Diffrence between HUB and Switch?

Question

Few people say hub and switch are same
then i said why company need to launched both.

Answer 1

Hi aryan,

Thats not right. Hub & switch are not same. Both hub & switch work are like same but they are different from his working style. See hub is working in Single domain environment and Switch is working in Multiple domain environment that mins at a time only 1 port can send or receive data on hub and others are waiting for free time. In switch every port have its unique domain so that every port in switch can send & receive data in realtime or same time. thats the main diffrence in hub & switch. you have many more diffrence in technical side but that is very wast subject in networking field.

regds,

Shared versus dedicated channels. In an Ethernet network, every client, server and network device is wired to a hub or switch. A hub shares the total bandwidth among all users, while a switch provides a dedicated line at full bandwidth between every two devices transmitting to each other. In the 1990s, switches were much more costly than hubs, and devices were carefully evaluated based on the traffic requirement. By the turn of the century, switches became much less expensive, and the popularity of hubs began to wane.

In a small home or office, a hub is generally sufficient. However, if many users are always sending large files to each other, the switch eliminates congestion.

For Example:

a. 10/100 Ethernet Hub:

A 10/100 mbps is a good choice these days for basic home networks. This kind of hub will allow you to hook up 10Mbps and 100Mbps devices and network cards on the same network. Furthermore, even if the devices communicate at different speeds, the hub will allow them to talk. Now that the prices have come down to under $50.00, the versatility and speed of these hubs can not be beat.

10/100 Ethernet Hubs are only half duplex - each client can only send OR receive data at a particular time. To take full advantage of your 10/100 Ethernet cards, look into an Ethernet Switch. A switch can operate at full duplex allowing your computers to send and receive at the same time.

b.10/100 Ethernet Switch: Basic

A 10/100 Ethernet switch can be considered a faster version of a 10/100 Ethernet hub. Recently switches have come down so far is price that they are readily accessible to consumers.

Ethernet switches allow your Ethernet cards to operate in Full Duplex mode instead of Half Duplex. Full Duplex means that you can be sending and receiving data at the same time. Switches also route traffic directly between ports instead of broadcasting traffic across all ports. This basically means that each port on a switch gets dedicated bandwidth instead of shared bandwidth. When transferring large files between multiple computers, this can make a big difference in how well your lan operates.

Consumer level switches now run only about 20% more than hubs making them a great deal for the speed. Switches are also being incorporated into many of the popular DSL / Cable modem routers being manufactured.

A hub is a network device that accepts a packet on one port and sends it to all other ports (flood) on the switch.

A bridge (important for knowing what a switch is) is a device that learns what MAC addresses are on each port. When a packet come in on a port, it looks to see if it knows that MAC address the packet is destined to. If it does, it sends the packet out on that port. If it does not it floods it to all ports. A bridge is typically 2 ports and sits "between" two hubs.

A switch is like a cross between a hub and a bridge, a multiport bridge, if you will.

On a hub, if it is a 100 meg hub, only a total of 100 megs across all ports will be available. On a switch, because the switch only sends the data out the port where the end device is (like a telephone switch, hence the name) you can (in theory) have 100 megs simultaneously transferring between any 2 given ports. On a 24 port switch, you could be sending 1200 meg across it.

Hubs and bridges, as discreet devices, are largely obsolete. A switch, particularly a managed switch, is the way to go. Accept nothing less.

Hub is just a connecting device. But, Switch is different from Hub. In switch there is a table is maintained when ever you switch on that. That table maintains about the ip address and MAC address (Physical address) of the systems which are connected in the network. If you send a packet of data from one system to another system in the network the switch will directly send the data to the particular system. But by using Hub, it will broadcast the request to all the systems in the network.
So, The transferring speed is higher than Hub.

Diffrence between HUB and Switch?

Answer 6

Dear, hub is a cheap device used in LAN , but Switch is an Intelligent HUB and can b used in place of hub,but remember switch is very expensive and ranges from series 1900 to series 5500.
Den y don we use switch ?
...simply because its very expensive n require proff. to configure it.It Remove Data Colliosion which a hub can't.
Isaid its a Intell. hub so can limit a colloision to a particular port.

Answer 7

They r certainlydiffrent.

Hub-> is a multicasting device. Data packets arrive n they r passed to all the computers associated with the hub. The right computer with the IP & Mac address will receive the data n others will ignore them. Here u can hack the data with dupe IP since data is sent to all the computers on the network. Security is less. This is the dis advantage. It is cheaper

Switch-> is a unicasting device. Data will be sent only to the computer that has the right IP & Mac address. Has more security. Costlier than hub.

Cheers!

Hub is used to create partition of a internet connection

Answer 9

suitable now, those 2 words are starting to be extra and extra interchangeable, and a few instances even have been given at a loss for words with routers in case of a house router that has a equipped-in "hub" with a pair of Ethernet LAN ports. frequently speaking, hubs could nicely be seen networking contraptions that are working under Layer 3, ie, they don't look to be doing any routing. the undemanding use of hubs is offering get entry to and interconnection for hosts (say, computers). A maximum widespread use, as i discussed above, is to connect diverse homestead computers to an analogous router so as that all of them can hook up with internet. one in each and every of those "hub" could be a hub, or a change. via strict definition regardless of the undeniable fact that, hub is a layer a million (actual layer) gadget that does straightforward interconnection. A hub does not separate "collision domain names". it quite is in simple terms an interconnection container. So all hosts related to a hub could "compete" for transmission. This, regardless of the undeniable fact that, is invisible to purchasers, extraordinarily in case of quickly hubs. In case of a change, it separates "collision domain names" and all ports of it belong to comparable "broadcast area": site visitors won on one port would be forwarded out of all different ports. engaged on Layer 2 (records-link Layer), there's no collision element interior the container and each port gets site visitors from and sends site visitors to each collision area.

Answer 10

should find what you need here, and make sure you get something with DHCP because as mentioned above, you dont want to be doling out IP addresses manually to each machine you use..
