A digital computer is a useful tool for solving a great variety of problems. A solution to a problem is called an algorithm; it describes the sequence of steps to be performed for the problem to be solved. A simple example of a problem and an algorithm for it would be:
Problem: Sort a list of names in ascending lexicographic order. Algorithm: Call the given list list1; create an empty list, list2, to hold the sorted list. Repeatedly find the ‘smallest’ name in list1, remove it from list1, and make it the next entry of list2, until list1 is empty.
An algorithm is expressed in abstract terms. To be intelligible to a computer, it needs to be expressed in a language understood by it. The only language really understood by a computer is its own machine language. Programs expressed in the machine language are said to be executable. A program written in any other language needs to be first translated to the machine language before it can be executed.
