Answer to Question 1

C

Answer to Question 2

Modern telephone and computer networks are converging into a single digital network using shared Internet-based standards and technology. Telecom companies offer full suites of telecommunication and Internet service. In the past, these two types of networks were distinct - telephone networks and computer networks performed completely different services and were not affiliated with one another. Additionally, modern communication networks are much faster and more cost effective than they were in the past.
