What does "Vector" mean in nodes as input and output? Please explain

Question

What does Vector mean in nodes input and output in Blender?

it is made to send and receive 3D informations (what happens on X, Y and Z) — moonboots, Nov 09 '21 at 13:37
if you don't know what a vector is....maybe you should learn first some basic math....and a node is just a function, which you give a/some values and it returns a/some values. That's all. So basically...i do not understand your question!? — Chris, Nov 09 '21 at 13:40

It's just x, y, and z-coordinates (which may actually represent x, y, and z-coordinates or angles in radians). In some nodes, it represents a single point of an object (like origin), in others it may represent all points of an object (I think this moment is cumbersome). — ENIAC, Sep 11 '22 at 16:49

Well as the name implies, it's a vector, a 3 dimensional vector with 3 components x, y and z. It's different from, for example, the scalar (grey) socket which is a scalar value or the yellow socket which is a color value (consisting actually of 4 components R, G, B, and A or 3 if we have no Alpha).

You can see the vector socket as 3 grey sockets combined and the color socket as 4 grey sockets combined (3 without Alpha).

You can use the Converter>Combine XYZ, Converter>Combine RGB, Converter>Combine RGBA to convert from scalar value to vector, RGB or RGBA respectively.
