A worldwide system composed of interconnected networks for information exchange is called:

• A. Internet
• B. Intranet
• C. Extranet
• D. LAN

Answer: (A)

The idea being tested is a global framework of networks that connect systems together to move information anywhere in the world. The Internet is exactly that—a worldwide system of networks that communicate using standardized protocols (like TCP/IP) to exchange data, emails, web pages, and files across countries and organizations. It isn’t confined to a single building or company, which distinguishes it from the other terms: a LAN covers a local area such as a single office or campus; an intranet is a private network used within an organization; and an extranet extends restricted access to selected external partners. The World Wide Web sits on top of the Internet as a vast collection of accessible documents, but the broader concept described here is the Internet itself.
