High level vs Low level programming languages
  1. High-level programming language
    1. Procedural programming
      1. Instructions are given in sequence
        1. Selection is used to decide what a program does
          1. Iteration dictates how many times it does it
            1. Programs are broken down into key blocks called procedures and functions
              1. BASIC, C and Pascal
            2. Object-oriented programming
              1. Solution consists of objects that interact with each other
                1. Java and C++
                2. Designed to be closer to the way we express ourselves
                  1. Using a mixture of English words and mathematical expressions
                  2. Can be converted to machine code
                  3. Low-level language
                    1. Assembly language
                      1. Mnemonics used in place of machine-code instructions
                        1. Mnemonics (memorable letter sequence)
                        2. The set of instructions varies from processor to processor
                          1. Assembly code written for one processor may not necessarily work on another
                        3. Directly linked to the architecture of the computer
                          1. Machine code
                            1. Uses binary to represent instructions (opcode)
                              1. On data which the act (operands)
                              2. Rather than remembering which binary code represents which instruction
                                1. Assembly code use mnemonics to represent the sequences
                                  1. Each assembly code instruction represents a machine- code instruction
                                    1. Assembly code programs can be longer than high-level equivilents
