A Vector2 stores two floats, one for your X position and one for your Y position in cartesian coordinates. A Vector3 adds the Z position.
Say you wanted to move your character along the x axis. You can simply access the player's x value. You could do this with transform.Translate(5,0,0), where the character will move at a speed of five along the x, or you could access the x variable inside the transform.position Vector3 : transform.position.x += 5. Obviously you'd want to use time.DeltaTime and magic numbers are a no go but basically a Vector2 or a Vector3 are just two or three floats in one easy to manage variable :)Tue, 01 Apr 2014 19:58:06 GMTPOLYGAMeAnswer by senc01a

The concept of vector is broader than Unity in fact it comes from mathematics, usually studied in the early years of high school.
I recommend you to have a look at this video [What are Vectors][1], where you can find information about what they are and some of their operations (addition, product, etc).
Please also check this website, [Vectors for beginners][2], which I believe will clarify most of the questions you have at this stage.
2D and 3D vectors are essentially the same, only that 2D vectors only have 2 components (x,y), while 3D vectors have 3 (x,y,z).
In Unity you will be mostly working with 3D vectors as the space is three-dimensional. However, all of the operations apply to both type, and are similar.
