Languages and Enviroments

1. Difrrent Levels of Languages

   • Low Level Languages
     • Low Level langugaes are languages that are simplistic and simmilar to a CPUs architecture details.
     • Low level languages are hard for humans to understand and hard to write / edit
     • E.g. Binary / 100101010
     • They can be directly executable by a CPU, or require little translatting, i.e. they are easy for the computer to understand.
   • High Level Languages
     • High level languages are languages that are more complex and closer to the human language than their low level counterparts
     • They cannot be executed directly by the CPU. They need to be transleted into machine code I.e. Binary, a low level language
     • High level languages are closer to natural language, and are easier for humans to understand, write, and edit
     • E.g Python

2. Diffrent Types of Languages

   • Procedual Languages
     • Procedural Languages have a clear start and end point, and they follow a set pathway.
     • They are popular and used by many programmers
     • e.g. Python
   • Object Orientated Languages
     • Object Orientated languages create specific objects
     • These objects contain information about a subject and are represented by classes
     • Object Orienatated languages are often used for complex programs
   • Declarative Languages
     • Declarative programs consist of a collection of facts and rules
     • Not every soloution is accounted for. Instead, the program uses the information it is given, as wella s the facts and rules it has stored, to create an individual response
     • Declarative languages are useful in situations involivng fuzzy logic
     • e.g. Used in Artifical Intelligence and software like WebMD
