Local Area Networks and the Internet

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.

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.
