Spot the advantage of a compiler:

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

Two low-level languages:

Assembly language and Machine code

Spot the advantage of an Interpreter

Can run on machines with different instruction sets.

Typical features of interpreters

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

Compiled code that can run on a machine specific device

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

Compiler
Interpreter
Assembly language
Binary

Can spot errors at compile time.
Produces a 'stand-alone' executable.
Provides an 'eval()' function and 'shell'
