Is this a telephoto camera lens?

I need help finding out if this is a telephoto lens or not. It is an AF-S Nikkor 55-300mm 1:4.5-5.6 G ED
and it also says DX SWM VR ED HRI 1.4m/4.59 ft
It looks like this &imgrefurl=http://www.photoxels.com/tag/af-s-dx-55-300mm-vr-ii/&usg=__yhzfG0MxbVEVAtdZe8gk-Hf7Y9k=&h=452&w=800&sz=74&hl=en&start=0&zoom=1&tbnid=lIf5QobWrR5HDM:&tbnh=119&tbnw=211&ei=6Ul0TabdNsOBlAeOl9WZBQ&prev=/images%3Fq%3DAF-S%2BNikkor%2B55-300mm%2B1:4.5-5.6%2BG%2BED%26um%3D1%26hl%3Den%26sa%3DN%26biw%3D1440%26bih%3D809%26tbs%3Disch:1&um=1&itbs=1&iact=hc&vpx=124&vpy=101&dur=4365&hovh=169&hovw=299&tx=171&ty=84&oei=6Ul0TabdNsOBlAeOl9WZBQ&page=1&ndsp=24&ved=1t:429, r:0, s:0

How do you know if it is a telephoto lens or not?

55mm is about normal but yes, 300mm is definitely telephoto. Actually, about 70mm and up is considered telephoto.

Yes, that is a telephoto zoom.

The term 'telephoto' refers to how the lens is built. A telephoto lens is physically shorter than its focal length because it incorporates a special lens group (called a telephoto group). The telephoto group extends the light path in the lens to give it a longer focal length in a shorter overall length than a normal long-focal length lens.

Many manufacturers include detailed information about their lenses on their websites; you should be able to tell from the product description if a lens is telephoto or not.
