Structure
In the past, the structure may have consisted of eleven or thirteen pointers, but most modern file systems use fifteen pointers. These pointers consist of (assuming 15 pointers in the inode):
- Twelve pointers that directly point to blocks of the file's data (direct pointers)
- One singly indirect pointer (a pointer that points to a block of pointers that then point to blocks of the file's data)
- One doubly indirect pointer (a pointer that points to a block of pointers that point to other blocks of pointers that then point to blocks of the file's data)
- One triply indirect pointer (a pointer that points to a block of pointers that point to other blocks of pointers that point to other blocks of pointers that then point to blocks of the file's data)

Famous quotes containing the word structure:
“Slumism is the pent-up anger of people living on the outside of affluence. Slumism is decay of structure and deterioration of the human spirit. Slumism is a virus which spreads through the body politic. As other “isms,” it breeds disorder and demagoguery and hate.”
—Hubert H. Humphrey (1911–1978)
“If rightly made, a boat would be a sort of amphibious animal, a creature of two elements, related by one half its structure to some swift and shapely fish, and by the other to some strong-winged and graceful bird.”
—Henry David Thoreau (1817–1862)
“Man is more disposed to domination than freedom; and a structure of dominion not only gladdens the eye of the master who rears and protects it, but even its servants are uplifted by the thought that they are members of a whole, which rises high above the life and strength of single generations.”
—Karl Wilhelm Von Humboldt (1767–1835)
