Essay title: Routers
Introduction
Welcome to the Routers section. Here we will analyse routers quite some depth; what they do and how they work. I point out to you that you should have some knowledge
on the OSI model and understand how data is sent across the network medium. If you find the information a bit too confusing or dont quite understand it, I would suggest you go back to the networking section and do some reading on the OSI model and Protocols.
You will find information on Cisco routers at the end of this page.
What are they and what do they do ?
Routers are very common today in every network area, this is mainly because every network these days connect to some other network, whether its the Internet or some other remote site. Routers get their name from what they do. which is route data from one network to another.
For example, if you had a company which had an office in Sydney and another one in Melbourne, then to connect the two you would use a leased line to which you would connect a router at each end. Any traffic which needs to travel from one site to another will be routed via the routers, while all the other unnecessary
traffic is filtered (blocked), thus saving you valuable bandwidth and money.
