If a packet is traveling to the LAN, the router bounces it back. The packet will be toured depending on the routing table if this is not the case. Hub A hub is a simple and cheap networking device that allows a bunch of computers to be connected to a single network When a hub receives a data packet an Ethernet frame from a network device at one of its ports, it broadcasts repeats the packet to all of its ports,i.
A collision occurs when two network devices on the same network try to send packets at the same time. Applications of each device Switch It is commonly used in local area networks for connecting many nodes. Forwards a message to a specific host - On each port, a switch, like a bridge, employs the same forwarding or filtering logic.
When a host or switch on the network transmits a message to another host or switches on the same network, the switch receives the frames and decodes them to read the physical MAC address component of the message. It manages traffic by forwarding data packets to their proper IP addresses. Traffic between these networks may be managed. It determines the best path to send packets. It is used for network monitoring.
They are also used in organizations to provide connectivity. It can be used to create a device that is available throughout the network. Modes of data transmission They define the direction in which data flows between two communicating devices. There are three types of transmission modes: Simplex - In this mode of transmission, data can only move to one direction i.
Half-Duplex - In this mode, only one device can send or receive data at a time but not both at the same time. Full-Duplex - In this mode, a device can send and receive data at the same time. Addresses used in each device A switch stores and uses the MAC address of a device to transfer data while a router uses the IP address of the device to transfer data between networks. Transmission of data A switch transmits data from one device to another in form of frames while a router transmits data from one network to another in form of packets.
A hub transmits data from one device to another in form of binary bits. Conclusion In this article, we have looked at hubs, switches, and routers. I hope the article has been of great assistance to you. This article was contributed by a student member of Section's Engineering Education Program. In doing so, it learns which devices are connected to which ports. Then, when a port receives a data packet, the switch reads its destination address and sends it directly to the intended device in the network instead of every single port.
As a result, a switch can greatly improve the speed of networks that receive a lot of traffic. Router A router is the most intelligent and complex of the three network connection devices listed in this article.
Rather than just forwarding data packets to other devices in a single network, routers are designed to forward data packets between two or more networks, as well as direct traffic between them.
There are two main types of integrated routers: wired e. Integrated routers are blurring the functional lines between routers, switches, and hubs.
But they are not the only devices doing so. As switches become smarter, they are taking on some of the tasks that used to require a router. Even hubs are becoming more intelligent. The Miller Group can help you sort through the many types of routers, switches, and hubs so that you can pick the best routing solution for your business. He started with The Miller Group in as a service technician and was promoted to Service Manager in Louis and the surrounding area.
What Is a Hub? What Is a Switch? What Is a Router? I have a leftover switch that I have placed at the end of a single cat 5 line going to the other end of my house. Essentially I am trying to use it as a spliter so I can put two computers at that end of a single cat 5 run.
There is a router on the other end of the house that connects to 3 other computers. Will the switch slow down the entire network or just the two computers that I connect directly to it and would I be better off putting the switch right below the router in and running new cat five to accomadate all the computers.
Well I think you would have to get a main router with 3 or more WAN ports for the internet connections one for each dsl line then connect the computers to the LAN lines. Need a little help on what to get. I am hooking up two seperate networks that will feed both audio and video I need to then hook up each network so that both can be viewed from two seperate locations.
Do I need to use a router or switch for each one or can I just use one to view both? There will be no Internet connection on either network but I am concerened about the integrity of each network. Has very little to do with the floors — it depends more on the number of computers and how much traffic you expect, and what kind.
Sounds like simple setup very much like that outlined in the article. Use a router to take in your internet, and then if you need to add more ports, use a switch as well, and you should be fine. Hi, I have a Lynksys broadband router that has the typical four LAN ports to connect four computers on the network.
Do I need to connect the routers with a crossover cable? I want to avoid doing things wirelessly, so any help would be appreciated. Watson: you really want either a hub or switch to extend your network when you already have a router. Both computers work fine with the Westell Wire- speed dsl modem by their selves…Is the Compaq too slow or is the Nic not going fast enough??
My guess would be that your older computer has a 10mb ethernet port, and that the hub only supports mb. I was thinking about connecting direct to the XBox. Can I just remove the XBox network adapter and hook it up direct , using my wireless Base Station as a straight router? I just want to get into some serious gaming, with a stronger ping. G not B. Based on your site, I think that one solution in this room is to plug a switch into the ethernet jack and plug the computer and a print server into the switch and the printers into the print server.
Sorry about the Garbled message earlier. Please ignore my attempt to graphically depict my arrangement. Will the arrangement I described work? I have a cable connection going into my modem which then goes into my Linksys wireless router.
I now realize that since I am only connecting to the Internet and nobody is connecting to me since I dont have a server or anything of the sort that I only need one IP address and that the router will dynamically issue IP addresses to all of the computers hooked up to my router.
The problem is that when we use my 3Com router through wired ports all three computers can access the Internet but when we use the Linksys wireless router we cannot access the Internet. I understand that the wireless device in this case hooked up to an xbox will be primary since it connects to the wireless port on the router first, and then all three of my computers that are hooked up to cable ports in the wireless router will draw 2nd, 3rd, and 4th.
What should I do to get all four devices connected to the Internet? My son really wants to use that xbox online but I am not able to get a cable to it so we must use the wireless for it and the cable for the three computers.
But, again, we have not been able to get online with the wireless router from any device when it is hooked up. Sorry for the long set-up and for jumping around so much but its late and Im tired.
Any help you can give me would be much appreciated. I still have all four IP addresses and my ISP says it is the routers fault because it should be assigning dynamic IP addresses and Linksys says I should get the static IP addresses from my ISP and enter them manually… in effect they are blaming each other…but maybe it is I that should be blamed??? Hi, first and foremost what a great site, but I have a question… I currently have a cable connection that is connected to a linksys wireless router.
The wireless router has a hub connected in the uplink port on the router. So, based on this configuration my questions are as follows. Is there a better configuration that I could use so that I can see all of my connections? And from time to time, i am getting slow response or disconnected from my wireless connections, is the configuration contributing to this? Thanks any help would be greatly appreciated! I am concerned that the hub is connected to the uplink port. That brings up a couple of other questions.
I had planned that the four computers would be connected to this service via a four port router. None of us wants to share what is on our computers. How can we block access to our individual computers? The second question has to do with the distance a signal can be carried on the CAT5 cable. The security issues … well, it depends on how paranoid you want to be. In your case, a very good, basic and free approach would be to turn ON the Windows Firewall anyway, and make sure that File and Printer Sharing was turned off.
Stronger security would, I believe, involve a more sophisticated router that would give you much more control over what types of network traffic is allowed to go where. This gets really ugly really quick, and people make careers out of cofiguring these things. But some level of additional hardware or more advanced hardware would be required.
Of course everyone could have an additional broadband router, and that would be secure and work for simply email and web browsing, but other things could break.
I want to start a web server, so that it can be accessed from all parts of the world. So can i start the web server using this IP ad what are the requiremnts. Please Help me in this regard. Hubs cheapest while Routers expensive. People buy this network things based on their spending capability and minimum needs. I have an internet connection thru satelite, can I use it on 3 computers all in the same time? I have a cnet switch but when I tried to network it thru the switch it only gets directed to the providers site and keep asking me for password for each pc.
I had luck once when I put an extra lan card on the server, the built in had the net connection and the other to the port but when I plugged it to the switch it did not see it but when I plugged it on another pc it can surf the net.
I have a cable modem and a switch with 2 computers on the switch. I want them both to have cable internet. Can i use a switch or do i need to purchase a Router in order for both computers to get internet connectivity? A regular E cable has been used between the modem and switch as well as a crossover. One computer gets internet and the other does not.
It is possible to connect 2 PCs with one hub. It now acts much like a server. I am using this setup. Server being my main PC. Although im not using 2 PCs. Just 1 PC and my Xbox My problem is in order for my xbox to stream media from my pc i need to open certain ports.
Trouble is, everytime I fiddle with the wireless router settings, everything goes haywire and my network goes down. The various wired devices are actually plugged in to both of these routers. What do I need to buy to simplify this set up and allow room for expansion?
I am on the fifth floor and there is a linksys g router on the first floor. I have 1 DSL line already installed. I have a Router ADSL, a hub and also another router which in installed to strengthen signal for remotely located computers. We do have a server in the factory which is not operational yet.
We will soon host a web page in it for external suppliers to have access over our data. My main issue is the subnet, i would like to know how should it be done properly, so as to permit the remote computers to have access to the computers connected directly to the hub. Thanks for you reply. Questions are welcome. We have an 8 port Linksys wired router in one room, connected to cable modem and various computers, voip , and 2 gaming systems. In our office I would like to add a Dlink ethernet hub to be able to connect a mac and windows box to the network.
Did not work. The windows computer could not connect to the internet. What am i saying? Even tho you identified internet security as your single topic I think you should still increase your coverage.
Depends on the network traffic. Its a wonderful description of the device. I think its worth mention the differences and on which layer the devices are applicable.
This will provide the reader with more precise view of the device that a lay person can understand about the devices and its functionality. Thank you so much! There are tons of websites about this and I had no luck at all. Then I stumbled across your site and found the problem to be most simple.
I have a hub and not a router! Simple enough solution — go buy a router. You saved me from pulling out my hair and strangling myself with it. I currently have my machines XBOX, Gaming PC, and Storage PC running through a switch into a router, and the rest of my families machines a further 3 are plugged directly into the router. One of my dads friends tried to tell me that with the switch I should be able to get my full bandwidth on all computers.
My understanding is that you have a certain amount of bandwidth and the hardware will grab what it needs for the application, when that exceeds the bandwidth you have that creates latency. I would like to disprove or appologise, either way cheers for your time. Do you imply that if i use only a hub to connect to the internet i might have less firewall protection.
We just recently got dsl at our house and have 2 computers and a Playstation 3 to use onine. We want to be able to use all of these or at least 2 computers online at the same time and I have been advised to go get a hub or switch instead of a router. Im extremely confused about all of this. Ive read tons of stuff about hubs and switches and routers and how they different.
I did read your article and it was a little bit easier to understand but i am still very confused. We have 3 people in our home fighting over one computer and one dsl box. So what would be the best thing for me to buy and is a switch basically the same thing as a router? I want to be able to do all the same things i do now, without it slowing down and stuff. I need advice terribly, i have asked everyone and no one will give me a good answer.
If someone could please help me I would greatly appreciate it!! Should I buy hub, switch or router? Re: What is the Difference between Hub and Switch? Answer 1 HUB 1. Hub is a Layer 1 Device 2. Hub is not more intelligent device 3. Hub does not reads the frame 4.
Hub provides the always broadcasting in the network 5. In Hub the rate of data transmission is slow 7. Hub does not create any table. Switch is a more intelligent device 3.
Switch reads the frame 4. Switch provides conditional broadcasting in the network 5. In Switch the rate of data transmission is fast 7. Switch is a full duplex device 8. Switch provide packet filtering in the network Switch is a single broadcast domain By default Switch is a separate collision domain Switch creates a table that Table is called switching table. It is connected large network. If you have multiple pcs in your house the best way to connect all this with out any effort is to purchase a wireless router.
I have quite a question for you! I have run a local speed test bredbandskollen. That feels like an enourmous drop in speed. How should I share this internet connection in my house and maintain maximum bandwidth? Obviously the router eats more than half the bandwidth as of now. I have a modem at home with one internet plug but provider says i have possibility to have two dynamic IPs in pararel and for that i have to use kind of switch.
I dont get it. Because to the switch or to the router I could connect 5 or more computers. Which of the computers will get which IP? Thanks for the answer. I have a friend that has 5 computers in a network. My question is how can we connect the 5th with a lan cable to this configuration.
Do we need a Switch, or a router? One computer is a file server for Quickbooks so we need all 5 computers to be able to see each other over the network and be able to access the internet independantly of each other. Also it would be good if we could plug a networked printer in the jumble to. What about if we just used the 2 wire single port modem, if you plug that to a switch will it work the same????? Any help would be great. Thanks Steve. Please advise thanks Brandon.
Steve Connect the 2 wire to a switch. Connect all else to the switch using ethernet cables. All should seamlessly work! I browsed many of the question but not all and it still looks my question is slightly different then many of the other question. My network is very mix; I have machines running wireless, machines connected directly to Fios router and some machines Xbox that are connected via powerline extension. All works just fine as far as I can tell.
Now, my powerline extensions are connected to my media center where my Xbox is located. A TV can also have a network port so it can connect say to Netflix. Those are more devices then computers. In those cases, what should I be installing next to the media center area? A hub or a switch? Sounds like I can go with a hub as those machines typically don. Well, as stated in the article, it depends on what devices are going to be connected to the device. If you are looking for speed, I suggest you get a switch.
If you are looking for price, I suggest you go with a hub. The price depends on how many ports the device has along with what brand it is. Switches can run between fifteen to several hundred dollars. Once again it all depends on the brand and how many ports it has. A simple four-port switch can run you between fifteen and twenty-five dollars. By the way, be sure to check all the ports on the hub or switch you get.
Sometimes they will come with a dead port. In most cases, you can return the device to the manufacturer who will, or should, replace it for free. You will have to pay for shipping, however. Well… they can. You can connect a switch to a hub, a hub to a router, or a switch to a router. This is how many large networks connect all of their devices to the internet. They usually have a single router with several switches attached to it which have switches of their own, and so on.
Usually the computers themselves are connected to a hub that connects to a switch. Of course it all depends on the amount of network-requiring devices. Maybe like 5 switches one for every 10 , or something. Maybe even less.
It all depends on how fast the connection needs to be and how much money the IT department has lol. Will a switch or router solve the problem. But you have not indicated that we also have layer 3,4 and 7 switches which can in some respect replace routers.
They are even smarter than routers. Hub is take a data and sending to all conneted networks but 2 Swich is unicast sending data only one machin to connected switch. I have a very interesting setup that I am working on for a client right now. The client has a network of about 25 users. They are experiencing very very slow internet load times slower than one would expect even if the slow connection is shared over 25 computers.
The DSL modem is connected to a switch provided by the ISP which is then connected to a 24 port switch, which is then connected to a wireless switch. Most computers are connected directly to the 24 port switch and a few connect to the linksys wireless access point. The large switch is full and the wireless hub has about 5 laptops connected plus a few desktops.
The first switch after the modem only connects to the second large 24 port switch. Quick question. Thank You Leo!! I am having problems with all the terminology in my networking class. I appreciate your simplicity with such complex issues. I finally understand!
My networking connection is modem from the ISP is connected to a 24 port switch,and all the 10 system connected to the switch. I have a broadband router for my network. For your article it would be good to note whether adding a switch for additional network devices is sufficient, or whether the intellegence of an additional router is an advantage.
I took a lightning hit damaging my hub, and now I cannot get all workstations up, with a new HUB, and I even tried a switch. I then run each cat 5 cable out of the few working ports. Any ideas why a new hub would not work? I am last year computer science graduate…. For this I need the master PC switched on, always. I have one IP with one connection. I came to this site looking for differences between the equipments, but could not make out and hence this post.
I have a 4 port linksys wireless router. What can I add to this router to expand my ports. I need another 2 for network printing eithernet. I have a 16 port d-link switch that will only work behind my linksys router, but not when hooked directly from the modem…is this normal, or is there something wrong with my switch? Anyway, am I just screwed, or is there something Comcast or me can do for me?
How does one physically differentiate between a router and a switch? If the switch is not as intelligent as a router, then how come a network can be fully switched? Or, would a fully switched network eventually connect to a router?
We have a cisco switch at the end of our network connected to the wireless router connected to the modem. Nothing about the network has changed re: set up or provider, yet the dropping is becoming more of a problem as time wears on. Do you think we have a switch issue? Any suggestions? I have a LAN which is connected to a router. My Internet modem with inbuilt router is now connected to this router. In a domain using the username and paswd any one can log into any system so if the router that is a system then i know how to stop simply changing permissions to login will stop access but if in case of routers, configuration has to be made through commands using some interface.
Is the way to share same speed all the systems? Hello Mr. Can I connect both to a single router and enjoy the sum of both connection speed from that router when only 1 PC connected to that router?
I have a 5 port switch, and a linksys wireless hot spot with only one port which is the ethernet input. The problem is I can ony get one thing to work at a time, I connect my VoIP, and it works great but no enternet, and so on. Can I use a switch in this way or will I need a roughter? Thanks in advance for you time. One thing that is cool is that the cookies are browser specific.

For instance, if you usually use IE, then use Chrome or Firefox. Well Explained and informative, even i found this link helpful.. Thanks for the excellent explanation. If you mean safe from hackers accessing your computer, then, yes. How does a VPN protect me? Can I daisy chain a router?
My hub has no more room and I have an extra Linksys router. The main router is the same make and model. This Leo has just come in perfect for me. I do voluntary work for a charity helping network the building. I wanted to give the Hp printer a static ip address.
I realised that each time the printer was switched on a different ip address was given by the DHCP server. We then deadicated a pc as a server to increase the speed of printing mainly for Coral draw , also to stop people from having to ask for the printer back.
