QUICK AND DIRTY RECORDING TERMS:
AUDIO INTERFACE (Often called an "External Sound Card"
-Typically, these are external little boxes, some look like mixers. Some have one input, some have many. Most connect via USB, firewire etc. Some Audio Interfaces require internal PCI cards as well as external expansion boxes. Pro Tools rigs at the high end are a good example. They have internal "daughter cards" and external Input output boxes. But for most folks, recording at home, on a budget. you are looking at a USB/Firewire connected box with one ore more inputs.
The scarlett is a good example. I know that language itself is sometimes a barrier and that there is a lot of info to track here. So I thought it might help to spell this out a bit?

Now if you want to record directly in to your laptop (most of GMC students I"ve spoken with tend to record on laptops but certainly not all. Some use Towers. Most use PC's but some use Macs.) You typically have a MIC LEVEL INPUT that looks like a small headphone jack. MIC LEVEL inputs are different than LINE LEVEL inputs. Here is a

This can often sound quite bad unless you take some steps. As you are bypassing a speaker cab, you usually have to fake it. Either with speaker emulation of some type, or in software.
BACK TO THE DIRECT BOX
If you are recording directly in to your machine, the DI BOX alone, probably isn't worth doing IMHO. But if you are going to use some sort of hardware emulation (LIKE THE SPIFFY BEHRINGER DI WITH EMULATION) you may be able to skip the amplitude plugins altogether if you like. This box acts like an amp/speaker etc. It's more about being a SANSAMP type unit than about being an direct box when used like this.
So then we have
HARDWARE EMULATION
-LIke the SANSAMP, or this new BEHRINGER DI, that let you sound like you are playing through a full amp/rig, without needing one. You can record direct to computer, or use an audio interface.
SOFTWARE EMULATION
-Like Amplitude and such. These let you plug either direclty in or through an audio interface and sound like a full amp/rig without needing one using software running in your computer.
RECORDING AN ACTUAL AMP
-Here is where new recordists run in to trouble. They may take the headphone output, or line output of their fav practice amp/stack etc. and run that in to their computer/laptop or in to their audio interface. The results can be quite crap.
Unless the amp has 'speaker simulation" the signal isn't going to sound right as it's not getting "speaker color" it's not going through a speaker.
*The best way to record a real, live, honest to God amp. Is with a real, live honest to Microphone. Usually an SM57 is a good place to start,

Not the least of which is lack of isolation (unless you put your stack in the living room and have your mix position in the bedroom) and neighbors. Bringing us back to emulation.
FULL CIRCLE!Hopefully this lays it out in basic terms and gets you over some of the initial problems / issues of being a new home recordist. It's frustrating at first. Just like playing guitar. But it gets way better the more you do it. And it's no good in a vacuum. So share your recordings and be open to criticism. Also, taking criticism well requires practice.
