Library Index [View category: Information Technology Discuss Article Feature: Understanding Boolean Search Article is yet to be rated Author: Submitted: 01-Jan-1970 01:00:00 Imported From: zZine (original author: h3raLd) These days, it is necessary to use a search engines to find the information you want. Learning how to search Imagine yourself in the shoes of someone who has never used the Internet before. That's pretty rare nowadays, but it does happen. Take my dad, for example, who recently asked me something like "Where can I find a map of the Internet?". I explained that there wasn't any such thing because the Web is too dynamic to be mappable, and that's why we use search engines. ruby on rails free hosting I immediately find various blog entries referring to a project that aims to offer free hosting to try out the Ruby-based framework "Rails Playground". [3] It seems to be the perfect solution - they offer, completely free, enough space to try out Rails. It's a pity they recently decided to close new account registration, so now the whole thing is useless. Variants of the search query mentioned above bring up stuff related to Rails Playground. The project became so well-known that almost every Rails-related blog mentioned it at some point as the only place offering free hosting supporting Rails. Since it is useless now, is there a way to prevent Google (or other search engines) from displaying Rails Playground related results? Yes!

Boolean algebra From Conservapedia Jump to: navigation search Boolean algebra is a division of mathematics which deals with boolean variables, which are variables which can only have two values. Typically these values are and 1, especially within the fields of electronics or computers , however boolean variables can have other values, such as "true" and "false". Boolean algebra was invented in the nineteenth century by an English mathematician named George Boole. Contents Three Basic Operations AND OR NOT ... edit Three Basic Operations The three basic operations of boolean algebra are AND ( multiplication ), OR ( addition ), and NOT. See the table below for a numerical description. From these functions, the other functions of boolean algebra can be derived. AND: A•B=C OR: A+B=C NOT A'=B A B C A B C A B edit AND AND is the boolean equivalent of multiplication. The product of two numbers are non-zero if both numbers are non-zero. In words, the AND function states: "If A AND B are true then C is true". The AND function is commutative, so it results in the same answer no matter what order the values are in. For example, A • B = B • A, and A • (B • C) = (A • B) • C. Just as in traditional algebra exponents can be represented as a series of multiplications in boolean algebra, but the results are different. A

British mathematician George Boole developed a form of algebra that uses symbolic logic to define relationships in sets - unions and intersections to be precise. In electrical engineering, we do not usually bother ourselves with all the rigors and formalities of the pure mathematical application. Rather, since engineers actually build things that perform useful functions, most of us can get by with the basic operations presented below. Venn Diagrams do not help much when designing a digital circuit where complex (or simple for that matter) conditional decisions must be made to determine the proper output of a multiplexer or an entire production line controller circuit. Instead, we use Truth Tables, State Machines and Karnaugh Maps There are three fundamental operators from which all other Boolean functions can be derived - the OR gate, the AND gate, and the NOT (negation) operator. The Exclusive OR gate is included even though it is not a fundamental function, but it is very commonly used. Venn Diagrams for each of the functions are give just for illustration. White regions are where the functions are True, and blue areas are False. OR x y x + y The OR Symbol AND x y x y The AND Symbols Exclusive OR x y x Å y NOT x x The NOT Symbol x + = x x 1 = x x + x x x x + x = x x x = x x + 1 = 1 x Theorems Involution Commutative x + y = y + x x y = y x Associative x + (y + z) = (x + y) + z Distributive x (y + z) = x y + x z x + y z = (x + y) (x + z) DeMorgan (x + y) x y (x y) x y Absorption x + x y = x x (x + y) = x
