What is algorithm? Definition & Usage of Algorithm

What is Algorithm: Dear Readers, you may have noticed from looking at the title of our article today that the topic of our discussion today is "What is Algorithm or what is it", "What is meant by Algorithm", "Features of Algorithm" and "Definition & Usage of Algorithm".

What is algorithm
What is an algorithm? Definition & Usage of Algorithm

You may have heard the name algorithm in modern times,

But even if everyone has heard the name, I wouldn't be wrong to say that most people have no idea what this algorithm really is.

Every day since we wake up in the morning we do different things. And in order to do any work, we have to follow some steps from beginning to end.

Work is a problem for us, and by working we solve any problem. In order to solve the problem through work, we set some order. Let me illustrate the point with an example,

Suppose you are asked to make tea, now you have to follow some steps or a sequence to make tea.

That way, if you are making rice, you still need to complete the task in a few steps or as a sequence.

What we need to do to make tea -

  • First of all, take water in a pot and heat it.
  • Now pour tea powder, sugar, and milk into the water.
  • Wait until the tea is boiling.
  • Now turn off the gas and pour the tea made from the pot into the glass or cup.
  • Now you can eat the prepared tea.

We can understand the above example as an algorithm.

Because, some important steps or a sequence has been followed in the process of making tea, and if this sequence is reversed, tea cannot be made.

By now you may have guessed what this algorithm really is. Let us know in detail below what the algorithm is.

What is an algorithm?

In the case of computer work, computer programs are written.

In these computer programs, we write different types of steps that a computer can do certain tasks by following.

When you give a task to a computer, you also have to think about how the computer can do the tasks you give it.

And that's why we use computer algorithms.

Simply put, an algorithm is a set or set of specific instructions by which a particular problem can be solved.

Definition of Algorithm

An algorithm is a step-by-step process or a formula by which a problem can be solved. It is basically a procedure where there are some limited rules which are called instructions.

Each rule or instruction is written one after the other and each rule (steps) is made for the purpose of performing some special operation.

And by following every rule in the right way, the solution to the problem can be found in the end.

Simply put, it is possible to find a solution to the problem as a result of these rules. So if we try to understand the algorithm in a very simple way, then

"Algorithm is a step by step process to solve any problem or problem.Now to put it more simply,

The algorithm has some steps where each step is designed for a particular operation. It starts with a step and ends with a single step through which the work is completed.

And between these two steps, there are other different steps that again do different things.

So hopefully, what does algorithm mean or what does algorithm mean? You must have got the answer to this question.

Use/importance of algorithms

Thus algorithms are widely used in programming. Basically, algorithms are widely used in the IT industry, business models, programming, etc.

Let us know in detail below, how and in what places they are used.

Computer Programming

In the case of computer programming, its algorithm is written before writing a program.

If any program starts writing without thinking, then there is a possibility of making a lot of mistakes.

So, if you can create an algorithm before creating the program, then the errors can be reduced.


The algorithm is written even before making a flowchart. If so, the chances of making a mistake can be greatly increased.

Computer Scientist and Software Engineer

Computer Scientists and Software Engineers, of course, use different algorithmsIts use saves them time and greatly reduces labor.

Suppose now there is a software company that was asked to create an app for a bank.

Now, this is a problem for the software company or software engineer which can be solved step by step.

If there are any mistakes or problems then it is possible to fix them there. And so, there are many benefits to developing the application.

Mathematical Problem Solve

It is used to solve mathematical problems. For example, if you want to know if a number is -ve or + ve?

In this case, you can tell by looking at the - and + signs. You know, but how can a computer understand this?

And for that, you have to write an algorithm.

If any number is greater than 0 then it is + ve Number and if any number is less than 0 then that number will be –ve number.

AI, space research

It is widely used in AI, space research, robotics, etc.

Features of the algorithm

We have discussed that the algorithm is a step-by-step process. Let's talk about the features of this algorithm.

  1. Undoubtedly - the algorithms you write require a few minutes of specific steps or lines.
  2.  Limitations - Each algorithm has to go through some finite steps. RTT steps have to be repeated in a limited amount.
  3. Input - 0 in each algorithm which may be a more accurate step from 0.
  4. Output - The algorithm needs an output step, just like the input step. However, the output must be the output for which we have algorithmic.
  5. Efficacy - Efficacy can be estimated through time and space. If the algorithm is written in less time and space or is less executed and runs in less space, it will be called the effectiveness.
