Routers, To See Different Types of Routers

There are several types of routers you may hear of: wired router, wireless

router.

More detailed classification: Internal router (IR): All interfaces belong to

the same area; Area Border router (ABR): Interfaces to multiple areas;

Backbone router (BR): Interfaces to backbone; Autonomous system

boundary router (ASBR): Exchange routing info with other autonomous

systems; Designated router (DR): Generates link-state info about the

subnet; Backup designated router (BDR): Becomes DR if DR fails.

If you use computers in your home or office, it is likely that your

computer is connected with other computers through some type of

router. Like a police officer directing traffic at an interchange, a router

will direct or route information, data and files to the locations they need

to go. Generally, Routers that we used can either be wired or wireless.

A wired router will generally connect to your computer and computers

or hardware through an Ethernet cable. This happens with the use of

output ports. And the only input port provided on a router will be used

for the Internet.

A wireless router may allow access from several computers through

wired Ethernet cables and through wireless connections. You will know

the router you are using is wireless if it comes with an antenna. The

antenna will provide the router with a specific range that allows other

computers in the area with wireless capabilities to access the router,

provided they have password access.

Two Typical Routers We Usually Used

Commercial Router

If you have ever been to a coffee shop or hotel that offers Wi-Fi access,

chances are they are using a commercial-grade router. These routers are

much more powerful than what you would purchase at your local

electronics or computer store. The best commercial routers will be able

to provide access to the Internet, files and printing, for example, with

little problem. Commercial routers may also be used by businesses,

hospitals or in a university setting as part of a wide area network or

WAN. (Cisco is a leading router manufacturer to aim to provide router

and networking solution to small, medium and large enterprises) This is a

network that allows computers to connect to each other even if they are

in another building across town. The commercial-grade router will be

used to connect with the wide area network (WAN) on one side and a

smaller network called a local area network (LAN) on the other. The local

area network may consist of one large office within a building. In that

case, you could have multiple LANs connecting to the WAN through one

or multiple routers.

Consumer Routers

If you are looking for a router for your home or small business, you likely

can find what you need at your local electronics store. Generally you will

want a router that serves as a wireless access point (WAP). It should also

be a network switch. The wireless access point (WAP) basically provides

the wireless access that everyone wants. That wireless access can be

both to the Internet and to other computers in the home or office.

Routers that come with a network switch tend to be faster and provide

more evenly distributed bandwidth to each port. Consumer routers will

come in a variety of price ranges and strengths. Some of the lower priced

consumer routers will not have a very strong firewall. (Cisco Linksys E-

series routers, powerful home routers, are welcomed by a lot of Cisco

fans, more info of Cisco’ home product store you can visit Cisco’s official
