Languages & Environments

You should be able to describe the key characteristics of the following language types:

1. 
   Low-level languages
   
2. 
   High-level languages
   
3. 
   Procedural languages
   
4. 
   Declarative languages
   
5. 
   Object-orientated languages
   

All processors understand data in binary form only. The value 180 is represented and processed in binary as: 10110100.

Why is 10110100 the binary representation of 180?

Creating binary code for every instruction would be time consuming and require a lot of concentration. One slight error could send the wrong instruction to the processor.

Programmers realised that they had to develop low-level languages that were easier for humans to use but that could be converted into binary efficiently.

The two common low-level languages are and machine code assembly code.
