  1. Level 4 Software Design and Development Translator Programs

  2. High Level Programming Languages • When you have been writing your programs you either used graphical building blocks (Scratch) or you entered your program as text (Visual Basic). • Both of the above are examples of High Level Languages.

  3. Translators • As you already know a computer is a digital machine which means it only understands binary i.e. machine code. • Therefore programs written in a high level language needs to be translated before they are executed (run). • There are two type of translator; a compiler and an interpreter.

  4. Differences • Click on the link below and watch both the video and the animation about Compilers and Interpreters. • http://www.jhigh.co.uk/ComputingSG/SystemsSoftware/SSoft_Translation.html • Watch it as often as you need and make short notes so you can participate fully in the next lesson.
