This site has a brief summary on the differences between the two:

In simple terms, modem encodes and decodes the signals coming thru optical/telephone/other cables and router routes/redirects the signal across different systems.

Modem- give you internet on lan/wifi/usb as o/p from telephone adsl line input.

Router-Splits the input across output.For eg the output of modem can
be given to router.The router can now share that as output on multiple lan
ports and wifi.

To put it simple
Modem - Only one machine can access Internet
Router - Many machines can access Internet from single Net Connection

Correction, if modem is more then one RJ45 port, many machines can access internet.

In short a milti port ( 3x or 4x RJ45+ 1 USB) modem can act as a Router
