What Is The Difference Between RAW And JPEG Photos?
RAW and JPEG are file formats. Photographers use both. JPEG images have an amount of processing and compressing done to them when a photo is taken. RAW photos have no processing done to them other than creating the file, that is.
JPEG photos can be viewed by anyone straight off the memory card. To view RAW photos, you need specialist software.
JPEG files are smaller than RAW files, but RAW files contain more data to work with than JPEG files.

Can You Edit RAW Photos In Lightroom?
You can edit RAW photos in Lightroom. RAW images open, and behave in exactly the same way as JPEG files, but with RAW files you get more options, choices and adjustments. RAW files are unprocessed on import into Lightroom. They need more work, but you can get better results. You need to export RAW photos out of Lightroom as JEPG files for other people to be able to open them.

RAW And JPEG - What Do They Mean? Which Is Better?
RAW and JPEG are picture-taking formats. When taking photographs using RAW no processing is applied to an image other than creating the image itself. When taking photos using the JPEG format the RAW data is processed in-camera at the time of image capture. JPEG files look better straight out of the camera, but RAW files record more tonal and colour data.
