- 1programs written in a high level language need to be translated because?computers can only understand machine code (binary)
- 2there are many different types of high level programming languages becausehigh level languages are often written to solve particular types of problems
- 3what is machine codebinary numbers, 1 or 0
- 4what is a low level languagelanguage used to directly control a computer
- 5one reason for low level programming languages being badit is not easy for humans to read or understand
- 6what is one property of a high level languagethey need to be translated into machine code so computers can understand it
- 7what is a natural languagea natural language is just communicating to a computer in plain English
- 8what is a syntax erroran error due to the fact that the syntax of the language is not respected
- 9what is a semantic erroran error due to an improper use of program statements

- 15what is a declarative languagea declarative language is one based on a set of rules instead of a set of predefined procedures, it is most commonly associated with AI programming and development.
