Audio Video InterleaveAudio Video Interleave (also Audio Video Interleaved and known by its initials and filename extensionAVI, usually pronounced ) is a proprietary multimedia container format and Windows standard introduced by Microsoft in November 1992 as part of its Video for Windows software. AVI files can contain both audio and video data in an uncompressed file container that allows synchronous audio-with-video playback.

MP4 file formatMP4 (formally MPEG-4 Part 14) is a digitalmultimediacontainer format most commonly used to store video and audio, but it can also be used to store other data such as subtitles and still images. Like most modern container formats, it allows streaming over the Internet. The only filename extension for MPEG-4 Part 14 files as defined by the specification is .mp4.Interchange File FormatInterchange File Format (IFF) is a generic digital container file format originally introduced by Electronic Arts (in cooperation with Commodore) in 1985 to facilitate transfer of data between software produced by different companies. IFF files do not have any standard filename extension. On many systems that generate IFF files, file extensions are not important because the operating system stores file format metadata separately from the file name.
File formatStructure of information stored on a computer wav-file: 2.1 megabytes. ogg-file: 154 kilobytes. A file format is the way that information is encoded for storage in a computer file. It may describe the encoding at various levels of abstraction including low-level bit and byte layout as well high-level organization such as markup and tabular structure. A file format may be standardized (which can be proprietary or open) or it can be an ad hoc convention.
Microsoft WindowsWindows is a proprietaryoperating system developed by Microsoft. Windows is grouped into families that cater to particular sectors of the computing industry – Windows for personal computers, Windows Server for servers, and Windows IoT for embedded systems. Windows itself is further grouped into that cater to different users – Home for home users, Professional for advanced users, Education for schools, and Enterprise for corporations.
ZIP (file format)ZIP is an archive file format that supports lossless data compression. A ZIP file may contain one or more files or directories that may have been compressed. The ZIP file format permits a number of compression algorithms, though DEFLATE is the most common. This format was originally created in 1989 and was first implemented in PKWARE, Inc.'s PKZIP utility, as a replacement for the previous ARC compression format by Thom Henderson.MetadataData about other dataIn the 21st century, metadata typically refers to digital forms, but traditional card catalogs contain metadata, with cards holding information about books in a library (author, title, subject, etc.).Metadata (or metainformation) is data (or information) that defines and describes the characteristics of other data. It often helps to describe, explain, locate, or otherwise make data easier to retrieve, use, or manage.
Computer fileA computer file is a named collection of data treated as a unit by the system that manages it. Today, this system is called a file system. Many older computer systems lacked a distinct file system per se, yet a management feature is required in order to provide a file abstraction. Files can be shared with and transferred between computers and mobile devices via removable media, networks, or the Internet. Different types of computer files are designed for different purposes.
Archive fileAn archive file stores the content of one or more computer files, possibly compressed and/or encrypted, with associated metadata such as file name, directory structure, error detection and correction information, and commentary. An archive file is often used to facilitate portability, distribution and backup, and to reduce storage use. An archive file is usually generated and modified via a file archiverutility.X.690X.690 is an ITU-T standard specifying several ASN.1 encoding formats: Basic Encoding Rules (BER)Canonical Encoding Rules (CER)Distinguished Encoding Rules (DER)The Basic Encoding Rules (BER) were the original rules laid out by the ASN.1 standard for encoding data into a binary format. The rules, collectively referred to as a transfer syntax in ASN.1 parlance, specify the exact octets (8-bit bytes) used to encode data.
