    A router is used to connect two different networks, in TCP/IP, two different subnets, such as and Systems on those two networks that want to communicate need to have a router between them.

    A standard switch (not a layer 3 "routing switch") separates the collision domains of Ethernet, but lets all the systems connected to it share the same network, e.g. would all plug into 1 or more switches, depending on the number of systems.

    Prior to Gigabit, there were Ethernet "hubs" that connected systems on a network, the difference being that a hub is a single collision domain (see Wiki on Ethernet).

    Any computer plugged into a hub can see all the traffic to all the computers on a network. A computer plugged into a switch can only see the traffic it is sending and receiving.
