What is EVM | EVM full form

You must have heard the name of EVM (Electronic Voting Machine) EVM. Because EVM remains in discussion for one reason or the other. Especially when the Lok Sabha elections are held, because EVMs are used in that. And the rest of the other low level elections are done from ballet paper. So today we will know what is EVM. And after all, what is the reason that EVM remains in the discussion even after the elections. What is EVM?

Because you must have often heard that EVM has been hacked. So today we will get complete information about EVM. Because the Lok Sabha election is an important election. And why low level elections with ballet paper. And why the Lok Sabha elections are conducted with EVMs.

What is EVM

The full form of EVM is electronic voting machine. As you know that due to technology all the tasks have become much easier. Then whether it is in any industry. Then whether it is a company or a general purpose task.

In the same way, EVM is also an electronic device for voting. Because of which the voting of the Lok Sabha takes place. The way the local polling is done, like that of the village head, district panchayat etc., in the same way the voting of the Lok Sabha is also done. But this is a huge election, which if done with ballet paper, will take more time and money. Whereas EVM saves all these things.

Because when there are low level elections, a ballet paper is given to the voter. On which the names and marks of all the candidates are there. And the voter puts the ballet paper in the box after stamping it with the mark of the person he wants to vote for. And after a few days, which is counted manually. And the result is announced.

And the Lok Sabha elections have also been held with ballet paper many times. But elections with EVMs are faster than ballet paper voting. It also reduces the cost as voting has to be done through EVM. So there is no need of any ballet paper. And also there is no need for any manual process for counting. Because EVM does autocount.

EVM is a combination of two different units. One of which is the ballet unit, the way voters are given ballet paper for normal voting. EVM machine has a ballet unit in its place through which voters vote.

And the second is the control unit, which is near the election officer, a little far from the ballet unit. And both the units are connected to each other. Because only the ballet unit alone cannot do anything. And not just any one unit is called EVM. Rather, both the units together are called a complete EVM.

EVM Ballot Unit

The name and symbol of the party/candidate of all the candidates are present in a straight line on the ballet unit. And there is a button right in front of all of them. Through which the voter casts his vote.

The party/candidate the voter wants to vote for. One can vote by pressing the button in front of his mark/name. But the button can be pressed only once at a time. Then it may be any button because after pressing once the EVM gets locked. The advantage of which is that no voter can give multiple votes even if he wants to.

EVM Control Unit

The EVM control unit is near the booth election officer a few meters away from the ballet unit and when a voter casts his vote. And if the EVM gets locked, then the voter another voter comes forward to vote. And it is released by the officer control unit, so that the next voter can vote.

Yes, it is very important for the EVM to be locked after every vote, otherwise many voters could press a button multiple times. Due to which the voting becomes wrong, due to this the locking feature has also been provided in the EVM. So that no person can give multiple votes.


Many boxes are needed for voting by ballet, due to which additional vehicles are needed for portability. And many rooms are also needed to keep them.

But EVM is a very small machine. Which is very easy to carry from one place to another.

ease of counting

Due to EVM, counting is also done very easily. Whereas if voting is done with ballet paper then the votes have to be counted manually. But EVM is an electronic device which automatically counts all the votes. Due to which no extra special team is required for counting.


Since EVM is an electronic device, security is very important, it is very important for EVM to be hard coded. So that no interference can be done in EVM.

And all electronic devices such as phone, computer, tablet, EVM, etc. are a combination of hardware and software. And it is necessary for both to be strong.

If the hardware is weak then the EVM can get damaged anytime. And if there are bugs in the programming then it can be interfered with. But EVM is not used online. That’s why there is mostly no risk of hacking or any type of attack.

And EVM manufacturer says that EVM is completely locked. Once the EVM is ready for use, even the manufacturing company of EVM itself cannot interfere in it. Because in the last stage of programming of EVM it is locked.

And then no one can interfere in EVM, yes there may be many bugs in EVM. Because no programming program is 100% perfect in the initial stage. But to make it better, continuous improvement has to be done in it, which also applies to EVM.

As the company says that after the EVM is ready, no one can interfere in it. Even if it is the company itself, no other person can get EVM. Because all the tasks related to EVM are done under strict supervision.

However, it is difficult to say how safe EVM is because EVMs are often accused. And election commission and EVM developer company claim that EVM is hack proof.

However, we do not claim whether EVM is safe or not. Just we are giving you basic information about EVM. That is, what is the full form of EVM. Because everyone votes. But very few people have an idea about EVM that what is EVM.

Why EVM is a better way to vote than ballot paper

Because there is no need to carry heavy boxes because of the EVM machine. And many votes are possible in a single EVM machine and there is a lot of ease in counting.
