2.5 Translators and IDEs V2

1. Machine Code

   • An instruction that can run inside the CPU is called machine code and is in binary.
   • Very hard to code in, and very time consuming

2. Assembly Language

   • Low level language, because it's almost the same as machine code
   • The complete set of commands is called the instruction set of the CPU
   • Consists of a set of mnemonic instructions

3. High Level Language

   • Has a set of keywords such as PRINT of IF
   • It has a set of grammar rules called syntax
   • Programmers write source code

4. Translators

   • Converts programming language into machine code
   • Three types: Assembler, Compiler and Interpreter

5. Assemblers

   • Convert assembly code into machine code
   • Different CPUs will need different assemblers
   • difficult to write in but still easier than machine code
   • used in fast execution
     • required when there is limited memory or file size

6. Compliers

   • Converts all source code into machine language
     • in one go
   • Outputs an executable program
   • error reports created with object code

7. IDE

   • Brings all the tools necessary to code into one application
   • Tools in the IDE are: Project manager, code editor, run-time environment, debugger and translator
   • integrated development environment

8. Interpreters

   • translate and execute source code, and execute line by line
   • Lot slower than complier
   • checked for syntax errors
   • if incorrect the interpreting is stopped
