Definition of Information technology, its importance, three fictitious headlines to show the power of it.
Expert Solution & Answer
Explanation of Solution
Information technology involves the study and use of computers for storing, retrieving and transmitting information. It is often used in context with enterprise or business. IT can be considered as a part of Information and communication technology. Information technology plays an important role in many areas:
- Information technology plays an important role in business field by providing smooth functioning of their departments like manufacturing, security, finance and HR.
- Another importance of information technology is in the education field. It allows students to learn from online classes which are accessed through computers or laptops. Also, it allows students to submit their assignment anytime.
- Information technology plays an important role in healthcare field also. Nowadays, most of the hospitals and clinics send, receive medical information and reports digitally.
- Information technology plays an important role in security as well. Information technology provides security to online data from online transactions or any other alternative if data is accessed through a proper channel.
Three more fictitious headlines that can be added are:
- Is Facebook secure?
- Your privacy at risk: Facebook
- Social media: curse or blessing?

11. Go to the Webinars worksheet. DeShawn wants to determine the number of webinars the company can hold on Tuesdays and Thursdays to make the highest weekly profit without interfering with consultations, which are also scheduled for Tuesdays and Thursdays and use the same resources.
Use Solver to find this information as follows:
a. Use Total weekly profit as the objective cell in the Solver model, with the goal of determining the maximum value for that cell.
b. Use the number of Tuesday and Thursday sessions for the five programs as the changing variable cells.
c. Determine and enter the constraints based on the information provided in Table 3.
d. Use Simplex LP as the solving method to find a global optimal solution.
e. Save the Solver model below the Maximum weekly profit model label.
f. Solve the model, keeping the Solver solution.

- I want to ask someone who has experiences in writing physics based simulation software. For context I am building a game engine, and want to implement physics simulation. There are a few approaches that I managed to find, but would like to know what are other approaches to doing physics simulation entry points from scenes, would you be able to visually draw me a few approaches (like 3 approaces)? When I say entry point to the actual physics simulation. An example of this is when the user presses the play button in the editor, it starts and initiates the physics system. Applying all of the global physics settings parameters that gets applied to that scene. Here is the use-case, I am looking for. If you have two scenes, and select scene 1. You press the play button. The physics simulation starts. When that physics simulation starts, you are also having to update the physics through some physics dedicated delta time because physics needs to happen faster update frequency.
