C (programming language)

2009-03-19T01:26:57Z

JaviarC:

'''C''' is the name of a [[procedural programming|procedural]], [[imperative programming|imperative]] [[programming language]] developed in 1972 by Dennis Ritchie at Bell Laboratories. It was a major improvement over the earlier languages BCPL and B.

C is still a popular choice for projects where speed and small program size are important considerations, such as embedded firmware. A significant portion of the [[Linux]] [[kernel]] was written in C. The syntax of C inspired many later languages such as [[C++]], [[Java]] and [[C Sharp]]. Many C compilers also support low-level programming via integrated inline assemblers.

This programming language is now used and marketed more heavily by Microsoft.

JaviarC: small, but important.

'''Computer science''' is the study of various aspects of [[computers]]. It is a common source of study and degrees at the college level and beyond.

Studies can range from the very practical, such as learning programming languages, to the highly theoretical.

Students who plan to study computer science should take as many [[mathematics]] courses as possible. While not all of computer science is directly mathematical, the mental discipline that comes from studying math is very useful in studying computers.

Gold

JaviarC: Karats are not really a measurement persay

'''Gold''' is a chemical [[element]]. It is a precious [[metal]] which has been used as [[money]]. Gold is found in nature as nuggets or grains in rocks, underground and in deposits. It is a soft, shiny, yellow metal, and is normally measured in [[Carat|Karats]]. A Karat refers to how much of a substance is gold, with 14 Karat being the most common. Gold is usually mixed with other elements because of how soft and pliable it is.

Gold is the basis for a monetary standard used by the International Monetary Fund (IMF) and the Bank for International Settlements (BIS).

Because gold is highly conductive and very resistant to [[oxidation]], it is vital in electronics. Gold plating is used on switch contacts, printed circuit boards, and device leads. There is enough gold in electronic devices to make it worthwhile to process discarded devices in order to reclaim the gold in them.

Gold was one of the three [[Gifts of the Magi]], along with [[frankincense]] and [[myrrh]].<ref>Matthew 2:11 [http://www.blueletterbible.org/kjv/Mat/Mat002.html#11]</ref>

Gold is also used in [[jewelry]]. However, the [[New Testament]] instructs [[Christian]] [[women]] not to wear gold or [[pearl]]s.<ref>I Timothy 2:9 [http://www.blueletterbible.org/kjv/1Ti/1Ti002.html#9]</ref> Other uses of gold include aerospace, awards, bullion, coinage, computers, currency backing, dentistry, electronics, glassmaking, gold gilding and gold leaf and medical. <ref>[http://geology.com/minerals/gold/uses-of-gold.shtml The Many Uses of Gold], Geology.com, accessed December 11, 2008</ref>

Copper

JaviarC: Small add-on.

Copper, the 29th element, is a [[metal]]. In industry it is praised for its extreme [[ductility]] and [[electrical conductivity]] which make it an excellent material for [[wires]]. Copper is also a nutrient [[mineral]], and is required by the human body to perform certain chemical reactions.

Copper is also important culturally, as one of the first metals to be used by humankind, especially in its alloy form [[bronze]]. Even today the pennies in the United States are informally referred to as "coppers."

The atomic symbol for copper, Cu, comes from the [[Latin]] ''cuprum'' which also gives its name (via [[Greek]]) to [[Cyprus]], an island nation in the Mediterranean renowned for its wealth of copper.

Copper is usually mixed with tin to form [[bronze]], and was a key metal during the [[Bronze Age]].
