What do you know about router ?

Hi everyone, on today we will learn about routers in simplified terms to prepare and understand for cert exams.

In simple, and also in technical terms to discuss about Router; 

• Routers are small electronic devices that join multiple computer networks together i.e., either wired or wireless connections.
• A router is a Layer 3 network gateway device, meaning that it connects two or more networks and that the router operates at the network layer of the OSI model.
• Routers contain a processor (CPU), several kinds of digital memory, and input-output (I/O) interfaces. 
• They function as special-purpose computers, one that does not require a keyboard or display.

For Example : In general, suppose when you search for www.google.com in your web browser then this will be a request which will be sent from your system to the google's server to serve that web page, now your request which is nothing but a stream of packets don`t just go the google's server straightaway they go through a series of networking devices known as router which accepts this packets and forwards them to correct path. Hence, it reaches to the destination server.
