In this modern era of world everything is resides in a computer which require high level of security to protect that data. Now a day's many Authentication techniques are available to provide authentication to the data on a Network. Security can provide by using different type of passwords. Password can be textual password or Graphical Passwords which are having their drawbacks like many attacks can be possible on this type of password in order to break it i.e. eves dropping, dictionary attacks, social engineering, shoulder surfing, brute force attack. In this paper we are going to propose a system where we are using Text and Colors as password in order to Provide Security to the Application on internet.

The study investigated the effect of multimedia Instructional approach on secondary school students’ achievement in mathematics in Owerri Municipal Council of Imo State. Quasi-experimental research design was used for the study adopting the pre-test, post-test non-equivalent control type. The population of the study consist of 3,266 senior secondary school two (SS11) students in Owerri Municipal Council. A sample of 165 students from two randomly selected secondary schools was used for the study. In each of the two schools selected, two intact classes were randomly selected and assigned experiment or control groups respectively. Experiment group was taught mathematics using multimedia instructional approach while the control group was taught using conventional “chalk and talk” approach. The instrument used for data collection was a 30 item researcher made objective questions titled “Mathematics Achievement Test”(MAT). It had reliability coefficient of 0.85 determined through Person’s Product Moment Correlation coefficient method. The data generated was analysed using mean and standard deviation to answer research questions while ANCOVA was used to test hypotheses at 0.05 level of significance. The result showed that, Multimedia Instructional Approach enhanced students’ achievement in mathematics across gender and ability levels. Based on the findings, it was recommended that mathematics teachers should be trained on the use of multimedia instructional approach in teaching and learning at the secondary school levels.
