Switch = Divided throughput?

Hello,

I'm trying to expand my network.
I know this is a question that has been asked several times, but the answers from different sources are contradictory.

I have a Freebox in NON-router mode (which I need to keep for the VOIP line) to which I have connected a WiFi router (an Airport Extreme base station). Three machines are connected to it. I need to extend my network for two more machines. I was planning to add a simple switch (like a DLink GS1008) to one of the Ethernet ports, and that would be it?
But several people (including the salesman at FNAC) have told me that, unlike a router, the bandwidth will automatically be divided among the different machines connected to it. For example, if I connect two PCs, even if only one machine is downloading, I will only have half of the available bandwidth, etc.

I read the article below, which I believe seems to say the opposite. Even if it is not very clear. I also know that manufacturers often create confusion with terms.

Anyway, what is your opinion?

The bandwidth will not be divided through a switch.
If you connect a hub, the bandwidth will be divided since it broadcasts to all ports.
The switch only acts as an intermediary.

Will it be divided if only 1 of the devices uses bandwidth? For example, I connect my PC and my TV to the hub, and I only use the PC, but the TV is on standby. Will I still have divided bandwidth?

Hello,

you're talking about a switch, not a hub; anyway, hubs haven't existed for a long time.

But in the case you describe, whether hub or switch, nothing is divided; if only one device works, it's like connecting a direct cable between the input and output, except that with a direct cable, the PC won't be able to communicate with the TV, but with the switch or hub, it can.
