What is flowchart and how to create?

Do you know what Flowchart is and how to use Flowchart Symbol. If you do not know, then there is no need to be disturbed. In today's article, we will discuss about it.

Every day we get up at work as soon as we wake up in the morning. Follow each step from start to finish till every task. Every work is a problem for you and the solution to the problem is found by working. To solve, we set a sequence. Let's understand with an example, "You have to make tea", then to complete this work, you need to follow some steps. like

First put water in a vessel and heat it.
Add tea pati, sugar and milk to the water.
Wait till the tea boils.
Turn off the gas and sieve the tea.
Tea is ready, you can have it now.
You must have realized by this that we do all the work of daily life in this way. So these steps are called Algorithm in computer language. It is mostly used in Software and Business Industries. When the algorithm is created, these steps are then shown through Flowchart. Which makes it easier for the programmer to understand the problem. Now without delay, know what is flowchart and how it is made. You will also learn how it has made your work easier.

Nowadays everyone has a little knowledge about programming. Through programming we can make software and a software helps to remove the problems of our life. But everyone has difficulty in writing programming, so we use flowchart and Algorithm. Through flowchart, we can show any program to people through Symbols, which will be easy to understand.

Flowchart is a tool created by Program Industry. Shows the steps used to solve a process or problem. We have to use some symbols to make a flowchart. Such as Square, Rectangle, Dimond, Oval, Arrow.

All signs have their own different significance or meaning. We cannot change the meaning of any symbol by ourselves. All signs are joined with an arrow. Through this arrow we get to know in which direction or flow order the flowchart is going. Now we should understand the meaning of different signs and know where it is used.

Some symbols used in Flowchart are (Flowchart Symbols)
Flowchart is a graphical image. Which shows the steps of a process. That is why you must know what these signs mean. And where to use them properly.

Start / End
This symbol is used to start and finish the flowchart. The words stop / end are used to start and finish to begin.

Flow Lines (Arrow)
We use this arrow to know in which direction or in which order the flowchart is going. When we take an example, you will easily understand.

Input / Output
We use this symbol for input and output. The output of the program is there and we show it using this symbol. Like we have to add two numbers, first of all we need to take the input of both the numbers. For this, after adding the Input Symbol, the Output symbol is used to show the addition.

Process
We use this symbol to process the same data that we input. This sign is used when calculating something means when calculating something. Just like adding, subtracting, multiplying and dividing a number, this symbol is used only.

Decision (Dimond)
When a condition has to be shown, then we use this symbol. The answer comes in the form of 'right' and 'wrong' or '0' and '1'. For example, to find out whether a number is Positive or Negetive, we need to Comparision both Numbers. EX- 4> 0 (Is it greater than 4?) The answer is one of "yes and no". Dimond Symbol is used in this.

We will take an example to know the use of all symbols
Rules for making flowchart
There are some rules for making flowchart as well, using which we can easily make flowchart and we will also have easy understanding. Some rules are-

All the symbols that are used while creating a flowchart, all the symbols are added by the arrow, so that we know in which direction the flowchart is going.
All flowchart is a starting and ending point.
When we use some condition in flowchart, it has 2 exit point. Is upward, downward or side, which has 2 outputs - first right and second wrong.
Subroutines have their own flowchart.
The end of each flowchart should be symbolic.

What is UPS and how does it work?

Do you know what is UPS? Why is it used and what are the types? If you are a computer user, then you probably already know about UPS because it is used in most computers. But even if there is no complete information, there is no need to panic because in today's article we will try to provide information in the context of what is UPS. During our daily work, we go through a state of power cut in a lot of time. By the way, other electrical appliances of the house like Fan, Light, TV, Fridge are not affected much because they do not need continuous power supply, but if you have a computer system, then it is necessary to use it properly. There is always a need for continuous power, in such a situation that if there is a Power Cut, then there is also the risk of our data loss. Just to overcome this problem, we need a device that can provide us with interruption free power supply. This type of device is called UPS. This UPS or uninterruptible power supply (UPS) is a device that continuous...

5 technologies that can completely change Indian agriculture

With 18% of GDP, agriculture has always been the most prominent sector of the Indian economy. Additionally, India has emerged as the world's largest producer of wheat, rice, pulses, spices and many products. The Government of India is coming up with new initiatives and agricultural programs to improve the agriculture sector and create better routes for rural development. However, most Indian farmers are still not aware of advanced agricultural technologies due to unavailability of valuable information and necessary resources. Information technology (IT) plays an important role in farming. Innovative development in the IT sector can help farmers to produce higher crop yields and better quality. In this post, I will talk about some advanced agricultural technologies that can completely transform Indian agriculture: Although biotechnology is not a new technology, it is an essential tool in which more possibilities have not been revealed yet. Whereas it empowers farmers to produce more...

What is Virtual Reality and how does it work?

Do you know what Virtual Reality is? How is this different from the original reality? What are its different types? If you want to get information about all these things, then you will have to read the complete post What is Virtual Reality. Have you ever been to Mars, ever swam with dolphins, or been busy with some dinosours. How would you feel when I tell you that you can still do all these things, in the same way as if you are present in that place at that time. Through Virtual Reality we can resurrect real reality. If you want to know more about it then please stay with us. Virtual Reality is an artificial environment that has been created with the help of software and some special hardwares. So that the user gets that artificial environment completely real. In a computer, we experience this virtual reality with only our two senses, they are sight and sound. Virtual reality means creating a world that is imaginary all of its own but appears to be completely real. For this, high-perf...
