Overview
This file format stores both audio and video files for playback purposes. It is used to store files that are of high quality as file compression is less in this extension. Windows OS uses this as the default format to store multimedia files but other operating systems such as Linux, Unix and Mac also support this. The data in it is encoded by various codecs such as DivX and XviD. There is a variety of software that support these files. For instance- Microsoft Movies & TV, Windows Media Player and Apple QuickTime player; etc. Due to its low compression ability, it is widely used to make short movies, promos and advertisements; etc. It should be noted that AVI format result in large files that is why it is rarely used for video streaming.
Technical description
In AVI extension, file's data is divided into blocks or chunks as it is a sub-format of RIFF(Resource Interchange file format). An identification of each chunk is done by FourCC tag. File header and metadata of video(like height, width and frame rate) are identified by ‘hdrl tag' which is sub-chunk and it is mandatory. There is one another chunk which is also obligatory that is ‘movi tag' and it has actual audio or video data. The last sub-chunk is ‘idx1 tag' and it records the offsets of the data chunks. This ‘idx1 tag' is completely optional. There is one limitation of this format that it does not contain variable bitrate data.

Overview
WAV or WAVE is an audio format which was developed to store audio files on personal computers. These files include music, spoken or speech audios and sound effects. The size of the files in this codec is very large as it does not use a lossy format like MP3. This is the main reason why this format has lost its popularity. Due to its size, it is hard to transfer files over the internet which had resulted in less acceptance. This format is supported by many programs like a window Media player. Therefore, these audio files can be played using aforesaid software. One can not completely ignore this format as it provides high quality of audios. Due to this, it is used for radio broadcasting.
Technical description
This format supports metadata that is why we can add details using information chunk. Data in this codec is stored in chunks as it is an application of RIFF(Resource interchange file format). Furthermore, LPCM(Linear pulse code modulation) is the most common, uncompressed audio format in this, but it can also store compressed audio like MP3. Also, it is especially used by professionals as LPCM audio format offers a maximum quality. Only files up to 4 GB are supported by this format which is one of the limitations in this format. This is because of 32-bit unsigned integer which carries the file size header. To overcome this, W64 format came into existence which can record long audios as it enables 64-bit header.
