A prime Lens has a fixed focal length and does not zoom in any way - It is often used for Landscape and portrait photography.
A zoom lens can change its focal length within the lens' designated range. They are often used by press as they would require to take photo both at wide angle and telephoto in quick succession.
Field of View is determined by the angle of view from the lens out to the scene.
Focal Length is the distance between the end of the lens and the subject it's focussing on.
In 35mm photography, a standard lens would have a focal length of 50mm. It would be referred to as a "normal" lens as it neither magnifies or reduces the image. It would have a field of view of 46˚.
Wide angle lenses have a short focal length to capture more. They capture more because they have a wide picture angle, unlike telephoto lenses, which have a narrower picture angle.
