Malicious code: A serious damage such as destruction of data or creating a nuisance by sending unwanted messages is called as a malicious code. There are many categories of malicious codes: Virus: The self-replicating program which is malicious and embeds itself into another program is called as computer “virus”. Trojan horse: A kind of program that is helpful in some way but creates a different kind of problem when it gets executed. Worm: A standalone program that targets network resources is called as a worm. It sends copies of itself to the network by consuming the bandwidth. Logic bomb: The malicious code that executes when a certain system-oriented event occurs is called as a logic bomb.

(using R)The iris data set in R gives the measurements in centimeters of the variables sepal length and width andpetal length and width, respectively, for 50 flowers from each of 3 species of iris, setosa, versicolor, andvirginica. Use the iris data set and the t.test function, test if the mean of pepal length of iris flowers isgreater than the mean of sepal length.The iris data set in R gives the measurements in centimeters of the variables sepal length and width andpetal length and width, respectively, for 50 flowers from each of 3 species of iris, setosa, versicolor, andvirginica.
