When a neutron star is "born" [See related question], it emits a steady beam of electromagnetic radiation. When this beam is directed towards Earth it is called a Pulsar. [See related question]
See related link for a pictorial of the beam.
If the beam is not directed towards Earth, then it is only observed as a neutron star because we cannot detect the electromagnetic radiation beam.
As a neutron star slowly ages (10 -> 100 million years), this beam slowly "switches" off and the pulsar is no more.
So all neutron stars in their early stage, emit a steady beam of electromagnetic radiation, but it's only called a pulsar if it's directed towards Earth.

∙ 8y ago1. A neutron star is cooling down and does not emit any electromagnetic radiation, whereas a pulsar will always be hot and emit a huge amount of electromagnetic radiation.
WHY?
If the supernova is really strong, it may tear out some electrons from the core, so that the core will be only made of ions. The ions' electrons and protons will then be squashed onto neutrons with an electrical charge. After the supernova has occurred, the core alone will be left. It will be very small and spin really fast. As far as we all know, if electricity (object with an electrical charge) is spinning (making circles), it emits beams of electromagnetic radiation. The more electricity there is, the faster it goes the more electromagnetic radiation it emits. Because a pulsar is unbelievably dens (has a mass of about 10 Suns and has a diameter from half a mile to 20 km. A peanut there would way millions of tons) and spins about 30 times a second around its axis, it emits a huge amount of electromagnetic radiation. It is strong enough to attract some massive objects. It is bright and hot (produces energy), because it turns the objects it attracts (which are coming in the form of dust and gas) into solid. This produces loads of energy.
If the supernova is not that powerful, it does not tear out enough electrons from the core, so the core will be made of atoms. As far as we know, atoms do not have electrical charge. If that's the case, a neutron star will be formed.
2. There is no such a car called the 'Neutron star', whereas the 'pulsar' is a variety of Nissan.

∙ 10y agoA black hole is a region of spacetime containing mass of such density that nothing, including light, can escape. Black holes are thought to most commonly be formed by gravitational collapse at the end of the life of more massive stars.
A quasar is a highly energetic object in the center of a massive galaxy, an active galactic nucleus powered by a supermassive black hole, its powerful radiation caused by infalling matter around its accretion disk. Quasars are considered the brightest (and most distant) objects in the universe.
A pulsar is a type of neutron star, highly magnetized and radiating in apparent pulses due to its rotation. A pulsar is not, nor does it contain, a black hole; and does not have an event horizon (i.e., escape velocity is less than the speed of light). Neutron degeneracy pressure in a pulsar is deemed sufficient to prevent its further collapse into a black hole (barring other events such as added mass from infalling matter).

∙ 8y agoA neutron star is the collapsed core of a massive star that destroyed itself in a supernova. It is so dense that even that atoms that made up the core have been crushed, leaving behind an interior made of neutrons.

∙ 9y agoNo. A pulsar is a neutron star, but not all neutron stars are pulsars. A pulsar is a rapidly spinning neutron star that funnels large amounts of radiation through its magnetic field.

What do you mean when you say every pulsar is a neutron star but not every neutron star is a pulsar?
All "pulsars" are neutron stars - it's just "we" term pulsars as neutron stars who's orientation towards us shows the beam of electromagnetic radiation. Other neutron stars who's orientation, do not point towards us are not called pulsars, although they exhibit the same characteristics.
Are pulsars found in supernova remnants.?
Yes. All pulsars and neutron stars are the remnants of a supernova explosion.
Are all neutron stars also pulsars?
Evidence suggests that all Neutron stars are pulsars or were once pulsars. In theoretical physics; the existence of objects like quark stars, preon stars, or electroweak stars is called into question. These are usually used to explain radio quiet neutron stars; however, far more likely these objects simply do not pulse at any rate in our relative direction.
Some neutron stars that emit pulses of radiation called?
Gamma rays
The connection between pulsars and neutron stars is explained by what model?
The is no connection - they are one and the same. See related question.
Are pulsars a kind of neutron star?
Pulsars are not only a kind of neutron star, they are neutron stars. See related question.
Where do pulsars originate from?
The collapse of massive stars - the same as neutron stars.
Why are you studying pulsars?
Because I am interested in neutron stars.
Flickering neutron stars formed in supernovas?
pulsars

Are pulsars found in supernova remnants.?
Yes. All pulsars and neutron stars are the remnants of a supernova explosion.
Where are pulsars located in space?
Pulsars are located every where around the universe keep in mind pulsars are neutron stars so that means they were formed by large stars that have aged and died out
Are all pulsars neutron stars?
All young neutron stars in reality are "pulsars". However, for a neutron star to be termed a pulsar, it's magnetic axis has to point towards Earth. (So we can see the pulse, even though all young neutron stars have a pulse, they cannot be observed from Earth.)
How are pulsars formed?
Pulsars are rapidly rotating neutron stars that emit beams of electromagnetic energy. Neutron stars form when the core of a massive star collapses and goes supernova leaving behind a neutron star which will begin rotating and releasing energy.
Why are pulsars hot?
Pulsars and neutron stars are hot because of all the residual heat left over in the core of the original star.
Are all neutron stars also pulsars?
Evidence suggests that all Neutron stars are pulsars or were once pulsars. In theoretical physics; the existence of objects like quark stars, preon stars, or electroweak stars is called into question.
