Types of router
There are three types of routers in the market. These types are the main categories.
(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.
(3) Other Types of Routers
Ⅰ. Edge Routers
This type of router is placed at the edge of the ISP network, that is normally configured to external protocol like BGP (Border gateway protocol) to another BGP of other ISP or large organization.
Ⅱ. Subscriber Edge Routers
This type of router belongs to an end user (enterprise) organization. It’s configured to broadcast external BGP to its provider’s AS(s)
Ⅲ. Inter-provider Border Routers
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.
Ⅳ. Core Routers
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 bandwidth.
Ⅴ. 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.
DIFFERENCES OF MODEM & ROUTER
MODEM
The modem connects to a cable/wire from the outside, bringing in Internet data (email, You Tube videos, Google search results, files) from all over the world. A different wire that goes from your modem to your computer delivers your Internet requests and activity to your computer and monitor. What you see is what you asked for. Thanks, modem!
In case you’re wondering, you can’t simply plug that cable from your Internet Service Provider directly into your computer. It just doesn’t work that way. You NEED that modem between the cable and your computer. No modem, no Internet.
You could go online using just your modem and computer, but there’s a reason to think twice. Modems are useful, but they are not smart pieces of hardware. They can’t do much when it comes to providing Internet safety, like keeping hackers away. Also, one modem connects to only one computer.
So with just a modem, your computer is at risk. You’ll need to rely on special computer software (anti-virus programs, etc.) to fight of bad stuff coming in from online (computer viruses and such). And make no doubt, there’s plenty of that out there.
Enter the router, a good companion for your modem, your computer and you. With a few wires and connections and installing some software, you’re modem, router and computer get connected.
ROUTER
A router does two special things by leeching on to your modem. (Well, three.)
It can take the digital signal from your modem (which the modem gets from the cable company’s cable) and share it with (route it to) other computers in the house. You now have a computer network at home.
In order to do this, the router monkeys with and modifies the IP address on your computer(s). Just by doing that, it automatically makes it hard for hackers to now get at your computer. In fact, it’s harder to target any specific computer linked to the router.
A wireless router allows you to connect your Internet connection at home with any wireless device, such as a laptop, Smartphone or iPad. (Make a note: you just need to make sure your wireless network is secure. That information comes with the router.)
