Computer Fundamentals - Routers VS. Modems - What is the Difference Between a Router and a Modem? PC

They typically come with a port that connects to modems to communicate with the Internet. Routers can also connect wirelessly to devices that support the same wireless standards. Wireless routers can receive information from and send information to the Internet. Routing is the ability to forward IP packets—a package of data with an Internet protocol IP address—from one network to another. The router's job is to connect the networks in your business and manage traffic within these networks.

Routers typically have at least two network interface cards, or NICs, that allow the router to connect to other networks. Routers figure out the fastest data path between devices connected on a network, and then send data along these paths. To do this, routers use what's called a "metric value," or preference number. If a router has the choice of two routes to the same location, it will choose the path with the lowest metric. The metrics are stored in a routing table. A routing table, which is stored on your router, is a list of all possible paths in your network. When routers receive IP packets that need to be forwarded somewhere else in the network, the router looks at the packet's destination IP address and then searches for the routing information in the routing table.

If you are managing a network, you need to become familiar with routing tables since they'll help you troubleshoot networking issues. For example, if you understand the structure and lookup process of routing tables, you should be able to diagnose any routing table issue, regardless of your level of familiarity with a particular routing protocol. As an example, you might notice that the routing table has all the routes you expect to see, yet packet forwarding is not working as well as expected.

By knowing how to look up a packet's destination IP address, you can determine if the packet is being forwarded, why the packet is being sent elsewhere, or whether the packet has been discarded. When you need to make changes to your network's routing options, you log in to your router to access its software. For example, you can log in to the router to change login passwords, encrypt the network, create port forwarding rules, or update the router's firmware. Routers help give employees access to business applications and therefore improve productivity—especially for employees who work remotely or outside main offices. With routers in place, your business can improve responses to customers and enable easier access to customer information.

These are real benefits at a time when customers demand fast answers to questions, as well as personalized service. By using routers to build a fast and reliable small business network, employees are better able to respond rapidly and intelligently to customer needs. Routers can have a positive impact on your bottom line. Your small business can save money by sharing equipment such as printers and servers, as well as services such as Internet access. A fast and reliable network built with routers can also grow with your business, so you don't have to keep rebuilding the network and buying new devices as the business expands.

Although how routers work is pretty basic, when it comes to actually troubleshooting problems with them, there are hundreds, maybe even thousands of different answers that might be the right one for you. All that said, wireless routers are a constantly evolving set of devices, and the manufacturers who make them are always finding new and exciting ways to innovate on the year old technology.
