Switches are of two types: unmanaged and managed. Based on your needs, you can go for the right one. If you have an unmanaged switch, you can just take it out of the box and put it to use without making any changes. Typically, home-networking equipment uses unmanaged switches.
If you have a managed switch, you will need to make changes to it. In other words, you can monitor and adjust the switch based on your need. With this switch, you can control network traffic as well as decide who can access the network.
