algorithm

Contributor(s): Fouad Tawfiq and Ali

An algorithm (pronounced AL-go-rith-um) is a procedure or formula for solving a problem, based on conducting a sequence of specified actions. A computer program can be viewed as an elaborate algorithm. In mathematics and computer science, an algorithm usually means a small procedure that solves a recurrent problem.

Algorithms are widely used throughout all areas of IT (information technology). A search engine algorithm, for example, takes search strings of keywords and operators as input, searches its associated database for relevant web pages, and returns results.

An encryption algorithm transforms data according to specified actions to protect it. A secret key algorithm such as the U.S. Department of Defense's Data Encryption Standard (DES), for example, uses the same key to encrypt and decrypt data. As long as the algorithm is sufficiently sophisticated, no one lacking the key can decrypt the data.

The word algorithm 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.

Algorithms: It is a step by step procedure of solving a problem.
E.g. 1
Consider a problem of multiplying two numbers
Solution
Step 1: Input the numbers as a and b
Step 2: Find the product of a x b
Step 3: Print the result

E.g. 2
To add two numbers
Solution
Step 1: Input the numbers as x, y
Step 2: Sum=x+y
Step 3: Print Sum

Note: The pictorial representation of algorithm is called Flow Chart.
