10Base-T Ethernet Hub capping my T1

Hello,
I was wondering if I bought a Netgear EN104TP 4 Port 10Base-T Ethernet Hub, if it would cap my T1 connection?

http://www.netgear.com/products/details/EN104TP.asp

I download sometimes at 800k/s or higher, would this hub limit me to 100k/s? I don't want any internet speed lost because I am using a hub that can not handle high speeds. Thanks for any help!

Nate

Math wasn't my strong point either.

10megabyte vs 800 kilobytes. So it takes 1000 kilobytes to make 1 megabyte right?

A hub will not "slow" down or constrict your bandwidth. How many sessions [pcs] and what you download will constrict your bandwidth.

Your biggest issue is that you should get a router not a hub since normally the isp only gives you one ip address. Unless you want to bottleneck your bandwidth by going thru ICS [internet connection sharing]

A T1 operates (Europe has another standard with a little more bandwidth) at 1.54Mbps both ways (upload/download).

A Base10-anything operates at 10Mbps both ways.

"10megabyte vs 800 kilobytes"

That's not quite correct in this context. A megabyte (~1000 bytes, ~8000 bits) is not the same as a megabit (1000 bits). Network bandwidth is measured in bits. Many hardware specifications are measured in bytes (though confusingly, not always).

MBps is for megabytes per second, and Mbps is for megabits per second (or mb/s, m/s).

Also, many products use the large "B" erronously as bits, when a large "B" is really supposed to pertain to Bytes.

Like anonproxy said, all networking communcation should be referred to in bits. So if you see two network cards, one says 100MBps and another says 100Mbps, just assume they are both given as megabits per second. The companies that put 100MBps on there network cards are either purposely being misleading, or are just stupid.

yes indead there is a big difference between bits and bytes. It has become a loose defination as was my spelling. The point is that a 10Mbps hub is not going to be the bottleneck on a 800kbps download speed T1

In the US we can get Fractional T1s starting out at 56K to full 1.54. But usually these questions are from ADSL or cable users.

10Mb anything doesn't always travel at just 10Mb each direction. It depends on if full or half duplex. Full does two way communication at the same time which makes for a total bandwidth of 20Mbps. On the other hand, at half duplex, where one side shuts up while the other talks the bandwidth is only 10Mbps.

Thanks for the refresher in Mb and MB :-)
