Classification of Programming languages

Question 1

Low level languages

Answer 1

are specific to the type of processor they are written for and directly affect computers processor
Machine & assembly code

Question 2

Machine Code

Answer 2

only uses the binary digits 1 and 0 to represent instructions
therefore very long and extremely difficult for humans to understand
difficult to debug
directly manipulates a computers processor
no need to translate therefore useful where speed of execution is important

Question 3

Assembly language

Answer 3

meant to simplify the process of writing computer programs
contains Mnemonics e.g. ADD and MOV
1 to 1 correlation to a machine code instruction

Question 4

High level languages

Answer 4

not processor specific but must be translated into machine code by compiler/interpreter before executed

Question 5

benefits of high level languages

Answer 5

use english instructions that make them much easier for humans to learn and understand + easier to debug
use built in functions

Question 6

Imperative vs Declarative

Answer 6

imperative high level languages tell a computer HOW they should complete a task
declarative describes WHAT a computer should do
