Compiled code that can run on a machine specific device

Spot the advantage of a compiler:

Once code has been compiled you no longer need the source.

Spot the advantage of an Interpreter

Can run on machines with different instruction sets.

Two low-level languages:

Assembly language and Machine code

Typical features of interpreters

Provides an 'eval()' function and 'shell'

3
Spot the advantage of a compiler:
It is easier to spot logical errors in your source code
The program can run on different interpreters.
whenever you make an alteration to the code you recompile
Once code has been compiled you no longer need the source.
4

6
Spot the advantage of an Interpreter
The source code must be distributed to users.
Source code is compiled very rapidly.
Can run on machines with different instruction sets.
The source code is hidden from the users.
7

11
Typical features of interpreters
Can spot logical errors at compile time.
Provides an 'eval()' function and 'shell'
Can spot errors at compile time.
Produces a 'stand-alone' executable.
