In a lay man’s language the CGI is a specific method that facilitates the exchange of information or data between two ends; in one end there is the web server and on the other end there is the browser or the client of web. Actually the CGI is a series of standard through which a program can send data to the server to be processed. For this one has to use standard HTML tags to acquire data from an individual and after getting this data it is sent to any CGI routine. Here the CGI routine processes the data.

The common gateway interface or CGI facilitates easy transmission of data for the web user on her request. It creates a platform where such transaction of data becomes quite easy. Under this CGI program the data transmits on the request of web user to program application and finally passed to the web user. In other words, the CGI is a basic way of transmission of data or information from the server of web on the request of the user for the application of program.
