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-explorer 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 Continue reading

Encryption is the most common and essentially the simplest way to protect any information. After all, it seems that it could be simpler to take the text, take some algorithm known to you and your friends and use the algorithm to make gibberish from the text that no one except you and your friends will parse. Simple and pretty angry. To date, the solution remains the most reasonable.

However, many may argue, “then what is the effectiveness and complexity of encryption?” But it is in the selection of the algorithm. At the moment, there are a huge number of encryption systems and ciphers. And each of them is unusually effective and complex to a certain extent. However, all of them are classified into two main categories: symmetric and asymmetric ciphers. Further we will focus on them. And already examining an example, we will show what data encryption is.
