I might be repeating what the book said, but the way I understand the word is that, say if you use a function again and again it will not make any permanet change to data.

for example in a Post Method you are going to do something to the data that was submitted by the user there for it is not idempotent. But in a Get Method you are only "getting" data to display to the user with out changing it there-for the get Method is idempotent

hope this helps
good luck

Nestor, I am a 46 year old native speaker of English (I am English) and I had never heard the term Idempotent untill about 3 months ago, so don't worry about your English ..

I don't think it is a big deal on the exam.

Idempotent is a mathematical term. It Means The Same Result. Unchanged Result.

For example.
1. 120*1=120
2. 123/100*100=123

In terms of Computer, Unchanged Result.
1. For get request. Usually result is same.
2. If we have two buttons And for both buttons the code is same then the result if we click any button will be same.

Nestor, I'm brazilian and I'll try to answer you in "Portunhol" (Portuguese+Spanish)

idempotence es quando usted puede repetir mutchas vezes a mesma operacion e tiene o mesmo resultado.

Pense en una busca no google. �s un GET request, e tu puedes repeti-lo mutchas vezes com o mesmo resultado porque esto no cambia los dados del server.
Un POST request �s para tu enviar dados para el server, como en una operacion de e-commerce. No puedes repeti-la despues... Entendeu?

(My spanish sucks, but I hope I had helped)

I had always assumed that there was very little in common between Spanish and Portuguese, was I wrong?

In fact Portuguese and Spanish have the same "parent". I'd say they extend the same "father", Latin.
For portuguese speakers is quite easy to understand an learn spanish, just like the opposite.
Of course they have their differences, but the "root" is the same... Entendeu? (got it? )
