   • Software
     • Languages
       • High Level
         • An advance language that can be 'read' as it resembles human language
         • Uses interpreters and compilers to convert
         • Slow to execute but easy to code
         • Examples
           • Anything else
       • Low Level
         • Written in a style that doesn't look like human language
         • Uses an assembler to convert to machine code
         • Very quick to execute
         • Examples
           • Engine control systems
     • Error Types
       • Linking
         • Occurs if a referenced file cant be found
       • Runtime
         • A error with the code that isn't found during analysis like 0/0
       • Logical
         • The program runs to completion but doesn't give the expected result
       • Rounding
         • When details are lost due to rounding
       • Truncation
         • Occurs when data is shortened
     • Stages of compilation
       • Lexical Analysis
         • Symbol table analysis
           • Syntax Analysis
