What is an algorithm?

An algorithm is a set of step-by-step instructions that tells you exactly what to do to complete a task. A recipe for making a sandwich is an algorithm.

What is a sequence in computer science?

A sequence is a set of instructions carried out one after another in a specific order.. Socks, then shoes. Shoes first does not work. Order is the sequence.

Is this true? A loop is not an instruction that repeats the same steps over and over.

No. A loop is an instruction that repeats the same steps over and over. Instead of writing 'clap' five times, you can say 'repeat clap 5 times.' Loops save time.

What is debugging?

Debugging is finding and fixing mistakes in a set of instructions. A bug is an error that makes the instructions not work right. Fixing it is debugging.

What is an input?

An input is information or an action that goes into a device or system.. Tap a letter key. The tap going in is the input.

Is this true? An output is what a device gives back after receiving an input.

Yes. The letter that shows on the screen is the output.

What is a digital footprint?

What is online safety?

Online safety means protecting yourself when using the internet.. If something online feels weird, close it and tell a grown-up.

Match each prompt to its fact.
