Primer

Primer may refer to:

Primer (textbook)

A primer (in this sense usually pronounced /ˈprɪmər/, sometimes /ˈpraɪmər/) is a first textbook for teaching of reading, such as an alphabet book or basal reader. The word also is used more broadly to refer to any book that presents the most basic elements of any subject.

The Latin Enschedé Abecedarium of the late 15th century, translated into English as the Salisbury Prymer, has been identified as the earliest example of a printed primer. It presented the alphabet and several Catholic prayers.

Other historical examples of primers for children include The New England Primer (1680s) and McGuffey Readers (1836) in the US, and Bala Potam (Lessons for Children, 1850 & 1851) by Arumuka Navalar in Sri Lanka.

Primer (film)

Primer is a 2004 American indie science fiction drama film about the accidental discovery of a means of time travel. The film was written, directed, produced, edited and scored by Shane Carruth, who also stars in the main role.

Primer is of note for its extremely low budget (completed for $7,000), experimental plot structure, philosophical implications, and complex technical dialogue, which Carruth, a college graduate with a degree in mathematics and a former engineer, chose not to simplify for the sake of the audience. The film collected the Grand Jury Prize at the 2004 Sundance Film Festival, before securing a limited release in the United States, and has since gained a cult following.

Plot

Two engineers -- Aaron and Abe -- supplement their day-jobs with entrepreneurial tech projects, working out of Aaron's garage. During one such research effort, involving electromagnetic reduction of objects' weight, the two men accidentally discover an 'A-to-B' time loop side-effect; objects left in the weight-reducing field exhibit temporal anomalies, proceeding normally (from time 'A,' when the field was activated, to time 'B,' when the field is powered off), then backwards (from 'B' back to 'A'), in continuous A-then-B-then-A-then-B sequence, such that objects can leave the field in the present, or at some previous point.

Input

Input may refer to:

Factors of production

In economics, factors of production, resources, or inputs are what is used in the production process to produce output—that is, finished goods and services. The amounts of the various inputs used determine the quantity of output according to a relationship called the production function. There are three basic resources or factors of production: land, labour, and capital. These factors are also frequently labeled "producer goods" to distinguish them from the goods or services purchased by consumers, which are frequently labeled "consumer goods." All three of these are required in combination at a time to produce a commodity.

Factors of production may also refer specifically to the primary factors, which are land, labor (the ability to work), and capital goods applied to production. Materials and energy are considered secondary factors in classical economics because they are obtained from land, labour and capital. The primary factors facilitate production but neither become part of the product (as with raw materials) nor become significantly transformed by the production process (as with fuel used to power machinery). Land includes not only the site of production but natural resources above or below the soil. Recent usage has distinguished human capital (the stock of knowledge in the labor force) from labor. Entrepreneurship is also sometimes considered a factor of production. Sometimes the overall state of technology is described as a factor of production. The number and definition of factors varies, depending on theoretical purpose, empirical emphasis, or school of economics.

Input (computer science)

In computer science, the general meaning of input is to provide or give something to the computer, in other words the state/act of a computer, component of a computer or relevant device being accepting something from the user, from a device or from a piece of software either automatically or manually is called input.

We categorize computer devices as input devices because we use these devices to send instructions to the computer, we are sending our "Input" to the computer, some common examples of computer input devices are:

We may also call some inner parts of the computer as input components to the other components, like the power-on button of a computer is an input component for the processor or the power supply, because it takes user input and sends it to other components for further processing.

In many computer languages the keyword "input" is used as a special keyword or function, such as in Visual Basic or Python, the word "input" is used to get text input from the user.
