I'll type up a vocab for you in a sec.
Ok here you go Calender.
Compiler: Computers read 1's and 0's, binary code. A compiler converts human language into binary through the use of coding languages such as C++, C#, and a stuff load of other languages that I've probably never heard of.
Explorer: Most compilers (if not all) have an explorer. An explorer is basicly the library to your game. It contains all your graphics, sounds, scripts, etc.
Sprite: 2D graphic. Do not confuse this with a texture. A sprite is more of an entity such as a player or a box.
Texture: 2D graphic that can also be implemented onto 3D objects. Textures in 2D games are referenced towards the basic building blocks of the game such as a texture of a wall or the ground. In 3D terms it is a 2D graphic that is wrapped around 3D models.
Model: A model is a 3D object that can be rendered in programs like Blender or Maya. I won't go much into this because it's quite complicated and you probably want to start off with 2D games.
There's a whole stuff load of other terms that would make your head explode so I'm just going to give you these ones for the time being. Do some research then get back to me when you're ready.
