can u explain in detail what are hubs and switches?

switch Line 1 and 3. this is the industrial stander. you can also switch any of the two line but you should only do L1 and L3

first u have to build a LAN with 20 systems using a switch/hub then conect both the rooms network with the centralized server.

Hub is a half duplex device.. that means at a unit of time it can either send or receive the data. it works on physical layer and can be called a non-intelligent device.\n\nSwitch is a full duplex device, that means it can send and receive data at same unit of time. A switch has multiple collision domains and one broadcast domain. In addition switch saves routing table of each network connected to it's port in it's memory. (programable switches)

hey dude, why u can't select best answer.\npngarrett is true,\nbut there is need of explaination.\nlet me explain.\n\nBoth ethernet hub and ethernet switch have allmost same function, they connects many computers but the main difference is that, switches stores ur MAC address but hubs doesn't.\nThe benefit of storing the MAC address is that, if u sends a data to a computer and there is many computers between them, but the data only goes to that computer, because the switch have a storation, that this ip address is assign on this MAC address (computer).So traffic makes faster. HUB has not amy facility of MAC address assigning. If u send a data to a particuler system, but it goes to all system and traffic becomes heavy.

Everythiny you want to control with a computer needs an interface -you can build all the progtams you want, if they aren't actually controlling a switch/switch gear/ motors/sensors etc etc then the computer (program) is just a useles box of instructions \n\n- Interfaces COST money unless you are MacGyver ;)

These ports are usually to plug in webcams and low powered USB devices. Most of the USB hard drives or CD drives wont work. Mice n Keyboards depending on their power requirement can work.

Today's star topologies are connected via an active switch, which eliminates collisions...thus higher throughput.\n\nIf you use a passive hub instead, yes, you will have collisions as more and more devices are added to the lan...along with exponential backoffs and slower throughput.

I'll try to give you a simpler answer than the other ones here :) \n\nI assume you are talking about Ethernet networking hubs and switches.  These are devices that route traffic through a network.  \n\nThe main difference is that a hub sends out traffic to everyone on the network, whereas a switch decides who to send it to, based on who it is addressed to. \n\nHere's a simple analogy: let's say that you work in an office building with many cubicles.  Someone comes in with a message for you.  If it is a "hub", the person will scream out the contents of the message to everyone in the office, and people who don't need it will ignore it (presumably).  If it is a "switch", on the other hand, the person will yell out that there is a message for you.  You call him over, and he whispers the message to you.\n\nHubs are generally a little older, and less secure because they send out the signal to everyone.  However some hotels and other public locations still use them, so it's important to use security with a hub.\n\nThese days, however, switches are generally used more often.\n\nHope that helps.

A bridge basically connects two (and only two) networks.\nhttp://www.erg.abdn.ac.uk/users/gorry/course/images/bridge-1.gif\n\nA switch can connect two or more networks.  Unlike a hub which broadcasts a packet to all attached networks, a switch filters traffic to the appropriate destination.\nhttp://www.erg.abdn.ac.uk/users/gorry/course/images/switch-uni.gif\n\nThey both operate at the data link layer, working through MAC addresses to determine whether or not to forward traffic.  They should not be confused with routers which are network layer devices, forwarding packets using the IP protocol.

A proper switch is nothing more then a switching hub, or intelligent hub.  It acts as a logical bridge, but allows a physical and logical start topology.\n\nAs previously indicated a switching hub, can learn where devices are located and send packets accordingly.\n\nYes, you can connect switches and hubs together, although it would benefit you to use switching hubs, preferably from the same vendor.  Some intelligent hubs can communicate and manage resources better within a segment.\n\nFor your project, you may need a switching hub on each floor but not necessarily.  If the distance is not too great for the specific ethernet you select, a "collapsed" network (single star) configuration is much more cost effective.  With the collapsed design you will have to have more and longer "home runs" or cable runs to the ports from the switch, but each port will get full bandwidth.\n\nIf you place a switch on each floor the maximum speed you can achieve is whatever the shared bandwidth is available between the switches, between each floor.  So if you connect two floors with a switch on each floor, and the servers are on one floor and workstations on the other, using a 1Gbps connection between switches - your workstations all share the 1Gbps connection to the server, no matter they have 100Mbps to the switch on their floor - the workstation switch cannot talk faster then 10 X 100Mbps or 1Gbps to the other switch where the servers are.\n\nMost large switches that can manage hundreds of ports have 10, 20 or even 100Gbps communications on the backplane (within the switch itself), providing full 100Mbps communication from each workstation to each server.

You don't need a HUB, that's what the Switch is for.  It's a smarter version of a HUB.  Hook all of your equipment up and then run the Network Set Up wizard in windows.  I would run it on your server first and then the other machines.  Make sure you write down all of your information and input it EXACTLY the same on all machines.  It's called the Network Set Up wizard in XP, I don't know what it is called in ME, but it is there.  Just open up My Network Places to find it.

Short answer:\n\nA router is an intelligent device that allows a central connection to an internet connection.  Basically connects a LAN to the internet.  It also provides many internet like services from that single connection to the PC's connected to it.\n\nA hub is a dumb networking device that only passes all traffic from one computer to all computers connected.  It does not route the traffic in any way.  It's for local area networks only.\n\nThere is also a switch which does a small amount of traffic control in a local area network.  This helps make connections in the LAN faster with 3 or more computers.

A hub is a totally dumb device. If it gets a data signal, it just forwards it to everybody and hopes someone will pick it up. A hub works like a telephone party line. Only one computer can talk at a time.\n\nA switch is just barely smarter. If it gets a data packet, it will try and find the device it goes to, and then send it to that device only, but the device MUST reside on the same subnet. A switch wont send data packets to computers on different subnets. A switch works more like our modern phone system. Computers can talk with each other on private connections so that multiple conversations can be carried on at the same time.\n\nSwitches that support full duplex communications offer the ability to double the speed of each link, i.e. from 100Mb to 200Mb.
