What is diffrent between router and switch?
we use straight cable to connect between the router and switch as router and switch are different devices.
A router that supports two or more communications protocols, such as IP and IPX. It is used to switch network traffic between different LANs located throughout the enterprise as well as to switch LAN traffic to WANs.
Two different network connections would require a router, not a switch.
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 )
If a switch is connected to a router then the MAC address of the router is known to the switch through that port. A host takes advantage of this by using the default gateway address (the address of the router) which the switch "knows" by its lookup table. Therefore, the switch can learn the address automatically and no configuration is necessary.
A switch/router
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.
A switch cannot function as a router. But you can plug a switch in to one of the ports on the router if you need additional ports.
"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.
