Algorithm

What is an Algorithm?

• A chart showing the flow of a series of events
• Step-by-step instructions used to solve a problem
• A decision arrived at by following instructions
• A computer program that follows a chart

What is a flowchart?

• A text-based way of designing an algorithm
• A specific programming language
• A diagram that represents a set of instructions
• A bullet point list of instructions

What algorithm do we use when we're looking for the Post Office?

• A set of directions
• A recipe
• A list of instructions

Programming languages give computers instructions

• True
• False

What algorithm do we use when we're building a wardrobe?

• A set of directions
• A recipe
• A list of instructions

We can show the sequence of steps in an algorithm in a structural diagram called a flow chart.

• True
• False

Only top software programmers can write an algorithm.

• True
• False

What should be considered when designing an algorithm?

• If the correct hardware is being used
• If the correct software is being used
• If there is more than one way of solving the problem

When can algorithms be used?

• Only with computers
• Only when programming
• Only with flowcharts
• Any time to design solutions to problems

An algorithm ...

• ... illustrates some steps, in no particular order, and following no logical reasoning
• ... illustrates a series steps in a particular order, following logical reasoning
• ... illustrates some random shapes in a flowchart but in a set order
• ... illustrates series of decisions needed to bake a cake
