Algorithms
Good notes will help you organise and process data and information
Note taking is a way of helping you to remember things you would otherwise forget. It also stimulates our critical thinking skills.
Remember! whenever you see the notes icon in a video this means the information is important and you should write it down.
An algorithm is a sequence of steps used to solve a problem
To get a computer to do something we have to tell it what to do. We do this by using a set of instructions. These instructions are called algorithms.
An algorithm has a defined outcome – a defined end. Algorithms can be written in many different ways. Each way has a different cost, different speed and requires different external hardware.
You are creating an algorithm every time you write a program. You are creating a set of steps to perform a task. Before we create a computer program we write it out in one of two ways.
1. As a set of intructions like a recipe.
2. As a flowchart.
area= width x length. display "what is the room's width?". input width. display "what is the room's length?". input length. display area.
Lets look at the learning outcomes and decide which one best describes our current level of understanding :
