Short and simple: Scrypt is the algorithm used for encryption. Bitcoin uses SHA256 for encryption, not scrypt. So, scrypt mining is nothing other then mining coins that use scrypt encryption algorithm

Not really encryption.

For example, the sha256 output of your post is:

Code:

.

That is absolutely no way to "decrypt" it back to your post, because it is not an encrypted version of your post at all.

What would be the word for it, if it is not encryption?

It is hashing, or you can also call it one-way encryption. It's frequently used in password databases.
When you input a password, it is hashed with a hashing function, and the correct password isn't stored on the database: its hash is. Then it compares if the hashes are the same, if they are, you login, if they aren't you get a login error.

I see, that's a good noob-friendly way to explain it.
Thanks for your answer!

Hash / hashing.

Quote from: http://en.wikipedia.org/wiki/Hash_function

A hash function is any function that can be used to map data of arbitrary size to data of fixed size, with slight differences in input data producing very big differences in output data.

For your reference, "SHA" standards for "Secure Hash Algorithm"

On the other hand,

Quote from: http://en.wikipedia.org/wiki/Encryption

In cryptography, encryption is the process of encoding messages or information in such a way that only authorized parties can read it.

for a beginner and unless you have a solid budget Scrypt coins are not good to start with if you have a CGN compatible gpu or modern Nvidia go for X1X coins if not Scrypt-N is your only choice as the scrypt has become nowadays an asic playground

Also it is not asic proof algorithm as the sha256. Try to search for another algorithm coins.

This.
It also has the advantage of being more profitable to mine on GPUs, since there are less ASIC available.

However, this is becoming less and less true, and mining Scrypt-N or X11, which are yet other algorithms, would be more profitable to mine for regular users.
