The internet is the name given to the entire public network which provides the infrastructure for the transfer of data between remote points. Such data can take the form of email, web pages, files, multi-media and just about anything else that exists in digital form.
Whilst the internet seems like one giant network is in reality a mesh of interconnected networks held together by routers which control and direct the flow of data from point to point until it reaches its destination.
The internet is completely open and as such there is no way to control what takes place on it. Whilst much of the activity on the internet is harmless it is also a fertile breeding ground for those with malicious intentions. It is for this reason that any computers or networks with access to the internet must be protected by a firewall.
