Bit (money)

The word bit is a colloquial expression referring to specific coins in various coinages throughout the world.

United States

In the United States, the bit is equal to one eighth of a dollar or 12 ¹⁄₂ cents. In the U.S., the "bit" as a designation for money dates from the colonial period, when the most common unit of currency used was the Spanish dollar, also known as "piece of eight", which was worth 8 Spanish silver reales. One eighth of a dollar or one silver real was one "bit".

With the adoption of the decimal U.S. currency in 1794, there was no longer a U.S. coin worth ¹⁄₈ of a dollar but "two bits" remained in the language with the meaning of one quarter dollar, "four bits" half dollar, etc. Because there was no one-bit coin, a dime (10¢) was sometimes called a short bit and 15¢ a long bit. (The picayune, which was originally ¹⁄₂ real or ¹⁄₂ bit (6 ¹⁄₄¢), was similarly transferred to the US 5¢-piece.)

In addition, Spanish coinage, like other foreign coins, continued to be widely used and allowed as legal tender by Chapter XXII of the Act of April 10, 1806 until the Coinage Act of 1857 discontinued the practice.

List of Tron characters

This article covers notable characters of Tron franchise, including all of its various cinematic, literary, video game adaptations and sequels.

Development

For the first film, Richard Rickitt explains that to "produce the characters who inhabit the computer world, actors were dressed in costumes that were covered in black-and-white computer circuitry designs....With coloured light shining through the white areas of their costumes, the resulting characters appeared to glow as if lit from within....optical processes were used to create all of the film's computerized characters..." Frederick S. Clarke reports that "Tron: Legacy will combine live action with CGI," adding that "several characters...will be completely digital..."

Tron

Kevin Flynn

Kevin Flynn is a former employee at the fictional software company ENCOM and the protagonist of the first film. He is played by Jeff Bridges.

At the start of the first film, he is manager of "Flynn's", a video arcade where he impresses his patrons with his skills at games that (unknown to them) he designed at ENCOM, but remains determined to find evidence that CEO Ed Dillinger plagiarised Flynn's work to advance his position within the company. Throughout most of the film, Flynn travels around the digital world, accompanying the eponymous character Tron; but later discovers that as a User, he commands the physical laws of the digital world, enabling him beyond the abilities of an ordinary program. Eventually, he enables Tron to destroy the Master Control Program shown to oppress the digital world, and upon return to the material world obtains the evidence necessary to expose Dillinger, and becomes ENCOM's CEO himself.

Array data structure

In computer science, an array data structure, or simply an array, is a data structure consisting of a collection of elements (values or variables), each identified by at least one array index or key. An array is stored so that the position of each element can be computed from its index tuple by a mathematical formula. The simplest type of data structure is a linear array, also called one-dimensional array.

For example, an array of 10 32-bit integer variables, with indices 0 through 9, may be stored as 10 words at memory addresses 2000, 2004, 2008, ... 2036, so that the element with index i has the address 2000 + 4 × i.

Because the mathematical concept of a matrix can be represented as a two-dimensional grid, two-dimensional arrays are also sometimes called matrices. In some cases the term "vector" is used in computing to refer to an array, although tuples rather than vectors are more correctly the mathematical equivalent. Arrays are often used to implement tables, especially lookup tables; the word table is sometimes used as a synonym of array.

Matrix (mathematics)

In mathematics, a matrix (plural matrices) is a rectangular array of numbers, symbols, or expressions, arranged in rows and columns. The dimensions of matrix (1) are 2 × 3 (read "two by three"), because there are two rows and three columns.

The individual items in a matrix are called its elements or entries. Provided that they are the same size (have the same number of rows and the same number of columns), two matrices can be added or subtracted element by element. The rule for matrix multiplication, however, is that two matrices can be multiplied only when the number of columns in the first equals the number of rows in the second. Any matrix can be multiplied element-wise by a scalar from its associated field. A major application of matrices is to represent linear transformations, that is, generalizations of linear functions such as f(x) = 4x. For example, the rotation of vectors in three dimensional space is a linear transformation which can be represented by a rotation matrix R: if v is a column vector (a matrix with only one column) describing the position of a point in space, the product Rv is a column vector describing the position of that point after a rotation. The product of two transformation matrices is a matrix that represents the composition of two linear transformations. Another application of matrices is in the solution of systems of linear equations. If the matrix is square, it is possible to deduce some of its properties by computing its determinant. For example, a square matrix has an inverse if and only if its determinant is not zero. Insight into the geometry of a linear transformation is obtainable (along with other information) from the matrix's eigenvalues and eigenvectors.
