About Routers

A router is a networking device that allows the transfer of data between computers. In the end user world, routers are the hardware piece that enables the connection of two or more computers. This allows multiple computers to share common resources--namely printers and Internet connectivity. Routers can be as simple as the device supplied by your ISP (Internet Service Provider), or the extremely complex switches that keep the World Wide Web running smoothly and efficiently.

Features

A look at a simple SOHO (Small Office/Home Office) router will more or less help the lay user understand how this technology works in a real-world scenario. A typical router has five RJ-45 jacks in the back--one is to connect to the modem (usually cable or DSL), and the other connects to other nodes (PCs or printers) on the network. If the router has wireless capability, then users with wireless-enabled computers (virtually every modern laptop) are able to connect without being physically tethered to the router.

Benefits

Routers used in a commercial world offer many benefits. Not only by supporting networking, they also handle all the data running around the Internet, and control traffic on (as well as in and out) the company's network. Routers also can redirect data traffic in the event of an outage or bottleneck in the World Wide Web.

The Facts

Routers (SOHO routers are sometimes called a gateway or a residential gateway) are usually combined with a DSL or cable modem. They have built-in firewalls, to give users an extra layer of protection from hackers. Routers can also be configured to limit both the type and amount of data traffic in and out, what applications can be used to access data, and what users are allowed what privileges.

Function

A typical router is used to connect a LAN (local area network) to the Internet. It can be set up to distribute IP numbers (also known as Dynamic IP addresses) or to allow each PC to be configured to use a predetermined IP address (also known as Static IP address). Routers also have the ability to store the phone number, username and password required for DSL (Digital Subscriber Line).

Risk Factors

One risk factor that SOHO users face is the threat of intruders. While most routers contain various degrees of security features, the sad fact is that many users tend to install the routers with their default settings untouched. Therefore, the typical logon to configure the router (User Name: admin, Password: admin) will allow slightly tech-savvy users to hack into your network. Furthermore, if no wireless password is provided, anybody with a laptop who happens to be within range of your network is a threat to hack in.
