What do these mean (attached), please?

[High1]

There is a wireless PC and a Ethernet-connected PC (DON-PC) connected to the same router (192.168.0.1) and nothing else, and I wondered what all these 'active connections' were?

Is it anything to concern myself about?

Thank you.

You are the only person on the network.
You are 192.168.0.2 in the list you attached.
The number after the IP is a port number. You have programs or some service that requires special ports for services.
The use and purpose of the ports is explained here:
