A router (also known as a “маршрутизатор” in Ukrainian) is a networking device used to direct data packets between computers in a network. The router acts as an intermediary between different networks, such as a home network and the Internet, and allows for data flow control and security.

Routers typically have at least two ports, which allow computers and other devices to connect to the network. They may also have wireless interfaces for connecting to wireless devices such as smartphones and tablets.

Routers can be used to configure network settings such as security, data transfer speed, and the placement of network nodes. They can also have features such as remote network access, content filtering, and network security through firewall settings.

Routers are an important component of any network, especially for connecting to the Internet, and allow for the connection of various devices to the network and the exchange of data.
