Unix filesystem

In Unix and operating systems inspired by it, the file system is considered a central component of the operating system. It was also one of the first parts of the system to be designed and implemented by Ken Thompson in the first experimental version of Unix, dated 1969.

Like in other operating systems, the filesystem provides information storage and retrieval, as well as interprocess communication, in the sense that the many small programs that traditionally comprise a Unix system can store information in files so that other programs can read these, although pipes complemented it in this role starting with the Third Edition. Additionally, the filesystem provides access to other resources through so-called device files that are entry points to terminals, printers, and mice.

The rest of this article uses "Unix" as a generic name to refer to both the original Unix operating system as well as its many workalikes.

Principles

The filesystem appears as a single rooted tree of directories. Instead of addressing separate volumes such as disk partitions, removable media, and network shares as separate trees (as done in MS-DOS and Windows: each "drive" has a drive letter that denotes the root of its file system tree), such volumes can be "mounted" on a directory, causing the volume's file system tree to appear as that directory in the larger tree. The root of the entire tree is denoted /.

Bin (city)

Bin (Chinese: t 豳, s 彬, p Bīn) was a Chinese settlement during the Xia and Shang dynasties. It was said to be located between the Rong and Di barbarians. It was possibly located near Qingcheng in Gansu and is the modern namesake of Bin in Shaanxi.

Bin was the ancestral home of the Ji clan after Buzhu moved them from Tai after resigning his post in the Xia. The clan maintained control over the settlement until Ancient Duke Danfu removed them again and led his people to Zhou along the Wei River.

Human back

The human back is the large posterior area of the human body, rising from the top of the buttocks to the back of the neck and the shoulders. It is the surface opposite to the chest, its height being defined by the vertebral column (commonly referred to as the spine or backbone) and its breadth being supported by the ribcage and shoulders. The spinal canal runs through the spine and provides nerves to the rest of the body.

Structure

The central feature of the human back is the vertebral column, specifically the length from the top of the thoracic vertebrae to the bottom of the lumbar vertebrae, which houses the spinal cord in its spinal canal, and which generally has some curvature that gives shape to the back. The ribcage extends from the spine at the top of the back (with the top of the ribcage corresponding to the T1 vertebra), more than halfway down the length of the back, leaving an area with less protection between the bottom of the ribcage and the hips. The width of the back at the top is defined by the scapula, the broad, flat bones of the shoulders.

Back (novel)

Back is a novel written by British writer Henry Green and published in 1946.

Plot summary

The novel tells the story of Charley Summers, a young Englishman who comes back from Germany, where he was detained as a POW for three years after having been wounded in combat in France (possibly in 1939-1940). Summers is repatriated because, due to his wound, his leg had to be amputated. While he was prisoner, Rose, the woman he loved, died, and this adds to the shock Charley suffered because of the mutilation. Moroever, Rose was married to another man, so Charley cannot even express his bereavement for fear of scandal.

After having visited the grave of Rose and met her husband James there, Charley calls on Rose's father, Mr Grant, who encourages him to make acquantance with a young widow. Charley ignores the suggestion at first, but after some days he goes to the widow's flat and he is astonished at the uncanny resemblance between the woman, whose name is Nancy Whitmore, and Rose. He soon finds out that there is a very simple explanation for this: Nancy is the illegitimate daughter of Mr Grant, who sent Charley to her thinking he might console her of the death of her husband (an RAF pilot killed in action in Egypt).
