2. Pseudocode a notation resembling a simplified programming language, used in program design.
3. Machine Language a programming language designed for use on a specific class of computers.
4. High Level Computer Language an advanced computing language that are instructions in simple terms in a particular structure. (syntax) It is easily understood by both the computer and people.
5. Flowchart is a diagram of the sequence of operations in a computer program or an accounting system. Uses set symbols to describe an algorithm.
6. Sequence is the order in which the steps have to be carried out. it is important because
7. Selection where you make a choice between available options. A selection is present usually when the word 'if' is used. Most algorithms have selection included.
