what is difference betveen hub and switch?

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.

I made the switch last week and it's a lot easier to use. I had no problem with the switch and everything moved seamlessly. The beta is better because it has better access control for private blogs, use labels to tag posts and search quickly, and it has more feed options for posts and comments including RSS and support for Feedburner. Best of all it's linked with Google and automatically logs in to the dashboard if you are logged into your Google account.

without a hub or a switch you would need a crossover cable availible anywhere. if you get a hub or a switch you can use two patch cables. make sure they both belong to the same workgroup and you should be good to go

Toggle means to switch and hold states, such as on or off.  \n\nMechanically, you can think of a toggle switch that has two positions.\n\nElectronically, there are many examples.  S chmit t triggers being one particular example, in which a momentary input is maintained at the output.   A good analogy would be a ball point pen.  Click it once to use it (turn it "on"), click it again to stow it (turn it "off).

Hubs and switches are significantly different.  A hub is nothing more that a device that allows multiple devices to connect to a single network connection.  It also acts as a repeater.  In other words, it helps keep the packet signal strength strong enough to traverse one or more network segments.  When a packet enters a hub, the hub sends the packet out all ports.  So all devices connected to the hub see all the packets passing through the hub, whether addressed to them or not.  With large hubs with a large amount of traffic, this can cause performance problems.  A hub operates at the physical layer, or level 1 of the OSI model.\n\nA switch traditionally operates at layer 2 of the OSI model.  The primary difference between a switch and a hub is the way packets are handled.  A switch knows the MAC (hardware) address of each device connected to each port.  When a packet enters the switch, the switch sends the packet out the port where the target device is located.  Devices connected to other switch ports don't see the packet.  The exception to this is the layer 3 switch.  Layer 3 switch functionality adds routing capability to the switching function.\n\nA switch acts like a hub when a broadcast packet is received.  A broadcast packet is addressed to all devices on a subnet.  So all ports receive the packet.

First, all adpaters must support 100Mbps. If they don't you need new ones.\n\nIn case all 4 and the hub/switch also supports 100Mbps, do the following:\n1. Double click your network connection.\n2. Click properties.\n3. Click configure to set your adapters properties.\n4. Click Advanced\n5. Change the link speed to: 100 Mbps Half Duplex.

Imagine this scenario...You have 3 computers and u want to connect them all and make a small network...how ur gonna do that...here comes hub into picture...Hub allows you to connect multiple computers to share a single network...and Switch is a bigger brother of Hub normally with 10 to 24 ports, and router is altogether different from hub or switch ...routers r used for Wide Area Connectivity....that is between different networks....Hope this solver ur prob buddy.

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.

A bridge converts one type of cable into another (ie. a phone line into a ethernet cable). Whereas a switch is the same cable.

jumphers are the hardware switches, it's used to togle between the choices.

A hub allows any number of devices to send/receive data packets at the same time.  It is a "dumb" networking device, providing no traffic management features.  As a result, its efficiency is reduced for each connected device that is attempting to communicate.  It's an "everyone sends, everyone listens" setup.  An anaolgy would be a old "party line"-style telephone system where you share a single phone line with several of your neighbors.\n\nA switch manages network traffic by directing traffic between networked devices communicating with each other.  This results in greater amounts of total bandwidth being available to all connected devices.  A corresponding analogy is private phone lines where you establish a direct connection to the person you're communicating with.\n\nSome switches are better than others at managing traffic and offer more features than just basic switching.  These are usually most useful where there are a dozen or more connected devices.

Always make it that if you are connecting two devices you have to use cross cable and if u are connecting a computer or device through switch or hub you will have to use straight cable.pleasec chech the link below it will give u the complete picture

depends on what program you use - you should be able to switch back and forth

A hub, or repeater, is a fairly unsophisticated broadcast device. Any packet entering any port is broadcast out on every port and thus hubs do not manage any of the traffic that comes through their ports. Since every packet is constantly being sent out through every port, this results in packet collisions, which greatly impedes the smooth flow of traffic.\n\nA switch isolates ports, meaning that every received packet is sent out only to the port on which the target may be found (assuming the proper port can be found; if it is not, then the switch will broadcast the packet to all ports). Since the switch intelligently sends packets only where they need to go the performance of the network can be greatly increased.\n\nMore expensive switches can also do several other operations, such as isolating ports from each other by placing them in different VLANs, or allowing snooping by copying all packets on some set of ports to a special "sniffer" port.\n\nThis leaves the question of when a switch is most appropriate, versus a hub. If most of the network traffic involves only a few ports, then there will be little performance gain achieved by upgrading from a hub to a switch. But if the traffic involves more than a few ports, using a switch can yield a significant improvement in performance. Also, modern Fast Ethernet switches designed for small office / home office (SOHO) use are priced comparably to hubs, making use of a hub somewhat pointless if new equipment must be purchased anyway.

The ce-500 line of switches that I could find (such as the  Catalyst Express 500 24-Port 10 100 PoE Switch) support SFP uplink ports.  The SFP ports can take multimode or singlemode fiber ports.

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.

switcher-  the term is actually SWITCHES.  a switch is a level 2 networking device that directs data to nodes (PC's) via MAC Address.  think of a light switch... when in one position the light switch will direct electricity to a light bulb... in another the light switch will direct the electricity back into the house.  Except in this sense, the switch will direct things automatically and can direct thousdands of things per second.\n\nLow-End=  a low cost solution for beginners or small networks\n\nHigh-end= a higher priced but more capable device.\n\nOver the counter= available to everyone with no special requirements to purchase.\n\nThe mystery sentence is saying that in the year 1997, the Companies stock was selling for 83 dollars on the stock market.\n\nscalability=  a term used to define how flexible a system is.  a "scalable" system can be expanded easily in the future if the network needs to grow.
