Nowadays it is possible to connect computers to a single network and organize the exchange of information between them, So what is a network? What types are there? What are the concepts of the Internet, intranet, electronic communication, what constitutes their technical, software, information software, their creation and operation, understanding of their importance and the ability to work directly for every member of today's society important.

Computer networks come in different forms: home network, business network, and the Internet are three examples. Devices can use a variety of methods to connect to these (and other types) networks. There are three main types of network connections:
Point-to-point connections allow one device to connect directly to another device. For example, two phones can be interconnected to share contact information or photos.
The broadcast / multicast connection allows the device to send a single message to the network, and copies of this message are delivered to multiple recipients.
Multi-directional connections allow you to connect and deliver messages directly to multiple devices in parallel.
Not all network technologies support all types of connections. Ethernet signature connections, such as support broadcasts, but no IPv6. The following sections describe the different types of connections that are widely used in networks today.
