Yes, they are devices that operate at different layers of the OSI model for networking.
when you are connecting same devices like computer to computer or switch to switch or router to router to use cross over cable. when you are connecting different devices like computer to switch or computer to router to use straight cable.
Network+ Guide to Networks answer: Bridge, Switch, Router
The number of devices you can link to a router will depend on the specific router,typically 4 devices can be connected.

Yes, switch as well as hub and router are network devices.
there can be many devices connected between a router and a switch the most popular items are firewall , ips , ids there are other devices such as network management tools
crossover cables must be used between 2 devices from the same level like (pc & pc - Pc & router - router & router) but strait through cable used between 2 different levels like (pc & switch - router & switch )
switch and hub
Use a switch
To connect two devices of the same type together. e.g. You would use a crossover cable to connect a router to another router, a switch to another switch or a computer to another computer. If you are connecting diferent devices together, such as a router to a switch, a straight through cable should be used.
"RJ-45 Cross cable" is required for a direct ethernet connetion between two pcsbetween the same type of network devices (PC-to-PC, switch-to-switch, router-to-PC (Note: router and PC are LIKE devices, because both are DTE)) you use Crossover cable.to connect different type of devices (PC-to-switch, PC-to-router ..) you use Straight Through cable.
