Chronology 1: Algorithm

Book Version:
In computing, algorithms provide computers with a successive guide to completing actions. They’re comprised of a precise list of instructions that outline exactly how to complete a task.

Use with Explanation:
In essence, algorithms are simply a series of instructions that are followed, step by step, to do something useful or solve a problem. You could consider a tea recipe an algorithm for making a tea, for example.

How do computer algorithms work?
Computer algorithms work via input and output. They take the input and apply each step of the algorithm to that information to generate an output.

For example, a search engine is an algorithm that takes a search query as an input and searches its database for items relevant to the words in the query. It then outputs the results.

You can easily visualize algorithms as a flowchart. The input leads to steps and questions that need handling in order. When each section of the flowchart is completed, the generated result is the output.
