Router and Switches free essay sample

Router and Switches II In Routers and Switches we learned several things such as: what is a Router, why we need Routers, what is the importance of a Router. We also learned what VLSM is and how to do it and use it. Throughout CCNA we learned how to configure a Router; the different types of Routing protocols and most importantly what, when and how to use those protocols in the field. Finally I will discuss Switches in how they are use to set up a LAN. Throughout this paper these topic will be discuss to cover what was learned through class lecture and text book (CCNA study guide by Lammle) and actually applied through hands on labs which were done with actual Cisco Router and Switches within a working LAN and Ethernet connection environment. What is a Router? According to tech-faq. com â€Å"a router is a network device with interfaces in multiple networks whose task is to copy packets from one network to another†. We will write a custom essay sample on Router and Switches or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page CCNA Study Guide defines it as â€Å"a network layer mechanism, either software or hardware, using one or more metric to decide on the best path to use for transmission of network traffic. Sending packets between networks by routers is based on the information provide on network layers. Historically, the device has sometimes been called a gateway. † The best way to understand what a router is would be to understand its purpose which is to direct or send information packet from one network to another whether it be LAN or WAN. We must also understand that though it has other function this is more of what a router does and interns makes a router what it is. Let’s look at the Importance of a router. How important is a router. Well let’s start off by asking this question, what would happen if there was no routers? How would we connect outside of our network range not to mention within in our LAN that is broken in to small network if we did not have them? Without routers we could only communicate with nodes within our range if we are a class A then within that range we can communicate, since there is no router that hold information pertaining to any class B address A cannot talk to them it does not know how to reach them. So without routers we cannot communicate to other classes just our Class A network (our private network) thus leaving the network no communication with other networks.
