<u>Networks were originally used as a government weapon 61 years ago</u> to <u>communicate information</u> such as data and research. However, individual networks were eventually discontinued by the government and made open to the public to use for things such as PAN, LAN, MAN, WAN, SAN, and so on.
<u>Our internet today is capable of communicating with bilions of computers.</u> This is possible due to your modem using radio wave-like speeds to connect to your ISP. Your ISP then connects to a larger network, which is connecting to thousands of other networks. You see, <u>the internet is just a large network of networks that are connected through very fast radiowaves</u>. However, it is not just a single network being used anymore; it's thousands of them. The term, "internet" was used to describe this large selection of networks. In short, <u>B</u><u> would be incorrect. </u>
