MPEG-4 - Stands for Moving Picture Experts Group. MPEG-4 generally produces better-quality video that other formats. MPEG-4 is a compression/decompression technology that aims to achieve interactivity, efficiency and stability in narrow-band transmissions.

MPEG - Is a digital video and audio compression format that was designed by the ISO (International Standards Organization) MPEG is a ‘lossy’ compression method which uses Interframe compression. Interframe Compression three types of frames which are: I-Frames, P-Frames and B-Frames.

DVD - Also known as Digital Versatile Disc, or Digital Video Disc. It is an optional disc-storage media format, and was developed and invented by Sony, and Phillips in 1995. Its main uses are video and data storage. DVD’s are the same dimensions as compact discs but store more than six times as much data as them.

CD-ROM - Compact disc read-only memory. Is a pre-pressed compact disc that contains data accessible to, but not writable by, a computer for data storage and music playback. CD-ROMs are popularly used to distribute various software, including games and multimedia applications. Some CDs hold both computer data and audio and being able to play on a CD Player where as some CDs can only be used on a computer only - These are called enhanced CDs.
