Wireless Adapter: Wi-Fi Distributor or Receiver?

Question

Iron

Hello.
We spent the "new Internet", now the modem is far from the PC, and there is no particular desire to pull the wires. Decided to get a Wi-Fi receiver. I searched in Google, immediately gives out the online catalog with the "wireless adapters" section. Chose (and already ordered) this one .
Only now I am tormented by doubts because of one picture (3rd). There, as it were, it is drawn that 3 more laptops are connected to the laptop into which this device is inserted. And he is wired. Actually, isn't this "flash drive" a signal distributor? I need her to be able to receive a signal. And whether it will distribute - it does not matter absolutely. Should I call and cancel an order?
PS Sorry if this doesn't fit the theme of the community, I sincerely hope for your help.

It is both, that is, it can work both in receiver mode and in access point mode.
As, in fact, the vast majority of WiFi "whistles".
