Local Area Networks and the Internet

When a local area network is connected to the global Internet, one of the PCs, called a server, becomes a kind of conductor and connects to the Internet using a modem or in some other way, while other computers operate through it, they are also called workstations. Just like any of us has a mailing address where we receive mail letters, each computer is assigned an IP address for functioning in the Internet environment, but usually it has only a computer conductor directly connected to the Internet.

If the computer is connected through a modem, it usually receives a dynamic address from the service provider. It is assigned automatically and is valid for a specific time. While there is also a static address, a permanent address for an unlimited period of use. At least two network devices are usually connected to the gateway computer (server): a modem and a network card, so it actually has two IP addresses, real and internal, which the network card receives on the local network.

All the information about you is … on the Internet

The fact that computers have long and reliably entered the lives of almost every person no longer surprises anyone. This “iron” makes us capable of many things: it allows us to expand our horizons, improve our skills, and receive various kinds of information without much effort.

But the more we use a computer, the more acute the problem of computer security becomes. Indeed, a computer that is not connected to the network itself can hardly be at risk of data hacking or virus infection. Is it that an inept user will forget to check for a “contagion” flash drive or other removable storage medium. That is, the main threat to computer security outside the network is viruses of all types and stripes.

Your “footprints” on the net
But with the first Internet connection, there are many more threats than ordinary viruses. You think that registration on all kinds of sites is a waste of time and does not threaten anything, that your surfing on various web resources cannot be tracked, and no one knows which pages you regularly visit. However, each registration on the forum, in chat or in the “contact”, the entrance to the online store or viewing blogs leaves its “mark” in the network space. Continue reading
