high and low level language

Question 1

what is an adv of using high level language

Answer 1

it enables no knowledge of the hardware
they are portable so it can be used in different devices
it is close to human language so it is easier to understand
it is easier to correct errors

Question 2

give examples of high level language

Answer 2

JAVA, python

Question 3

adv of using low level language

Answer 3

fast and memory efficient
direct access to the processor
executes instructions faster

Question 4

how do low level languages work

Answer 4

they use assembly and machine code. They work directly on the CPU

Question 5

what is assembly language

Answer 5

they are low-level language that needs to be translated into machine code by the assembler

Question 6

what is machine code

Answer 6

binary instruction that a computer understands. It requires no translator

Question 7

what are compilers

Answer 7

they transfer the whole program at once
they create an ‘exe’ file so there is no need to recompile which allows faster execution
list of errors is created

Question 8

what are interpreters

Answer 8

they translate one line of code at a time
machine code is directly executed
identifies error as soon as it finds one and stops
error must be fixed in order to continue
easier to debug
