Its a wonderful description of the device.I think its worth mention the differences and on which layer the devices are applicable.This will provide the reader with more precise view of the device that a lay person can understand about the devices and its functionality.

Thanks

Thank you so much! I've spent hours trying to reassign an IP address to one computer or the other in my 2 computer "network" because only one can connect to the internet at the time. There are tons of websites about this and I had no luck at all. Then I stumbled across your site and found the problem to be most simple. I have a hub and not a router! Therefore, I'm simply not going to be able for both to be online at the same time. Simple enough solution - go buy a router. I'm glad you had my solution. You saved me from pulling out my hair and strangling myself with it. :)

The main difference is that the Hub is half duplex and the switch is full duplex....

I currently have my machines (XBOX, Gaming PC, and Storage PC) running through a switch into a router, and the rest of my families machines (a further 3) are plugged directly into the router. One of my dads friends tried to tell me that with the switch I should be able to get my full bandwidth on all computers. Is this possible/legal? My understanding is that you have a certain amount of bandwidth and the hardware will grab what it needs for the application, when that exceeds the bandwidth you have that creates latency. I would like to disprove or appologise, either way cheers for your time.

In router how many interfaces we can create?

It means you can only use a switch to make your network work faster, rather than a hub.

Do you imply that if i use only a hub to connect to the internet i might have less firewall protection.

Absolutely. A hub (or a switch) provides no firewall protection.

We just recently got dsl at our house and have 2 computers and a Playstation 3 to use onine. We want to be able to use all of these or at least 2 computers online at the same time and I have been advised to go get a hub or switch instead of a router. Im extremely confused about all of this. Ive read tons of stuff about hubs and switches and routers and how they different. I did read your article and it was a little bit easier to understand but i am still very confused. We have 3 people in our home fighting over one computer and one dsl box. So what would be the best thing for me to buy and is a switch basically the same thing as a router? I want to be able to do all the same things i do now, without it slowing down and stuff. I need advice terribly, i have asked everyone and no one will give me a good answer. If someone could please help me I would greatly appreciate it!! Should I buy hub, switch or router? to simplify it...my connections speed is 1.5mbps (100mbps) normally.

Thank you

Not sure why someone would tell you not to get a router, unless your DSL modem is already acting as one. A router of some sort is the way to share an internet connection. I'll point you at this article: How should I set up my home network?

Re: What is the Difference between Hub and Switch?
Answer
# 1 HUB
1. Hub is a Layer 1 Device
2. Hub is not more intelligent device
3. Hub does not reads the frame
4. Hub provides the always broadcasting in the network
5. we cannot configure Hub
6. In Hub the rate of data transmission is slow
7. hub is a half duplex device
8. the rate of data transmission is divided in hub
9. hub does not provide packet filtering in the network
10. hub is a single broadcast domain
11. hub is a single collision domain
12. Hub does not create any table

SWITCH
1. Generally Switch is a Layer 2/ Layer 3 Device
2. Switch is a more intelligent device
3. Switch reads the frame
4. Switch provides conditional broadcasting in the network
5. we can configure Switch
6. In Switch the rate of data transmission is fast
7. Switch is a full duplex device
8. the rate of data transmission is not divided in Switch
9. Switch provide packet filtering in the network
10. Switch is a single broadcast domain (By default)
11. Switch is a separate collision domain
12. Switch creates a table that Table is called switching
table

1) It is non intelligent devices.
2) Half duplex devices.
3) Send or receive the data at a time.
4) Single collision domain.
5) Single broad cast domain.
6) Layer1 devices.
7) It is connected small network.

SWITCH

1) It is intelligent devices.
2) Full duplex devices.
3) Send and Receive the data at a time.
4) Single broad cast domain.
5) Separate collision domain.
6) Layer2, Layer3 devices.
7) Large no of port compare than Hub. It is connected
large network.
