They are both image formats and they both support different color modes.
Raster: commonly used for photographic images
Also called "bitmap", raster is an image format where information is stored in a grid of pixels(see image below) and the color of each pixel is individually defined. The more frequent the pixels/dots are the sharper and more detailed the image will appear. These images are not easily scalable because they have a fixed resolution.Common file types that support raster images: JPG, TIFF, BMP, GIF
Vector: commonly used for line/shape artAn image format that contains individual and scalable objects(see image below) that are defined by mathematical formulas. They can be displayed at any size and are easily scaled because they are resolution independent.Common file types that support vector images: EPS, PDF

Rule of Thumb: Raster images are much more common than vector images.
