Study Notes
Low-Level Languages
- Deal with a computer's hardware components
- Two common types are machine language and assembly language
Machine Language
- The language that a computer can directly understand
- No need for translation or compilation
High-Level Languages
- Use natural languages, such as English
- Require translation or compilation to execute
Compiler
- Translates a program written in a high-level language into a machine language
- Translates the entire program before executing the program statements
Interpreter
- Acts as a compiler, but translates one program statement at a time
- Executes the statement as soon as it is translated
Errors
Syntax Errors
- Errors encountered during the process of compilation
- Examples include misspelled commands
Logical Errors
- Errors when the syntax of the program is correct, but the expected output is not achieved
Algorithm
- Must be expressed completely in a natural language that anyone can follow
- Examples include directions written in English
