Crawler-based search engines are what most of us are familiar with - mainly because that's what Google and Bing are. These companies develop their own software that enables them to build and maintain searchable databases of web pages (the engine), and to organise those pages into the most valuable and pertinent way to the user.

The definition of network is:

kondaur [170]

$\text{Hello there!}$

Networks were originally used as a government weapon 61 years ago to communicate information 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.

Our internet today is capable of communicating with bilions of computers. 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, the internet is just a large network of networks that are connected through very fast radiowaves. 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, B would be incorrect.

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, A would not be correct.

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

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