For the lighthouse on Oahu, see Barbers Point Light (Hawaii).

Barber's Point Light was a lighthouse on Lake Champlain in New York.

It was established and lit in 1873 and was deactivated in 1935. The foundation materials were blue limestone and the lighthouse was constructed out of Blue Limestone and wood. The shape of the tower was octagnal. The tower was white and the lighthousekeeper dwelling had a black trim. The original lens installed in 1873 was a fifth order Fresnel lens.

-[[Image:Wikipedia in binary.gif|thumb|The word 'Wikipedia' represented in [[ASCII]] binary.]]
+'''Barber's Point Light''' was a [[lighthouse]] on [[Lake Champlain]] in [[New York]].
-'''Binary code''' is the system of representing [[text]] or [[Instruction (computer science)|computer processor instructions]] by the use of a two [[numerical digit|digit]] [[number system]]. This system is composed of only the number zero, representing the [[Off (state)|off]] state, and the number one, representing [[on]] state, combined in groups of 8. These groups of 8 [[bit|bits]] can represent up to 256 different values and can correspond to a variety of different symbols, letters or instructions. An example of this is the uppercase A, which in [[ASCII]] binary is 01000001.
+It was established and lit in 1873 and was deactivated in 1935.  The foundation materials were blue limestone and the lighthouse was constructed out of Blue Limestone and wood.  The shape of the tower was octagnal.  The tower was white and the lighthousekeeper dwelling had a black trim.  The original lens installed in 1873 was a fifth order [[Fresnel lens]].
-In computing and telecommunication, it is used for any of a variety of methods of coding data, such as sequences of [[character]]s, into sequences of groups of [[bit]]s, including fixed-width [[word (computing)|words]] or [[byte]]s,  and [[variable-length code]]s such as [[Huffman code]] and [[arithmetic coding]].
+==External links==
-In a fixed-width binary code, each letter, digit, or other character, is represented by a sequence of bits of the same length, usually indicated in code tables by the [[octal]], [[decimal]] or [[hexadecimal]] notation for the value of that sequence of bits interpreted as a [[binary number]].

+{{Lighthouses of New York}}
-For representing texts in the [[Latin alphabet]] often a fixed width 8-bit code is used. The [[ISO 8859-1]] character code uses 8 bits for each character e.g. "R" is "01010010" and "b" is "01100010"; the block of 8 [[bit]]s is called a [[byte]]; it extended the earlier [[ASCII]] code, based on the version of the Latin alphabet used for [[English (language)|English]], which uses 7 bits to represent 128 characters (0–127).
+{{coord missing|United States}}
-The [[Unicode]] standard defines several [[variable-width encoding]]s and the fixed-width 32-bit (4-byte) [[UTF-32]] code, potentially having room for [[1,000,000,000 (number)|billion]]s of characters, but using barely more than 1 million combination as definable code points.
+[[Category:Lighthouses in New York]]
-A binary sequence can be translated into a decimal number using the following formula, with <math>y</math> being the 1/0:
+{{NewYork-struct-stub}}
-<math>(2^0 \times y) + (2^1 \times y) + (2^2 \times y)\ \dots</math>
+{{US-lighthouse-stub}}
-Repeat the bracket and increase the exponent for every 1/0 in the sequence. It is important to remember that the formula is used on the sequence from right to left.
