What is a router and how it works
In simpler terms, this is a device that, without additional orders, decides to send various packages (these can be, such as files - movies, games, documents, and the Internet) between the computers connected to it.
The device is different, but the standard switch is a compact device with built-in antenna, the hardware itself, the cord and the power.
The main thing is not to confuse them with the switch - they are two different things. Let's see the difference between the router and the switch. With the help of a switch, you can only create my locale between multiple computers.
Because all devices connected to the switch must have the same IP address on the subnet. The router can connect multiple networks together, with different IP addresses.
Why you need a router
The idea of combining local networks into a single global signifies the creation of methods, as one of them will seek the other. Therefore, it is possible to compare device data with the sender at the entrance: it determines who, where and what exit, and also examines the entry.
