Convert programming languages into machine code as only understand this to execute instructions |
|
|

|
|
What are the characteristics of a compiler? |
-Translate all source code at same and creates one executable file -Only needed once to create executable file -Returns a list of errors for the entire program once compiling is complete -Once compiled, the program runs quickly but compiling takes a long time |
|
|
What are the characteristics of an interpreter? |
-Translates and runs the source code one instruction at a time but doesn’t create an executable file -Needed every time you want to run the program -When finds its first error, it stops -Programs rub slowly as code is being translated as program is running |

|
|
What are the characteristics of low level language? |
-More tricky for humans to understand but easier for computer to run -One instruction of low level language represents one instruction of machine code -difficult to understand -Written for one type of machine |
