The orbits were first introduced in Bohr's theory. According to it, orbits were circular paths for electrons, around the nucleus. It is two dimensional.
On the contrary, the orbitals deals with the Shrodinger's Wave Equation. They show a probable three dimensional space where a particular electron can exist around the nucleus. Further, the shapes of the orbitals are determined from the solutions of the equation.
Bohr's atomic model depicts the electron shells and orbitals as being two dimensional, staying the exact same distance away from the nucleus the entire time. Today, we know that electron orbits are three dimensional, and at best can only say where the electron in a given orbital is most likely to be at any given time, except for the f orbitals, as no one really knows for sure what those look like yet.
Bohr's model explains how electron transitions cause hydrogen's atomic emission spectra. The quantum model is a 3-d view of the atom, which shows an electron's energy levels and sublevels and the probability of an electron's location, proven with complex mathematics.
Neil Bohrs atomic model is simply called Bohrs model. It states that electrons have a certain amount of energy, so they must follow certain orbits. This is different from the modern atomic model.

yes, they are depicted by a red subatomic particle.

The Bohr model!
Assuming circular orbits, Bohr proposed that the angular momentum L of an electron in its orbit is quantized, that is, it has only specific, discrete values. The value for L is given by the formula L=mevrn=nh2π(n=1,2,3,…)
Niels Bohr devised the Bohr model, which depicts the atom as a small, positively charged nucleus surrounded by electrons that travel in circular orbits around the nucleus, with electrostatic forces providing attraction.http://en.wikipedia.org/wiki/Bohr_model
the planetary model
yes, they are depicted by a red subatomic particle.
atoms
The Bohr atom imagined that electrons orbit the nucleus in much the same way that planets orbit the sun. The modern atomic model has electrons in the form of a cloud that surrounds the nucleus without actually moving in orbit around it. Moving electrons would have to emit photons, lose energy, and spiral into the nucleus, thus destroying the atom. They don't really orbit.
