Programming Languages

1. IDE (Integrated Development Editor)

   • TREE
     • Translator
       • Translates the entire source code into machine code
       • Translates source code into machine code one line at a time.
       • Needed to either compile or interpret the source code so that the computer (CPU) can understand it.
       • Used to translate source code into machine code. A compiler and interpreter are both examples of this.
       • Assembler
         • Translates assembly code into machine code
     • Editor
       • Allows the end user to enter the program code. It can colour code keywords and may even autocomplete words as you type.
       • Colour codes words
       • Allows editing of code.
     • Error Diagnostics
       • Highlights errors in the code and may suggest possible solutions.
       • Syntax errors
     • Run Time Environment
       • Allows you to run and test your code when developing your program.
       • Allows user to check for logic errors
     • Compiler
       • A programming tool to translate source code into machine code
       • Translates source code into machine code all at once
       • Only needed once to create one executable file
       • Returns a list of errors for all of the program once compiling is complete
       • Once compilied the program runs quickly but compiling takes a long time.
     • Interpreter
       • Translates and runs the source code one instruction a t a time.
         • Does not create an executable file.
       • Needed every time you want to run the program.
       • Programs will run slower because the code is being translated as the program is running.

2. High Level and Low Level Languages

   • High Level- Source Code
     • Understood by Humans
       • Python, JavaScript and Scratch
     • Instructed by using words
     • Portable and can be used on other machines (computers).
     • Portable and can be used on other machines (computers)
   • Low Level- Machine Code(Binary), Assembly Language, Mnemonics
     • Understood by CPU
     • Machine code is the lowest-level programming language consisting of 0 and 1. CPU can process it as a string of instructions.
     • Assembly Language is low level code in mnemonics. An example of this is MOVF for move forward.
     • Specific to a paticular machine (computer)
