Re: Difference between a switch and a router
The switch alone is responsible for moving the connections at intervals not know. To tell chart, the switch does what it does with the receptionist a commuter: contests, find out who they want to speak and communicates the call to an extension.
The router or router is more comprehensive, since it makes their times of DHCP. This is very useful if your ISP gives you only 2 teams to the Internet: with the router or router can connect as many teams want even if it only has 3 inputs can add a switch and connect more computers. Everything will depend on the router, on occasions since, according to network traffic they collapse and must be reset.
What's firewall is configured, one need only learn basic knowledge on the subject. Go to the settings and you give out to the port of the IP you need and that's it.
To free up a port, you must enter the settings of your router. To enter these settings only to start a Web browser and enter the gateway through which communicates your computer to the Internet and you get something like this: d-link emulator.
Sincerely, if in doubt ask again or look at Wikipedia.
