Answer 1

JPEG (Joint Picture Expert Graphics) and RAW are the filetypes used by digital cameras or any computers. All the compact digital cameras uses the JPEG format. It is a compressed format that's why you can store so many photographs in a small memory card. But there are quality settings as well for JPEG. In a digital camera, whatever information the camera captures from the sensor, it does some enhancements like sharpness and colour corrections and then saves it in a JPEG format. JPEG is a lossy compression (this means you loose some image information).

RAW format is mostly used by professional cameras. RAW is a lossless compression. The file size is massive so you can only store a few pictures. Also the camera doesn't do any enhancement. The information stored in RAW files is exactly the same as captured from the sensor. It allows you to do post production on your computer using a software like Adobe Photoshop.
