Does hubs split speed? find me guide on networking parts.

[LotharJade]

Two questions.
First, my friend had a hub installed between the connection coming in, his computer, and his tivo. He heard that it splits your speed down with what he said was a hub. He checked online and tested from his computer and his speed was a fraction of what it should be. He replaced and was much better. Does a hub really split the speed, and how does it do this (rough estimate on the calculation)? :shocked:

Secondly, is there a good guide/expanation site that explains the differences between Hubs, Routers, Switches, Bridges, all wireless type stations as well, and Access Points (and other related). First I want to find the best application, and SECOND I am curious what all these things do. Basically I am like my freind in that I have a few things to plug in that occasionally use the internet, and one that should have priority, and max speed. :clock:

If it is a 10Mb hub it splits 10Mb among all connections. I'm pretty sure that means 5 up 5 down so a file transfer from one computer to another would potentially slow your internet connection. Switches have 100Mb per port and are full duplex. Google the networking devices I'm sure it won't take long to get it figured out.

Do not concern your self with Hubs it is part of History, it even hard to find one.

The following is a set links that include very basic explanations and could take it from there.

Link to: AnandTech - FAQ. Basic Options for Internet Connection Sharing

Link to: AnandTech - FAQ. Hubs, routers, switches, DSL, LANs, WANs...?

Link to: AnandTech - FAQ. What do I need for wireless Networking?

The pages above were written by me a while ago. Ignore the prices and the Hardware recommendations, stick to the principles.

Link to: Diagram of Broadband Connection with Cable/DSL Router.

In general: Cable/DSL Routers - NAT & Ports.

Link to: Wireless Cable/DSL Router or Access Point ? What should I get?

hubs are layer 1 devices that just repeat what information comes in on every port.

Kinda, funny. My fiend set up a system a year ago and when he did, he ended up with a hub. Plus I see the things in stores around here all over the place. Hmmm, must be an Alaska thing. (for example, I hear a lot of servers down south are linux, while here they are still stuck in windows. Kinda funny.)

A hub does NOT "split the speed." Every connection that talks (and listens) does so at the full port speed.

A hub is considered "shared bandwidth;" meaning that if one host is talking, all of the other hosts have to wait until the hub is clear before transmitting.

There are mechanisms in-place to handle the event that two or more host try to talk at the same time.

FWIW

I used to have use an Asante 10T HUB. People used to upload viruses to me and I was bombarded with msn messags. I got a router to cut that out.

WRONG!, hubs create a logical buss topology which means you will have 10 up or 10 down, but in half duplex mode.

For those that can't follow that, think of a CB radio, you can talk OR you can listen at any point in time.

This actually has nothing to do with the difference between a hub or a switch. The reason you stopped getting Messenger service messages when you changed to a router is because the router is now acting as a hardware firewall. If you ran a software firewall (such as ZoneAlarm) and made sure you were fully patched, there wouldn't be any difference between the hub and router as far as user experience goes

 

[LotharJade]

So if I add a router (as it seems I will), with a firewall, will I need Zonealarm? Or is it just extra protection?

I still don't get what an Wireless Ethernet BRIDGE is. How is that different from an Wireless Access Point or Wireless Adapter?

A bridge is a device that joins two networks at layer2. A switch is a multi-port bridge.

A wireless access point is a bridge, with the wireless adapter being an end-node (a node that does not connect to any other network - think of a leaf on a tree)

That was my point. The difference is the firewall.

Not entirely correct: A bridge joins two segments of the SAME network togeather at layer 2 (MAC addresses). It can be used to join dissimiliar topologies or prototcols (wireless and ethernet in this case ) or to simply divide the colision domain into smaller ones.

A hub does split the rate of data coming in, for example if ur speed is coming in at about 10mb/s and you are connected to 2 devices that requires data transfers then each device will get aobut 5mb/s of transfer rate. But, wut JackMDS said was absolutely right. Hubs are a thing if the past, it is replaced by switches. With a switch, you will not lose any speed from multiple devices.

Also wut spidey07 was saying is correct, a switch is like a multi-port bridge. but bridges are also very oldschool and it should not be a subject of this discussion...

 

[LotharJade]

Why this came up is I went throught the LINKSYS educational webpage all about networking. Most was fairly simple to do, but it actually suggested in some spots using a bridge, but didn't go into why or what it did. Still seems vauge, but if I can ignore like hubs, that is good.

Actually I believe bridges should be a part of this discussion. The difference between a hub and bridge are very crucial.

A switch acts exactly like a multi-port bridge - that's what it is. Understanding the concepts of bridging is very important to those that want to know more about networking Because believe it or not there are instances where you bridge - wireless access points are a prime example.

The only thing that you got right here is that hubs are a thing of the past.

ALL communication through a hub is 10Mpbs. If two devices happen to be sharing this 10Mpbs bandwidth then the effective bandwidth for each device will be lower, yet the aggregate total bandwidth for the network is 10Mbps

 

[LotharJade]

I wish the different web pages around giving info would update and mention Hubs are old school. Wish they would do some maintenance on their page to update that. Everyone seems in agreement on that issue.

 

[nweaver]

Hubs still have their places, they may be old school, but sometimes you want/need old school (like when you are sniffing traffic from an unmanged switch)
