MPEG-1 (Video CDs)
Although MPEG-1 supports higher resolutions, it is typically coded at 352x240 x 30fps (NTSC) or 352x288 x 25fps (PAL/SECAM). Full 704x480 and 704x576 frames (BT.601) were scaled down for encoding and scaled up for playback. MPEG-1 uses the YCbCr color space with 4:2:0 sampling, but did not provide a standard way of handling interlaced video. Data rates were limited to 1.8 Mbps, but often exceeded.
MPEG-2 (DVD, Digital TV)
MPEG-2 provides broadcast quality video with resolutions up to 1920x1080. It supports a variety of audio/video formats, including legacy TV, HDTV and five channel surround sound. MPEG-2 uses the YCbCr color space with 4:2:0, 4:2:2 and 4:4:4 sampling and supports interlaced video. Data rates are from 1.5 to 60 Mbps.

Well this is a 2 part answer. From the developer point of view, it is just the next generation of video compression (smaller files, with better video and audio). It started with MPEG1, then improvements were made which were released in MPEG 2, MPEG3 and 4 (so on and so on). From the end user point of view, if your system plays MPEG2 it will play MPEG 1. Most of the time, anything with a *.mpg file name will cause a media player to open depending on the OS.
