Types of Routers
What is a Router?
Before we delve into the world of routers, you need to understand what a broadband connection is and how it works. According to Dictionary.com, broadband is "a high-speed, high-capacity transmission medium that can carry signals from multiple independent network carriers. This is done on a single coaxial or fiber-optic cable by establishing different bandwidth channels. Broadband technology can support a wide range of frequencies. It is used to transmit data, voice and video over long distances simultaneously."
Routers take information that arrives through your broadband signal via a modem, decipher it, and deliver it to your computer. The router will also choose the best route for the data packet so that you receive the information quickly.
Many different types of routers have been developed so that the information coming over your broadband connection can be sent to a variety of different receivers including your computer, your phone, and others.
Types of Routers
There are several types of routers in the market.
1 Broadband Routers
Broadband routers can do different types of things. Broadband routers can be used to connect computers or to connect to the Internet.
If you connect to the internet through phone and using Voice over IP technology (VOIP) then you need broadband router. These are often a special type of modem (ADSL) that will have both Ethernet and phone jacks.

2 Wireless Routers
Wireless routers create a wireless signal in your home or office. So, any PC within range of Wireless routers can connect it and use your Internet.
In order to secure your Wireless routers, you simply need to come secure it with password or get your IP address. Then, you'll log on into your router with the user ID and passwords will that come with your router.
Other Type of Router
1 Edge Router
This type of router are placed at the edge of the ISP network, the are normally configured to external protocol like BGP (Border gateway protocol) to another BGP of other ISP or large organisation.
Subscriber Edge Router
This type of router belongs to an end user (enterprise) organization. It’s configured to broadcast external BGP to it’s provider’s AS(s)
Inter-provider Border Router
This type of router is for Interconnecting ISPs, this is a BGP speaking router that maintains BGP sessions with other BGP speaking routers in other providers' ASes.
2 Core Router
A router that resides within the middle or backbone of the LAN network rather than at its periphery. In some instances , a core router provides a stepdown backbone , interconnecting the distribution routers from multiple building of a campus ( LAN), or Large enterprise Location (WAN). They tend to be optimized for a high brandwidth.
3 Wired and Wireless Routers.
Home and small office networking is becoming popular by day by the use of IP wired and wireless router.Wired and wireless router are able to maintain routing and configuration information in their routing table. They also provide the service of filtering traffic of incoming and outgoing packets based on IP addresses. Some wireless routers combines the functions of router with those of a network switch and that of a firewall in one.
