It would have taken me forever to discover this, if ever. Read on as we show you how to take an old and underpowered Wi-Fi router and turn it into a respectable network switch (saving your $20 in the process). Put in an ethernet extender and it now works like a champ. A networking switch is like smart network hub. It looks just like a switch, but works differently on the inside. This conversation is currently closed to new comments. A switch on the other hand is not a repeater but actually a bridge, which acts upon the content of the Ethernet frame it receives and forwards the frame to the appropriate port on the switch. A hub generally has 4 to 12 ports. Are you exceding the limit?Are the devices at the end 10/100? I think its also the crossover cables, if your switch doesn't have auto-mdx on all the ports, but also see if you have any downstream hubs. Multiple devices can be connected to the LAN … When I upgraded to a switch to cut down on network noise, the switch would not connect. ANS: T PTS: 1 17. Because of these features, a switch is often considered more "intelligent" than a network hub. In general, no, there's no reason to use a hub over a switch, but they do still have a purpose in some special cases. HOLY COW batman. Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. In the picture above, the switch ties a file server, a high-powered PC, a print server, and a hub together for maximum bandwidth. This is extremely helpful! A Hub is a networking device that allows one to connect multiple PCs to a single network. With this table of comparison, you will know why people prefer the switch. It may also be used to route information patterns in streaming electronic data sent over networks. Explanation: Some of the features and functions of a switch include: A switch is essentially a fast, multi-port bridge, which can contain dozens of ports. Some contain a LAN port that can be used to connect a switch or hub to the router and create a local area network, as the router itself may not contain its own PC ports. In a nutshell, if you want to get the most out of your new computers, this is an excellent time to kick that hub … John, the IT Infrastructure Support In-charge in our company, was connecting computers to a LAN. D. A switch decreases the number of broadcast domains. Hi, I’ve tried the same technique with a HH4 and can’t get it to work. You then go to the hub and look for the light that is going on and off. That makes the hub inefficient - in a hub, only one computer can transmit at a time.Most of the time, a switch will send information only to the destination, while a hub will send to all of its ports. i.e. Understanding these distinctions among them can be helpful to find the most appropriate device for your network. Something a lot of people don’t realize is a hub can actually be slightly faster than a switch on some lightly loaded networks. Two-thirds of the cables go into the ceiling. The number of ports that can connect to the device is significantly more abundant in switch while it is less in a hub. ANS: T PTS: 1 16. But I do have one annoying prob. Salman Z. I guess you could say the switch, even a toy one, operates more at layer 2 in the OSI model where the hub … Hubs and switches have two types of ports: medium dependent interface (MDI)and medium dependent interface crossed (MDI-X). A way to map out the network, put the hub back in and get a partner to reach behind a pc, one at a time, and just keep plugging it in, unplugging it until you tell them to stop. Are the devices attached to those cables capable of the speeds offered on the switch ports? I have 14 comp on this network and on the HUB they all work fine. The network is now working, and I have been able to identify some of the cables and have labeled them. The Hub in a network is a device that has multiple ports in it. A switch will build mac address tables and forward most traffic intelligently. These are used to extend the maximum distance between nodes. Another way to prevent getting this page in the future is to use Privacy Pass. The switch can support different common network types like 802.11, Ethernet, Fibre and more. He was setting up a bundle of computers in our conference room and he was networking two computers in the board room. It’s also not secure because it can send data that is not intended for all end-users. John said he will use a switch for the conference room computers and a hub for the two computers in the board room. © 2021 ZDNET, A RED VENTURES COMPANY. Rather than use a crossover cable (whichis discussed in the next section, "Cables Connecting Hubs andSwitches"), you can use the more simple straight-through cable (alsodiscussed in … where a Hub does not.Remember that a Switch only forwards information on by the MAC address locally, and IP address remotely. Types of Hub . A hub may be based on Firewire, Ethernet, or a USB connection.On the other hand, a switch forms the control unit responsible for keeping the flow of electricity. A virtual LAN can be created using a Switch and it can also work as a multi-port bridge Usually comes with 24 to 48 ports Transmits Frames (layer 2 … If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. What two results would occur if the hub were to be replaced with a switch that is configured with one Ethernet VLAN? I recently had an issue where i replaced a companies backbone 24 port hub with a 24 port switch 10/100, and the downstream hub could no longer connect. Thank you so much! Thank you both. ANS: T PTS: 1 It is newer in comparison with the hub, and it more common in the modern offices. My initial understanding is that I can replace a single pole switch with something like the GE Z-Wave Wireless Lighting Control On/Off Switch, if I want it to be able to dim the lights I need one that supporting dimming. Hub vs. switch. Just unplug your devices from the hub, plug them into the switch, and you’re pretty much done. I think both of you are right. Hubs are an OSI "layer one" device. LAN (Local Area Network) is a term used for a group of computers connected to a server in a distinct geographic location, like office etc.To distribute a LAN within a group of end-user devices, we need devices like Hub, Switch and Routers. This maximizes security and efficiency of the network. Hub and Switch. As for the effort to install a switch, it’s minimal. would it really be dependent on if there is a downstream hub? What Is Hub? As there is no documentation available you most likely have some Crossover cables somewhere in that group of cables which are now causing a problem with the new Hub.Sorry but in this case if you can not pickup a similar Switch to the original and even that's no guarantee you are going to have to do some fault finding to see what is happening here. I would also document it as you go along so that the next time that a problem arises some poor fool doesn't need to spend days fault finding.Col. You can then Telnet to the hub and determine which of those devices are connected to which port. Switch 100 Mbps 8 ports can manage until 800Mbps of band-width.
