Avg score: 82% Most missed: “A lot of code to do a job is called a _______.”

We have looked at examples of algorithms. Once you have your algorithm written down you have a simple plan. It has steps in it. But computers and robots cannot understand what you have written down. They only understand codes. These codes can be words, letters or numbers. They are like a special language. So you have to take each step in your algorithm and turn it into code. Codes make up units. Then we use these units when building scripts. Scripts can run programs. Programs have a lot of code to make a computer do a job.
