People want to be able to share a single broadband Internet connection to several computers in the house. There are many different devices that you can use to make up your home network. If you have never heard network terminology device names likerouter, hub, etc may seem confusing.

The purpose of most of these devices is to control how the network passes around information. This information is sent in the form of “packets”. I will refer to the term packet several times in this article. It simply means the data that the network is transporting. I will now explain the purpose of the major components of a home network.

What is a Hub

A hub is a device that has several Ethernet ports on the back of the device. One of these ports will likely be labeled “Uplink”. This port allows you to connect multiple hubs together, if you run out of ports on your hub. If you do not have an uplink port on your hub, the hub cannot be easily extended if you run out of ports.

A hub is a device that attaches multiple computers on an Ethernet network. If you have a number different computers that you want to connect together, you could connect each to the hub. Any packet that is sent out by any computer on the network will immediately be transmitted to the other computers. Each computer will determine if the packet was really intended for it, and filter out packets that were intended for other computers.

You really should not use a hub in a modern home network. You should always use a switch in place of a hub. Switches will be discussed in the next section.

What is a Switch

A switch is a device that has several Ethernet ports on the back of the device. One of these ports will likely be labeled “Uplink”. This port allows you to connect multiple switches together, if you run out of ports on your switch. If you do not have an uplink port on your switch, the switch cannot be easily extended if you run out of ports.

A switch serves the same function as a hub. It allows you to connect multiple computers together, so that they can exchange packets. However, a switch is much more efficient than a hub. A switch will only send Ethernet packets to the computer that the packet was intended for. Because of this you should always use a switch in place of a hub.

What is a Router

A router is a device that has several Ethernet ports on the back of the device. One of the connectors will be labeled WAN. You should connect the WAN port to the Ethernet connection on a broadband source, such as a cable or DSL modem. The other ports on the router can be connected other computers or switches/hubs that will share the WAN connection.

Routers allow you to share your broadband connection with multiple computers in your house. Rather than connecting your computer directly into your cable or DSL modem you connect the router to the cable or DSL modem. Now any computer that you connect to the router will have access to the Internet.

If you run out of ports on your router you can always connect an additional switch to the router. To connect a switch to a router simply connects the switch’s “uplink” port to one of the routers Ethernet ports. Of course, don’t connect to the router’s WAN port. The WAN port should only be connected to something such as a cable or DSL router.

Some routers come with additional features installed. Most routers also include a firewall. Firewalls are discussed in the next section. Some routers will also include a wireless access point (WAP). The WAP allows you to use wireless devices, such as wireless laptops, with the Internet.

What is a Firewall

A firewall controls traffic flow between your network and the Internet. A firewall can be either hardware or software. Windows XP SP2 or higher includes a software firewall. A hardware firewall is included with most routers.

A firewall is a very good idea. It can protect you from inbound virus attempts. By inbound virus attempt I mean other computers that will connect to your computer and attempt to infect your computer. You do not want to run a computer directly connected to the Internet, without a firewall. There are just too many other computers out there that can connect and infect you without you even noticing.

What is a Network Attached Storage (NAS)

A network attached storage device is s device that allows a hard drive to be shared across the network. This hard drive is NOT attached to any of your computers. It is simply made available by the NAS. This can be a convent way to add a hard drive that can be accessed by several computers on your network. The other common way to add a network hard drive is to simply share a folder on one of your computers. However, with the NAS, you do not need to keep one of your computers on at all times.

There are two types of NAS commonly available. The first type comes with a build in hard drive. The second accepts a USB or Fire wire external hard drive. The advantage to using a USB or Fire wire hard drive is that you can upgrade the hard drive if it ever were to become too small.

What is a Print Server

Just like you can buy a device to allow you to share a hard drive, you can do the same with a printer. A print server connects directly to your printer. Your printer is then shared to all of your computers on the network. This is convent because you do not need to leave the printer hooked to a computer, which must be turned on to print.

Conclusions

As you can see there are many different components. Perhaps the final component that I ave yet to mention is the cable. These components are connected together with CAT5 Ethernet cable .

The differences between hubs, routers, Internet Connection Sharing (ICS) and cabling were a mystery to me. But after much trial and error and built-up experience I managed to figure things out and some of that information I will share with you now.

There are two basic types of networks that I’m going to talk about in this article first being the infamous ICS or Internet Connection Sharing. ICS is usually implemented by connecting multiple computers through the hub to a single computer. Let’s say we have three computers, Computer A, Computer B and Computer C. Computer A has enjoyed a high speed Internet connection and after a while, Computer B and C want to get in on the action! In order to implement ICS, we would have to connect Computers B and C to a hub.

A hub is basically a switch that allows any computer hooked up to it to communicate with any other computer hooked up to the hub. So with all three computers hooked up to it, we would set the network up on the computers to use ICS. Computers B and C would be told that they’re going to connect to the Internet through another computer that has a high-speed Internet connection. While Computer A would be configured to enjoy its high-speed connection as it did before.

Like this, Computers B and C would enjoy a relatively fast connection to the Internet as would Computer A. The problem here starts when all three computers are accessing the Internet at the same time. Computers B and C would enjoy a relatively fast connection to the Internet while Computer A would suffer some moderate slowdowns because it not only has to handle its own traffic but the traffic of the other two computers as well. The user on Computer A is going to get quite upset if Computers B and C decide to download files at the same time. Because downloading a file is such a data intensive process, demanding large amounts of data be transferred from the Internet as fast as possible, Computers A may suffer some severe speed problems because of the demand being put on it from the other two computers.

Unfortunately because of the fact that the hub does not have built-in firewall or any other such software that can protect the computers behind the hub Computers A must also be running Windows firewall in the background which provides an additional performance hit.

So although the ICS is the cheapest way to go, it is definitely not the speediest way to go. In fact, to be honest, I would only follow this route if the users of Computers B and C had something against the user of Computer A and want to get even!

The second type of setup that I’m going to talk about it is the router based set up. Nice thing about the router is that most routers are very intelligent. They have built-in firewalls, parental controls, can block sites or even allow users to have access to your network from the outside if they know the proper passwords and/or ports to connect through. No additional software is required that might add a performance hit and all three computers get configured the same way.

To hook up or router you simply plug a cable from your Internet connection into the router then plug the three computers into the router as well. When you set up your computers you tell networking software that all three will computers have direct access to the Internet. There is some setup involved with router as is usual with any complicated piece of hardware but usually it is very painless and if you follow the instructions, quite easy!

The nice thing about router set up is that once it is set, up all three computers enjoy the same speed advantages of being on a high-speed Internet. No one computer is impacted by the fact that someone else is downloading a file. In fact, all three can download a file at the same time and still enjoy impressive speed while doing so! Face it guys this is the network that you want to set up if your wife is on Computer A!

Routers tend to be a little more expensive than hubs but the advantages of having them a part your network far outweigh any price difference. So if you must go with ICS, then do so with pride! But personally, I would recommend spending the extra money to go the “router route”!
