Flow-Chart

Flow-Charts are a key part to creating a code. Flow-Charts show the function that the computer is using. Flow-Charts are a necessary part to a computers thought process. If this chart is not being used then the computer will take longer and possibly not even load. The key parts in a flow chart are the start, the end,the process and the decision.

In flowcharts, different symbols are used to represent different parts of a process. These include : Start, Process, Decision and End. The Start and End symbol are self explanatory as it is the beginning of the sequence or the end of one, the process symbol will tell you when something happens such as "Wait 1 minute" or "Place knife on counter", The Decision symbol can be used for making a decision on a true or false decision or possibly the amount of something eg. slices of bread or how much money you need.

The Input-Process-Output Model

Input - Represents flow of data from outside the system.

Process - Includes all tasks required to affect the transformation.

Storage - Keeps the data until it is needed.

Output - Where the data and information flow out of the transformation process.

An example sequence that uses this model follows :

Input Process Output

Two Numbers Add first number to second number New Number

Another Flowchart example that uses alot of different decisions and processes can be a sequence to make some cheese of toast. Example of this work shows below. This is an example task from the Computer Science textbooks.
