There are several types of routers you may hear of

• 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.

Why you need those two types routers

• 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.
