### What exactly is an algorithm?

An algorithm is a list of instructions and rules that a computer needs to complete a task.

Everything we do with a device has an algorithm in it. However, those of us who are not experts in mathematics and programming do not clearly understand the term "algorithm". There is a common joke that when programmers do not want to give an explanation about their work, they use the word "algorithm".

We probably hear the word algorithm often, even occasionally. But what does algorithm really mean?

### What is an algorithm?

An algorithm is a series of instructions, which are followed step by step to solve a task or problem. For example, the recipe for making one type of cake can also be considered as an algorithm.

In the case of computing, the computer is constantly instructed to perform a task through algorithms. An algorithm consists of a precise list of instructions, giving a clear outline of exactly how a task should be accomplished.

So the most accurate definition of an algorithm is a small manual with instructions on how the computer will perform a task or how to analyze the data.

### How do computer algorithms work?

Computer algorithms work through inputs and outputs. The computer takes the data input and applies each instruction of the algorithm to that data to generate the output.

For example, a search engine is a type of algorithm that takes a search query as input and searches its database for information related to the words in the query. Then gives the search result output.

The algorithm can also be imagined as a flowchart. So that the input given in the initial way leads to some steps and questions, which have to be managed sequentially. The output is the result that is generated after each section of the flowchart is completed.

### Algorithms and automation

So far the matter seems straightforward enough. The question may still be asked, what is the algorithm used for? The answer is, it has many uses.

Algorithms are used in all fields of IT and computing. Algorithms can manage and process data. It can also do computing in a variety of ways.

A great example of an active algorithm is automation software. This is because in automation software, some pre-determined rules are followed to complete a task. These rules are actually algorithms.

Thus, automation software consists of a combination of many algorithms, through which various processes of work are automated.

For example, suppose for an automated task your automation software needs to take all the billing information received via email and put it in a spreadsheet. That's why you set some terms and conditions for that software program. These terms and conditions are actually algorithms.

In this example the input is each incoming email. Each of these emails is then placed within certain steps or rules to get the job done. This may include scanning or checking each email for the desired information. Emails that contain this desired information move on to the next step and continue to follow each step to identify and extract relevant data. The output here is the information that is kept in the spreadsheet.

In short, an algorithm is a blueprint for a work plan that outlines the main way to accomplish that task. An algorithm in computing is a list of some of the instructions and rules that a computer needs to perform a task.
