Plural form of words ending in -us

In the English language, the plural form of words ending in -us, especially those derived from Latin, replaces -us with -i. Many exceptions exist, some because the word does not derive from Latin, and others due to habit (for example, campus, plural campuses). Conversely, some non-Latin words ending in -us and Latin words that did not have their Latin plurals with -i form their English plurals with -i. Between these extremes are words that do not justify a Latin plural on etymological grounds, but that native English speakers commonly pluralize with -i (for example, octopi as a plural for octopus). Whether to regard these alternative plural forms as incorrect depends on one's position in the ongoing debate over prescriptivism versus descriptivism in linguistics and language education.

History

Virus (LaFee song)

"Virus" is a song written by Bob Arnz and Gerd Zimmermann and recorded by German singer LaFee. It was released as the first single from LaFee's debut album LaFee. The single reached fourteen in both the German and Austrian Singles Charts when released in March 2006. An English version of the song, entitled "Scabies", later appeared on LaFee's third studio album Shut Up.

Virus (1999 film)

Virus is a 1999 science fiction action thriller film directed by visual effects artist John Bruno. Starring Jamie Lee Curtis, William Baldwin and Donald Sutherland, the film is based on a Dark Horse comic book of the same name by Chuck Pfarrer.

Plot

The Russian space station Mir contacts a research ship in the South Pacific, Akademik Vladislav Volkov. While the crews of both ships converse, a large energy source traveling through space strikes the Mir. The electrical surge hijacks the Mir and beams itself down to the oceangoing ship, disabling it. The crew of Mir are killed, while the large research vessel's crew suffer an unknown fate.

Seven days later, during a typhoon, the tugboat Sea Star, captained by alcoholic Robert Everton (Donald Sutherland), loses its uninsured cargo, which was the captain's last chance to get out of debt. Sea Star's crew, led by navigator and ex-Navy officer Kelly Foster (Jamie Lee Curtis) and engineer Steve Baker (William Baldwin) discover the engine room taking on water; Foster suggests that they take refuge in the eye of the storm to make repairs. Everton agrees, but while Sea Star rests in calm waters, he contemplates committing suicide. At the same time, the Akademik Vladislav Volkov appears on Sea Star's radar, and realizing that it could be worth millions in salvage, Everton orders his crew aboard.

COM file

A COM file is a type of simple executable file. On the Digital Equipment operating systems of the 1970s, .COM was used as a filename extension for text files containing commands to be issued to the operating system (similar to a batch file). With the introduction of CP/M (a microcomputer operating system), the type of files commonly associated with COM extension changed to that of executable files. This convention was later carried over to MS-DOS. Even when complemented by the more general .exe file format for executables, the compact COM files remain viable and frequently used in MS-DOS.

The .COM file name extension has no relation to the .com (for "commercial") top-level Internet domain name. However, this similarity in name has been exploited by malicious computer virus writers.

MS-DOS binary format

The COM format is the original binary executable format used in CP/M and MS-DOS. It is very simple; it has no header (with the exception of CP/M 3 files), and contains no standard metadata, only code and data. This simplicity exacts a price: the binary has a maximum size of 65,280 (FF00h) bytes (256 bytes short of 64 KB) and stores all its code and data in one segment.

JPEG

JPEG (/ˈdʒeɪpɛɡ/ JAY-peg) is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPEG typically achieves 10:1 compression with little perceptible loss in image quality.

JPEG compression is used in a number of image file formats. JPEG/Exif is the most common image format used by digital cameras and other photographic image capture devices; along with JPEG/JFIF, it is the most common format for storing and transmitting photographic images on the World Wide Web. These format variations are often not distinguished, and are simply called JPEG.

The term "JPEG" is an abbreviation for the Joint Photographic Experts Group, which created the standard. The MIME media type for JPEG is image/jpeg, except in older Internet Explorer versions, which provides a MIME type of image/pjpeg when uploading JPEG images. JPEG files usually have a filename extension of .jpg or .jpeg.

DOS

DOS /dɒs/, short for disk operating system, is an acronym for several computer operating systems that were operated by using the command line.

MS-DOS dominated the IBM PC compatible market between 1981 and 1995, or until about 2000 including the partially MS-DOS-based Microsoft Windows (95, 98, and Millennium Edition). "DOS" is used to describe the family of several very similar command-line systems, including MS-DOS, PC DOS, DR-DOS, FreeDOS, ROM-DOS, and PTS-DOS.

In spite of the common usage, none of these systems were simply named "DOS" (a name given only to an unrelated IBM mainframe operating system in the 1960s). A number of unrelated, non-x86 microcomputer disk operating systems had "DOS" in their names, and are often referred to simply as "DOS" when discussing machines that use them (e.g. AmigaDOS, AMSDOS, ANDOS, Apple DOS, Atari DOS, Commodore DOS, CSI-DOS, ProDOS, and TRSDOS). While providing many of the same operating system functions for their respective computer systems, programs running under any one of these operating systems would not run under others.
