It's kind of a deceptive pic, as typical routers include a 4-port switch, meaning you could connect those three machines directly to the router, providing the same functionality, without purchasing the standalone switch. As a matter of fact, the router they pictured has a 4-port switch.
The router pictured would allow you to connect 4 machines to share the internet. Adding a switch to the mix, which would connect to one of the router's 4 ports would allow for even more machines; three machines and a switch connected to the router plus however many machines that switch will allow. All with internet access.
