Start event symbol signals the first step of a process. Process is a series of actions or steps taken in order to achieve a particular end. Decision is the action or process of deciding something or of resolving a question. End event symbol stands for the result of a process.
Algorithms and flowcharts are two different ways of presenting the process of solving a problem. Algorithms consist of a set of steps for solving a particular problem, while in flowcharts, those steps are usually displayed in shapes and process boxes with arrows. So flowcharts can be used for presenting algorithms.
The diamond symbolizes that a decision needs to be made. If there are only two choices, you can draw arrows directly from the diamond to the next step (example on the left). If there are more than two choices, you can draw them neatly by copying the example on the right.
