Color images have the potential to convey more information than a monochrome or black and white images. Each pixel for a true color image is stored as values of red, green, and blue. However, the RGB color model is not an efficient representation for compression task because there is significant correlation between RGB color components. Therefore, for compression, luminance-chrominance representations (such as YIQ) is implemented.

The expansion of computer networks and the use of Internet in every side of our life, and the importance of Computer and Network security, , computer aided learning Security System is utilized to make many security attacks and services easier to be applied and understood by students and other people.The proposed system will mainly be divided into two parts, Application mode and Documentation mode. In the two modes, the system will be in two parts: Attack and Defense. In the Attack and Defense, the well known security tools will be covered.

The work presented here describes a web-based digital library system for Iraqi universities. This system is capable of executing the search function of digital libraries. Library information is present in centralized database which is collected from different library systems of Iraqi universities and it provides their access through website.The system utilizes MySQL database to store the collected data from library systems in Iraqi universities. Web technology is used for accessing library data by using HTML & PHP. Apache server is also used.
