As far as ISO performance and light gathering ability, think of it like this:
Say you have a Nikon D90 and a Nikon D700 as examples, both are 12 Megapixel sensors. meaning the D90's (crop sensor) 12 million pixels are crammed into a smaller sensor and the larger sensor of the D700 (full frame) has more area to spread those 12 megapixels out so light can hit each pixel "easier" for lack of a better term and gather more light because of the larger size of each pixel, whereas the D90's smaller pixels that are crammed together make it harder for the light to reach all of the pixels leading to more noise in your photograph. Same goes for pocket cameras. The sensor is so small anything past ISO 400 usually yields unpleasant photos
