An annual report is a comprehensive report on a company’s activities throughout the preceding year.

Annual reports are intended to give shareholders and other interested people information about the company’s activities and financial performance.

They may be considered as grey literature. Most jurisdictions require companies to prepare and disclose annual reports, and many require the annual report to be filed at the company’s registry.

Companies listed on a stock exchange are also required to report at more frequent intervals (depending upon the rules of the stock exchange involved).

Audio Raport

The MP3 lossy audio data compression algorithm takes advantage of a perceptual limitation of human hearing called auditory masking. In 1894, the American physicist Alfred M. Mayer reported that a tone could be rendered inaudible by another tone of lower frequency. In 1959, Richard Ehmer described a complete set of auditory curves regarding this phenomenon.

Ernst Terhardt et al. created an algorithm describing auditory masking with high accuracy.This work added to a variety of reports from authors dating back to Fletcher, and to the work that initially determined critical ratios and critical bandwidths.

Because the DOC file format was a closed specification for many years, inconsistent handling of the format persists and may cause some loss of formatting information when handling the same file with multiple word processing programs.

Some specifications for Microsoft Office 97 binary file formats were published in 1997 under a restrictive license, but these specifications were removed from online download in 1999.

Specifications of later versions of Microsoft Office binary file formats were not publicly available. The DOC format specification was available from Microsoft on requestsince 2006 under restrictive RAND-Z terms until February 2008.

Audio Video Interleave

Audio Video Interleaved (also Audio Video Interleave), known by its initials AVI, is a multimedia container format introduced by Microsoft in November 1992 as part of its Video for Windows software.

AVI files can contain both audio and video data in a file container that allows synchronous audio-with-video playback. Like the DVD video format, AVI files support multiple streaming audio and video, although these features are seldom used.

Most AVI files also use the file format extensions developed by the Matrox OpenDML group in February 1996. These files are supported by Microsoft, and are unofficially called “AVI 2.0”.

Anual Report (archive)

The .ZIP file format was created by Phil Katz of PKWARE. He created the format after his company had lawsuits filed against him by Systems Enhancement Associates (SEA) claiming that his archiving products were derivatives of SEA’s ARC archiving system.

The name “zip” (meaning “move at high speed”) was suggested by Katz’s friend, Robert Mahoney. They wanted to imply that their product would be faster than ARC and other compression formats of the time. The earliest known version of .ZIP File Format Specification was first published as part of PKZIP 0.9 package under the file APPNOTE.TXT in 1989.

The .ZIP file format was released into the public domain
