ALGORITHAM
Algorithm is a series of steps to reach the solution state or goal. These steps when implemented in the computer, invariably leads to solution of the problem.
In computer systems, an algorithm is basically an instance of logic written in software by software developers to be effective for the intended "target" computer(s), in order for the target machines to produce output from given input (perhaps null). [The null character (also null terminator), abbreviated NUL, is a control character with the value zero.]
ORIGINATION
An algorithm (pronounced AL-go-rith-um) is a procedure or formula for solving a problem. The word derives from the name of the mathematician, Mohammed ibn-Musa al-Khwarizmi, who was part of the royal court in Baghdad and who lived from about 780 to 850. Al-Khwarizmi's work is the likely source for the word Algebra as well.
A computer programme can be viewed as an elaborate algorithm. In mathematics and computer science, an algorithm usually means a small procedure that solves a recurrent problem.
