Switches, like the ones by Ubiquiti, are necessary devices for connecting several computers and creating a network. Through this connection it is possible to transfer data between the different computers.
This is especially necessary for the creation of larger networks. This is because a switch is able to connect different devices while keeping communication separate from each other.
Among the numerous applications are LAN parties and office networks.
In addition, there are switches in different architectures, modes of operation and characteristics.
This leads to the question of which switch fits your application area.
