QuestionAnswer
Discuss the advatanges of using a high level language compared to a low levelProgram code is easier to understand/maintain/debug; Faster development time // programmers can be more productive // one line of HLL code can do the same job as many lines of assembly language; Programs are (more) portable (to other hardware platforms) Language is problem-oriented; More support/ better refined as more programmers use it; Support for different paradigms; A. Examples eg functional programming Built-in support for data structures; A. Example(s) eg arrays, records Availability of flow control structures; A. Example(s) eg loops, selection Improved features for supporting modularity; A. Ability to use subroutines
Discuss the disadvatages of using a high level language compared to a low level (Assembly language)Assembly language code may execute more quickly is because translation is not required Assembly language code may use less memory; Assembly language gives direct/better access to computer hardware // enables direct manipulation of memory (contents);

Explain the term ‘imperative high-level language’A programming language that requires programming discipline. Programmers must develop a proper order of actions in order to solve the problem. A 'procedural language' BETTER: (1) Instructions are executed in a programmer-defined order (1) High level language instructions use English-like keywords
