembly Language, which uses symbols and instruction codes to represent machine codes.
- Assembly languages are difficult to learn and understand, and require conversion to machine language before execution.
- An assembler is used to convert the assembly language source program into machine language.
Third Generation Programming Languages
- Third generation programming languages (3rd GL) are procedural languages that use English-like words and arithmetic symbols to write instructions.
- 3GLs are simpler to develop than low-level languages, but require conversion to machine language before execution.
- A compiler or interpreter is used to translate 3GL code into machine language.
- A compiler converts the entire source program into machine language before executing it, producing an object code or object program.
- An interpreter translates and executes one statement at a time, without producing an object program.
- Compilers check the source program for errors and produce a program listing with errors, while interpreters do not produce an object program.
