False Part II Hardware| Function| Installation/Maintenance| Hubs| A hub is a device that takes incoming data and broadcasts it out to all the other devices that are connected to its ports. | Installing a hub is very simple. Basically all you have to do is plug and play. Remember not to plug any cable into the uplink port of the hub because that is used to connect hubs together. Because all a hub does is rebroadcast data, not much configuration is needed. Switches| A switch is like an intelligent hub. A switch can create a record of all the hardware on a network and send data more efficiently. It operates higher up the OSI model than a hub. | In most cases the installation of a switch is fairly easy. Plug the switch in and allow it to boot up.

When all the devices are connected, turn them on and in most cases they will be connected to the network. Sometimes special configuration will be needed, but in most simple installations the switch will work right away. Remember to not connect a device other than another connectivity device to the uplink port on the switch. | Routers| A router can connect different types of networks together regardless of certain protocols. Routers operate higher on the OSI model than most switches because they can deal with more complex network traffic. | Because the router is a more advanced device, there are many more options that can be configured on a router. There are many instances where little configuration is needed, but in more advanced installations proper training in routing protocols is needed. On a connection level, routers are very similar to switches when it comes to installation. | Bridges| Bridges operate on the same level of the OSI model as switches, and are basically a simple version of a switch. Each bridge has one input and output, and this is used to filter data going between different network segments. | Bridges are fairly simple to install. Because the function of a bridge is fairly simple, the installation follows suit. They are used to connect different network segments. The input on the bridge would throughput to the output that is connected to the next segment of the network. They require little setup because they build their own lists of devices on the network in order to filter out the data that doesn’t need to go to the next segment. | Part III When it comes to choosing what type of connectivity device to use in your network there are several factors to consider. Network size is one of the most important. Hubs can handle many different kinds of network traffic, but as soon as a network gets to a certain size, it becomes more efficient to use a switch because of the data management properties that switches have. Traffic will move faster with a switch on a larger network, and be more accurate. A router would be brought in if you were to connect two different networks together, say a group of Mac workstations that need to have connectivity with Windows workstations. T, the router is important because it can link together separate networks with different protocols because the router asks like a translator. Switches are a good choice for larger networks because they can manage the traffic and create the best paths for data to flow. This can result in increased network efficiency, but if configured wrong, can also create problems. The hub can be relied upon in all different situations. A small group of nodes can be connected by a hub in a home or small office network. This is a cheap solution to connectivity, but in the event that a network gets large and more complex, it might be worth it to think about getting a switch. Works Cited Dean, T. (2010).
