What does a managed switch do that a cheap non managed switch cannot?

A non managed switch only does one thing: it switches, which means it enables devices in the network to communicate. Managing switches allows you to change settings. You can disable unused ports, restrict network access, limit speed, prioritize traffic, adjust parameters, and more.

What are the benefits of having a management switch for home networks?

For most families, this really doesn't have much benefit. In fact, for many devices that operate independently of each other, connecting to the internet through WiFi is more than enough. However, if you have a smart home and want to integrate multiple devices together for single point control, you may find managing switches very useful. By using a managed switch, you will be able to:

Close a single port

Restrict network access

Isolate devices on the network and control who can access what devices

View data statistics for each port

Record switch information over time through a computer

Implement advanced security

Last sentence

It should be emphasized that most households do not need to manage switches. However, if you have a smart home with multiple IoT devices and want to integrate and control them, a managed network switch may be your right choice.
