an Information Systems are hardware, software, and telecommunications networks. The hardware refers to machinery, which includes central processing unit, keyboard, monitor, and mouse. TB–2. Describe various methods for entering data into and interacting with a computer. Keyboards are used to breakdown linguistic input and software commands into individual units of meaning. Track pads or a mouse can be used to point, draw, simulate the behavior of other devices such as a paintbrush or…

Computer technology progressed rapidly since the 1900’s. Computers are no longer scarcely around, many people have them and use them on a daily basis. They have also become an important source of evidence in criminal activities. Computers are very helpful for homicide investigators, because they can discover whether methods on how to murder were researched on the internet, if anything suspicious can be found in emails, or if threats were made towards the victim prior to the murder.

Random forest is used in this paper but usually to predict via using univariate method. But this time they used a multivariate method that being Random Forest. Random forest is good for microarray data and shows when the predictive data is “noisy, it can be used when the number of variables is much larger than the number of observations.” Their results in this paper showed that random forest has comparable performance compared to others including SVM and KNN. It also…

Having the necessary information is crucial in almost any area, especially for research and development. The purpose of collecting data is primarily for knowledge discovery, then for further consideration. In other words, all websites gather people’s information and base on them to explore their behaviours and trends. From there, they will shape the browsing experience that match each person’s preference in the future. As mentioned above, social media, especially Facebook and Google, track all…
