| Discuss the advatanges of using a high level language compared to a low level | Program 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); |
| Which type of programming
language is this?

01001011
10110110 | Machine Code |
| Which are processor specific: low-level
languages or high-level languages? | Low-level languages |
| Which type of language uses
mnemonics in instructions? | Assembly language |
| Which type of languages must be
translated into machine code with a
compiler or interpreter before execution? | High-level languages |
| What are the two types of low level langauge? | Machine code
Assembly language |
| Describe machine code langauage | Programming with the use of numerical characters |
| Describe assembly langauage | Programming with the use of mnemonic characters |
| 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 |
