The Primary Differences Between Hubs and Switches

Both hubs and switches are useful devices for expanding your network's capability. While they are quite similar, hubs and switches have a fundamental difference that makes switches more useful to optimize your network.

What is a switch?

A switch is a small hardware device that splits a local area network, or LAN connection into multiple LAN connections. Think of it as a power strip for broadband Internet since it turns one live connection into several. Switches cannot convert wide area network, or WAN connections into LAN connections. They are limited to operating within the LAN portion of the network. In addition, switches have internal processing that allows them to identify the sender and receiver of a data packet. Since switches can prioritize packets and send them only where needed, they improve the network's overall performance.

What is a hub?

A hub serves the exact same function as a network switch. Hubs take a LAN connection and convert it into multiple LAN connections. However, hubs lack the capability to identify and prioritize packets, hindering network performance when compared to switches.

How many Ethernet ports can be added through hubs and switches?

Each individual hub or switch often has from four to eight ports, depending on the price point. However, the maximal capability you can add through hubs and switches is limited only by the serving capacity of the router. You can "daisy-chain" switches and hubs to add as many ports as you require.

Which is more expensive, a hub or a switch?

Hubs are typically cheaper than switches since switches have the added capability of data packet management. For your network, choose a hub if you're on a budget and need only LAN-splitting capability. Choose a switch if you're looking to maintain your network's maximal speed over several LAN ports.

Hubs and switches provide an easy way to expand the LAN ports in your network. Switches are higher priced, but they provide a solid way to maintain your network's performance thanks to packet management. For those on a budget, hubs split your LAN in reliable fashion.

Operating Your Wireless Router on a Standard Channel

Most modern wireless router standards for Wi-Fi assume that the router uses the standard 2.4-Ghz band for data transmission. Unfortunately, the proliferation of wireless devices has caused the 2.4-Ghz band to become extremely crowded in many places where competing networks and devices are common. This causes your wireless network to be slow or to drop data and connections. While the newer dual-band wireless router solutions offer a way to use the less common 5-Ghz band to work around these issues, there are still some tricks that help keep your 2.4-Ghz network running at the best possible speed.

DO: Place your router as centrally as possible

Wireless signals decay with distance, so it's important to make sure your router is as central as possible to the area where you use your network. This helps insure that your router is the strongest signal source in the area and your signal is subject to the minimum of interference.

DO: Use a wireless bridge or repeater to extend your signal

Sometimes it's not possible to be close enough to the router to eliminate interference due to architectural concerns or simple distance. In this case, a wireless repeater or bridge boosts the signal in these areas and helps keep your network available. This is a great way to re-use an older router if you have recently upgraded or have one handy. Most routers are configurable to operate in a repeater mode for exactly this purpose.

DON'T: Leave your network unsecured

Unsecured networks are sometimes slower than secured networks due to either other devices accidentally attaching to the network or other people deliberately taking advantage of the free access point. Securing your network with a password both prevents many privacy and security concerns and keeps unauthorized devices from taking your bandwidth and crowding your network.

DON'T: Use an outdated wireless standard

Virtually all wireless routers implement some version of the 802.11 wireless router standards. Newer versions like 802.11g, 802.11n and 802.11ac sometimes see considerable performance and stability boosts even in the standard 2.4-Ghz channel. Make sure both your router and any communicating devices are using the latest version of this standard that they support. You typically are able to set your router to the latest possible standard as the standards are backward-compatible, except to much older devices.

Operating your router on the standard 2.4-Ghz frequency is sometimes frustrating in places with a lot of interference or where there are many competing networks. In some cases, nothing other than a switch to a dual-band device helps. However, keeping your router optimally placed and supported by bridges and repeaters makes a considerable difference, as does securing your network and making certain your devices are using the latest 802.11 standards.

Networking 101: Router Versus Switch

Switches and routers are basic components of networking that work to connect a series of computers and other devices on a network. Routers and switches connect different devices and let them communicate with each other. They are used in small to large sized businesses, schools and other organizations. Learn about the advantages and disadvantages of each option to see when each one is appropriate to use. Compare router vs switch pros and cons to expand your networking knowledge.

What are the advantages of using a router?

Routers are used to connect networks to other networks. Routers are advantageous when a company or organization wants to connect multiple preexistent networks to increase the productivity of its workers and expedite the data transfer process. A router sends out packages through the network until it reaches its desired destination. This makes it easy for the package to arrive at the proper place because each package includes the IP address of the destination device.

What are the disadvantages of using a router?

Several routers create transmission delays since more calculations are required to put together the packages. Routers also require more expertise to setup and use. Routers are typically used when you have several large networks to connect. They are best setup by a seasoned professional. A router is also expensive.

What are the advantages of using a switch?

A switch keeps MAC address records of all the connected devices. This minimizes network response times because it knows exactly where to send a frame when it is received. The switch knows where every device is located, making it quicker and easier to transmit data. A switch is also beneficial for high bandwidth usage. Every user receives the maximum amount of bandwidth regardless of the amount of PCs transmitting data throughout the network.

What are the disadvantages of using a switch?

A switch is only used for connecting a wired network, meaning that you are not able to connect multiple computers over a wireless signal. This limits the amount of uses for a network switch. It connects to networks that are wired to the wall, as opposed to computers that are connected through a Wi-Fi signal. This works well for companies or organizations that do not use wireless connections, but it limits companies that connect through a wireless signal or want to connect multiple networks.

The router vs switch comparison is important for setting up a proper network connection. Use these tips to decide whether a router or switch is best for your organization. Several organizations use both routers and switches to maximize worker productivity and network efficiency.

Networking 101: Router Setup Basics

Setting up a router is easy if you understand the key connection between the router and your home network. Easily set up a router in minutes but take the additional time to customize some important settings.

What is the connection between a router and a modem?

A modem translates the commercial signal from your Internet service provider (ISP) into a residential Internet signal. The modem makes it possible for your router to take an ISP address in the wide area network (WAN) and use it to manage a local area network (LAN). With just a modem, you can only connect one device at a time. A router is a DHCP server that dynamically assigns IP addresses to your devices, connecting them all to the WAN of the Internet simultaneously.

How are router settings accessed?

Some newer routers come with software that makes router access easy. Linksys, for instance, now comes with Cisco Connect software that makes it a little more user-friendly to customize your router. For all routers old and new, use a web browser to access the router through its default IP address. For most routers, this is either 192.168.1.1 or 192.168.0.1.

What functionality is provided by a router?

A router is a converged device that provides the services of a wireless access point, DHCP server and network switch. Some routers have USB ports for network storage and dual bands for more powerful wireless networking. Most routers have a suite of security settings, such as encryption and a firewall.

What are some key security settings in the wireless router?

The first thing to do when your router is connected is make sure your network is secure. In the wireless networking settings, set an encryption and choose a strong wireless password. Make sure the firewall is active, and change the default administrator username and password information.

Router setup is a basic part of home networking. Even if you have to take the time to learn a few key concepts, it is worth it because a router offers so much flexibility and customization to your entire network, keeping it safe, secure and connected.

Connecting Switches and Routers in a Home Network

Switches and routers expand your ability to hardwire devices in your home network. While a router has the capability of a network switch, it only provides limited expansion and you easily add switches to create additional ports.

Connect the router

The router serves as the brains of your network. Since routers provide dynamic IP addresses for all of your devices, you want the router at the head of the network. Connect it directly to your modem using an Ethernet cable.

Power up the router

Plug in the router, and give it a few minutes to warm up and initialize. During this time, it collects your IP address from your broadband service. You only get one IP address from most broadband providers, but having a router assign other IP addresses allows you to simultaneously connect several devices.

Calculate your network needs

Count up how many devices you need to hardwire with Ethernet cables. A router usually gives you four additional ports. You get to purchase switches with a variety of capacities, including small, four-port switches or larger, consumer-grade switches with 64 jacks.

Choose the correct switch layout

Now that you know how many devices you need to accommodate, get switches that accommodate the layout. Just because you need 16 jacks doesn't mean you need a 16-port switch. You possibly get more convenience if you purchase two switches with eight ports each and locate them in different areas of your network.

Connect the switch to the router

Use an Ethernet cable to connect a vacant port from the back of the router to a vacant port on the switch. It doesn't matter which port you use on the switch, but you possibly have an easier time remembering which cable leads to the router if you use the first port. You are able to connect more than one switch to the router and you also are able to connect a switch to another switch, as long as the original switch is connected to the router.

Plug your devices into the switches

With a connection made from the router to the switch, all of the switch ports are now live and ready for connectivity. Use Ethernet cables to connect all of your computers, laptops, media streamers, televisions or other devices with available Ethernet jacks. Your network is now complete.

Switches allow for the simple expansion of network capability, but they don't manage or assign IP addresses. A router handles IP address management along with many other functions, but the right combination of switches and routers adds Ethernet ports to your home network quickly and easily.

Understanding the Differences Between a Switch vs a Router

Switches and routers are important hardware components of an effective home network. You may think they provide similar functionality, but technologically, they have stark differences that make it important to understand the features switches and routers provide.

What is a network switch?

A switch is a network device that connects multiple computers over a local area network (LAN). The best way to understand a network switch is to compare it to a power strip; a power strip turns one live electrical outlet into several live electrical outlets so you can connect multiple power-hungry devices. Functionally, network switches work similarly, but they "split" a live Internet connection instead of power. Switches are important to expand the capability of your network. Your Internet service provider only provides one access point to a wide area network (WAN). When this point is funneled properly through a modem, a network switch can turn that single access point into the capability you need for multiple devices.

What is a router?

A router is a multi-function device that combines the capability of a switch, a wireless access point, a router and sometimes a modem. Routers prioritize packets to optimize network performance and provide multiple Ethernet ports, serving as a switch. A router also turns a WAN point into a wireless network in your home. Some routers even serve as modems.

How does a switch compare to a router?

A router is a far more versatile and sophisticated device. In fact, a router replaces the need for a network switch in many homes, since it typically provides the function of a switch along with its other features. While a switch merely splits the LAN connection, a router provides prioritized traffic, splitting functionality and wireless network conversion.

Does a router completely replace the need for a switch?

In some cases, a switch and a router complement each other on the same network. Assuming you have a lot of network devices that require Ethernet connectivity, the three to four ports provided on the back of a router might not meet your needs. In these cases, you can connect a network switch to one of the LAN ports in the back of the router, adding even more total LAN ports to your network. Daisy-chaining these devices expands your capability.

When you compare a router versus a switch, you find that a router is a far more complex and useful device while a switch provides a more specific function for the expansion of LAN-based networks. If you are looking for the more diverse, advanced device, opt for a router.

What is the difference between a router and a switch?

A switch sorts and distributes the network packets sent between the devices on a local area network (LAN), while a router is a gateway that connects two or more networks, which can be any combination of LANs, wide area networks (WAN), or the Internet. In addition, a router uses tables to determine the best path to use to distribute the network packets it receives, and a protocol such as ICMP to communicate with other routers. A router is a significantly more complicated device than a switch--essentially a specialized computer--and more advanced models may use a reconfigurable operating system such as Linux, rather than firmware coded directly into the hardware. Both routers and switches operate on layers 2 and 3 of the OSI model.

In an enterprise environment, routers and switches are separate physical devices dedicated to their specific tasks. However, typical "broadband routers" for the home and small office are actually multifunction devices that combine the capabilities of a router, a switch, and (usually) a firewall into one box. In addition to routing traffic between the Internet and the LAN, they also handle switching for packets between devices on the LAN, and often add additional features such as port forwarding and triggering, a DMZ, a DHCP server, a DNS proxy, and/or network address translation. In addition, "wi-fi routers" add a wireless access point.


Note: A hub is even simpler than a switch. Instead of inspecting the packets that it encounters and sending them to the correct destination device, it just forwards them to all connected devices.


In short, Router routes any traffic comes to it & Switch provides local services to local user's in LAN but some special Switches are out their that work for both LAN & WAN. They are much expensive and used by the big Organizations.

A router connects 2 separate networks (e.g. WAN and LAN)
A switch connects all network components (like computers, network printers, etc) within a network.
A switch does essentially what a hub does but more efficiently. By paying attention to the traffic that comes across it, it can "learn" where particular addresses are. For example, if it sees traffic from machine A coming in on port 2, it now knows that machine A is connected to that port and that traffic to machine A needs to only be sent to that port and not any of the others. The net result of using a switch over a hub is that most of the network traffic only goes where it needs to rather than to every port. On busy networks this can make the network significantly faster.
A router is the smartest and most complicated of the bunch. Routers come in all shapes and sizes from the small four-port broadband routers that are very popular right now to the large industrial strength devices that drive the internet itself. A simple way to think of a router is as a computer that can be programmed to understand, possibly manipulate, and route the data its being asked to handle. For example, broadband routers include the ability to "hide" computers behind a type of firewall which involves slightly modifying the packets of network traffic as they traverse the device. All routers include some kind of user interface for configuring how the router will treat traffic. The really large routers include the equivalent of a full-blown programming language to describe how they should operate as well as the ability to communicate with other routers to describe or determine the best way to get network traffic from point A to point B
Different router and different switches can all do different things. The dividing line between all these devices is getting very fine. However one major difference between a router and a switch is that a router has it's own IP address. This allows you to log into it.

Aswell as that most home routers have wireless capabilities (thats the only reason why most home users want them in the first place anyway).

Computer Networking

Routers and switches are both computer networking devices. They allow one or more computers to be connected to other computers, networked devices, or to other networks.
However, the functions of a hub, switch and router are quite different, even if at times they are integrated into a single device. Routers connect two or more logical subnets, which do not necessarily map one-to-one to the physical interfaces of the router. The term layer 3 switch often is used interchangeably with router, but switch is really a general term without a rigorous technical definition. In marketing usage, it is generally optimized for Ethernet LAN interfaces and may not have other physical interface types.
