Sensors are devices that can take the light let into the camera and convert the bits of data into colored pixels, "digitalizing" it, if you will. The two sensors are CCD (charge coupled device) and CMOS (complimentary metal-oxide semiconductor) sensors. They each have their pros and cons and are used in different cameras for different reasons.
A device which captures the image and directs it to storage. It replaces the light-sensitive film in conventional cameras.

The difference is the lens, auto-focus, color and sharpness / detail of the picture, but this only depends on the two cameras that you are comparing.

Buying a digital camera can be disorienting. There are hundreds of cameras available at many different types of retail outlets (online and in traditional stores), with prices ranging from $75 to several thousand dollars. Some cameras are small enough to fit in a shirt pocket. Others are large and can weigh up to two pounds. .
Short answer: Yes. Long answer: Canon digital cameras are divided into two classes: Those with APS-C sensors (Rebel, 30D/40D/50D), and those with full-frame sensors (5d, 5d Mark II, 1D Mark II, 1D Mark III, 1Ds Mark III, ...). Those with full-frame sensors are the most similar to film cameras. Canon lenses are similarly divided into two classes: EF-S lenses, and EF / L lenses. L lenses (a subset of EF lenses) are indicated by a red band around the front of the lens, and are the highest quality Canon lenses. A 35mm Canon prime lens is an EF lens. It will work on any Canon digital camera. All Canon lenses work on all Canon cameras, with the exception that Canon EF-S lenses only work on Canon digital cameras with APS-C sensors (Rebel, 30D/40D/50D), because the lens is too small to cover the full frame of larger cameras (5d, 5d Mark II, 1D Mark II, 1D Mark II, 1Ds Mark III, etc.).
