Introduction to programming

In the first sessions of our new Unit, Programming, we have used (or will use) several interesting websites. The information you learn from them will always be accesible for your through these links:

Here you can understand how different daily life machines need programs.

Programming = coding
Programming is telling your computer what we want it to do for us. A computer can do anything we want...


But we need to give instructions to it in the appropriate language. You can watch this video to understand it better (only until minute 1:30).

The language we use to communicate to the computer is called programming language.  For example: Javascript, Scratch, C++, html.


What is a program? Watch this video to find out.
A program is a sequence of actions for a computer to do something for us.

How to represent a program

In our last class we learned that programs are sequences of instructions to perform a task within a computer.

To represent those sequences, we use a type of diagram which is called FLOW DIAGRAM.

So, a flow diagram is a graphic representation of a sequence.

Flow diagrams use a group of symbols that we need to learn in order to represent them correctly:

Here is a series of exercises to practice flow diagram design:

And remember... there can be a flow chart to solve almost every problem on Earth!!!
