Simulate a traffic light with three small square text boxes placed vertically on a form. See
Fig. 2.29. Initially, the bottom text box is solid green and the other text boxes are dark gray.
When the Tab key is pressed, the middle text box turns yellow and the bottom text box turns
dark gray. The next time Tab is pressed, the top text box turns red and the middle text box
turns dark gray. Subsequent pressing of the Tab key cycles through the three colors. Hint: First place the bottom text box on the form, then the middle text box, and finally the top text box.

- What are the steps you will follow in order to check the database and fix any problems with it? Have in mind that you SHOULD normalize it as well. Consider that the database offline is not allowed since people are connected to it and personal data might be bridged and not secured.

- I need help to resolve the following activityarrow_forwardModern life has been impacted immensely by computers. Computers have penetrated every aspect of oursociety, either for better or for worse. From supermarket scanners calculating our shopping transactionswhile keeping store inventory; robots that handle highly specialized tasks or even simple human tasks,computers do much more than just computing. But where did all this technology come from and whereis it heading? Does the future look promising or should we worry about computers taking over theworld? Or are they just a necessary evil? Provide three references with your answer.arrow_forwardWhat are the steps you will follow in order to check the database and fix any problems with it? Have in mind that you SHOULD normalize it as well. Describe in full, consider the following:• Taking the database offline is not allowed since people are connected to it.• Personal data might be bridged and not secured.
