\text{Hello there!}

<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>

The worldwide web is a protocol used by the internet to connect to select websites favourably from whoever's using it. This obviously would not define the network, as this is something that's used by it. Furthermore, <u>A</u><u> would not be correct.</u>

As described already, the network was a selection of computers used to communicate information to each other. <u>C </u><u>would not be correct </u>as it states that there is only one computer being used.

\fbox{Therefore, D would be the correct answer.}

Karo-lina-s [1.5K]

Answer:

<u>VLANs</u>

Explanation:

Virtual LANs (VLANs) are a type of network connection or arrangement of network devices in the same broadcast domain. They are called Virtual LANs because they represent fractions or subgroups in the switch ports found in an Ethernet LAN.

Indeed, because of their topological arrangement, this reduces the security risk of unauthorized access to sensitive data or devices since the host can be placed on a different VLAN. Hence, in this scenario, using this network feature would allow visitors to plug into these ports to gain internet access, but they would not have access to any other devices on the private network.

Answer:

if(i>1)

{

Console.WriteLine(i*i);

Console.WriteLine(i*i*i);

Explanation:
