Hi, I am a newbie in networking. I am going to start an internet service in a small and remote area but i still confused with the router and switch. I am planning to put about 21 computers in it. It will mostly be used for internet and not a lot of file sharing. How many switch and router do i need? Do I connect the ISP modem to router then switch or modem -> switch -> router? I would like to thank for any help in advance.
