Boolean Searching on the Internet A Primer in Boolean Logic The Internet is a vast computer database. As such‚ its contents must be searched according to the rules of computer database searching. Much database searching is based on the principles of Boolean logic. Boolean logic refers to the logical relationship among search terms‚ and is named for the British-born Irish mathematician George Boole. On Internet search engines‚ the options for constructing logical relationships among search

Boolean Functions - Computer Organization (IT 25) BOOLEAN FUNCTIONS A Boolean function consists of a binary variable denoting the function‚ an equals sign and an algebraic expressions formed by using binary variables the constants 0 and 1‚ the logic operation symbols‚ and parentheses. For a given value of the binary variables‚ Boolean function can be equal to either 1 or 0. Example: F = X + Y’Z The two parts of the expression X and Y’Z‚ are called terms of the function F. The function

Arithmetic and Logical Operations Chapter Nine There is a lot more to assembly language than knowing the operations of a handful of machine instructions. You’ve got to know how to use them and what they can do. Many instructions are useful for operations that have little to do with their mathematical or obvious functions. This chapter discusses how to convert expressions from a high level language into assembly language. It also discusses advanced arithmetic and logical operations including multiprecision
