1.1    INTRODUCTION.

          A computer is a piece of electronic equipment which accepts input of data using pre-defined instructions known as computer programs to execute the task in order to produce output (Anyaogu,2003).

According to Anyaogu, (2003), a computer program is a sequence of logically valid instructions which tells the computer what it is required to do. These programs or instructions are written in computer language. Software can be defined as that ordered sequence of instructions for changing the state of the computer hardware in a particular sequence which is usually written in high-level programming languages that are easier and more efficient for humans to use the machine language (www.wikiepedia.com).
