There is no more difference between captcha code and recaptcha code, both are nearly similar but there is little bit difference between Captcha code and reCaptcha code. Both are used to keep our site safe and protected. So, now Let's know about captcha code.

What is the captcha code:

                          Captcha is the short form of Completely Automated Public Turing test to tell Computer Human Apart. The CAPTCHA code was first invented in 1997. At first Yahoo company used the captcha code. Earlier when the captcha code was not available, Hackers where doing spam to crash someone else sites or to increase the huge traffic on his site.

Hackers made the robot and through the robot they were doing too much spam. They created the huge amount of accounts in a second or in a minute through the help of that Robert or spamming method. In such a situation there was a confusion between human and robot. The site owner couldn't find out who is Robert and who is human.

To prevent such a kind of spamming captcha code was created. In captcha code the company set so many sloping or splay type of word. And they set some background noise or sloping lines because of that computer cannot scan that exact letter.

Captcha code prevented enough spasming because robot or computer cannot scan that type of word or robot can't read it, only a human can read that word. Sometimes human also cannot read that types of word. That's why there is a refresh option besides of every captcha code.

When human cannot understand the captcha code, then they click on refresh button and they get a new captcha code which a human can read.

  At first some numeric or some alphabetical later were shown in captcha code.Then captcha company design and they started to showing some difficult word.

Captcha company scanned all the Books and they find out which word computer cannot scan. And the word computer cannot scan that word set for captcha code.

In 2009 when Google came they also faced this type of spamming problem and then Google bought captcha code company. Then people were tiring of repeatedly fill up the captcha code.

Google Keep all these problems in mind and Google thought to make it easier. Before Google will do anything, in the market so many captcha fill up companies were established. Captcha fill up  company solved  all that captcha.

Then Google bring No captcha. In No captcha we have to tick or mark on I'm not a robot option. Then Google will give you the permission to enter on that site. Now the questions comes in your mind if we can mark on I'm not a robot option then why robot cannot mark on I'm not a robot option?

The answer is yes robot can also mark on I'm not a robot option but when you Mark on I'm not a robot option, then your IP address location and your activity or behaviour everything will go the Google. Even your cursor and fingerprint will go to the Google. Then Google can easily verify through your fingerprint or your movement of cursor.

If Google thinks 95% you are a human, then it will allow to enter on that site otherwise it will show you the captcha code or recaptcha code. Google will show you some images. The images will may be the bus images, car images, Traffic signals, etc.

So you have to identify that image and verify it. Then you can enter on that site.

It is called the No captcha because in No captcha we do not have to fill up any captcha code just we have to tick or select the images and we have to verify it. So due to the captcha code most of the spamming is prevented.
If you are providing a sign up option on your website, then I will recommend you to set the captcha code on your website otherwise and hackers will try to spam on your site, then maybe it will be crashed.
