The Differences Between Routers, Switches, and Hubs

Nov 04,  · Routers for home networks (often called broadband routers) are designed specifically to join the home network to the Internet for the purpose of Internet connection sharing. In contrast, switches (and hubs) are not capable of joining multiple networks or sharing an Internet connection. Routers and switches are both computer networking devices that allow one or more computers to be connected to other computers, networked devices, or to other networks. The functions of a router, switch and hub and are all different, even if at times they are integrated into a single device.

Learn how routers securely connect your small business to the rest of the world and connect your devices, including laptops and printers, to each other. Our world is facing an acceleration in the frequency, diversity, and impact of disruptions. Planning your network to help your organization respond to the unexpected is now more important than ever. When building a small office network, the two most essential pieces of equipment you will need are switches and routers.

Though they look similar, the two devices perform different functions within a network. Switches facilitate the sharing of resources by connecting together all the devices, including computers, printers, and servers, in a small business network. Thanks to the switch, these connected devices can share information and talk to each other, regardless of where they are in a building or on a campus. Building a small business network is not possible without switches to tie devices together.

Just as a switch connects multiple devices to create a network, a router connects multiple switches, and their respective networks, to how to use panasonic lumix lx7 an even larger network. These networks may be in a single location or across multiple locations. When building a small business network, you will need one or more routers.

In addition to connecting multiple networks together, the router also allows networked devices and multiple users to access the Internet. Ultimately, a router works as a dispatcher, directing traffic and choosing the most efficient route for information, in the form of data packets, to travel across a network. A router connects your business to the world, protects information from security threats, and even decides which devices have priority over others.

Understanding Home Networking Through Network Diagrams

Router and switch both are the connecting devices in networking. A router is used to choose the smallest path for a packet to reach its destination. A switch stores the arrived packet, process it to determine its destination address and forwards the packet to a specific destination. A router is a device that is used to interconnect various switches of different networks to form even a wider network. Routers are not the same as switches because their function is routing a packet from one network to the other network.

Read on to get a clearer picture of what you need to optimize your home network. When do you need a switch? A hub? What exactly does a router do? Do you need a router if you have a single computer? Network technology can be quite an arcane area of study but armed with the right terms and a general overview of how devices function on your home network you can deploy your network with confidence.

This user cannot access the internet with a Wi-Fi device thus no access for smart phones, tablets, or other wireless devices and they lose out on the benefits of having a router between their computer and the greater internet. When should you use a router? Given the low cost of home routers and the benefits gained from installing one on your network you should always use a router which almost always includes a firewall feature. Home routers are actually a a combination of three networking components: a router, a firewall, and a switch.

In a commercial setting the three pieces of hardware are kept separate but consumer routers are almost always a combination of both the routing and switching components with a firewall added in for good measure.

At the most basic level a router links two networks together, the network within your home however big or small and the network outside your home in this case, the Internet. The broadband modem provided to you by your ISP is only suited to linking a single computer to the internet and usually does not include any sort of routing or switch functionality. A router performs the following functions:.

In addition to the inside-to-outside network functionality outlined above, home routers also act as a network switch. A network switch is a piece of hardware that facilitates communication between computers on an internal network.

Without the switching function the devices could talk through the router to the greater internet but not to each other—something as simple as copying an MP3 from your laptop to your desktop over the network would be impossible.

Most routers have four Ethernet ports which allow you to plug in four devices and have them communicate via the switch function. If you only have one computer and one networked printer plugged into your four-port router and everything else on your network is Wi-Fi based there is no need to upgrade to gain physical ports. Although the four-port limit on the super majority of home routers was more than enough for most home users, the last 10 years have brought a significant increase in the number of networkable devices within the home.

As a side note, historically people often relied on hubs because they were so much cheaper than pricey switches. Because hubs have no management component there are frequent collisions between packets which leads to an overall decrease in performance.

Hubs suffer from a number of technical shortcomings which you can read about here. Consumer grade networks switches have fallen in price so steeply over the last 10 years that very few hubs are even manufactured anymore Netgear, one of the largest manufacturers of consumer hubs, no longer even makes them.

Because of the shortcomings of network hubs and the low prices of quality consumer-grade network switches we cannot recommend using a hub. Returning to the topic of switches: switches are an excellent and inexpensive way to increase the size of your home network. If you outgrow the bank of four ports on the back of your router the simplest thing you can do to expand your network is to purchase a switch with an appropriate number of ports.

Unplug the devices from your router, plug all the devices into the switch, and then plug the switch into the router. Note: switches have absolutely no routing functionality and cannot take the place of a router. Your router likely has a four-port switch built into it but that does not mean your new eight-port dedicated switch can replace your router—you still need the router to mediate between your modem and switch.

There are two primary designations we are interested in: Ethernet and Wi-Fi. Ethernet connection speeds are designated in 10BASE. In order to take full advantage of the maximum speeds all the devices in the transfer chain need to be at or above the speed rating you want.

In this situation upgrading the switch would boost your network performance considerably. Outside of transferring large files and streaming HD video content across your home network there is little need to go out and upgrade all your equipment to Gigabit. Wi-Fi speeds are designated by letter, not by number. Unlike the easy to translate number-as-network-speed designation we find with Ethernet the Wi-Fi designations actually refer to the draft versions of the IEEE Devices using How much faster?

There are some models that can do one gigabit per second. Like Ethernet, Wi-Fi speeds are limited by the weakest link in the direct network. If you have an In addition to the speed limitations there is a very pressing reason for abandoning the oldest popular Wi-Fi protocol You must use the same level of encryption on every device in your network and the encryption schemes available to Upgrading your Wi-Fi router and wireless equipment allows you to upgrade your wireless encryption as well as enjoy faster speeds.
