Ok can someone explain to me all the different internet speeds?

[neomits]

Right now I'm living on campus in a dorm and I've been told that we have a T3 connection and I've also been told we have a T1 connection. The fastest DLs I've seen coming to my computer are about 1.5 megs/sec and thats DAMN fast. Next year I'm moving off campus to an apartment community. They said that there, you get a base connection of 128 but there is a T1 line running into each of the 2 buildings so you can upgrade. Now how much slower will I be running? Where does 128 fall compared to DSL and cable.

I know there is someone out there who can give me a well laid out table of speeds and charts and explanations!?!?!

t3 connections are rated 45 Mbps

t1 are rated at 1.5 Mbps

Dsl can run from 128Kbps - 7 Mbps down and 128Kbps - 1 Mbps upload.

 

Kbps / 8 = K/sec.

 

[neomits]

So when they say a 128 connection that means I'll be getting 128 Kb/sec?

 

[erikiksaz]

Not usually, it'll be 128/8 = 16kb/sec

 

[John]

You will get roughly 15KB/sec downstream

128/8 = 16 Kb/s ?

<< Kbps / 8 = K/sec. >>

K/sec is ambiguous. Try this:

Kbps/8 = KBps
Kilobits per second / 8 = Kilobytes per second

wow t-3 send it to my house lol, i am on dial up again,,,:Q

 

[neomits]

15k UGGG thats a major drop

so pretty much its a small upgrade from 56k


what does ISDN mean?

Right now the entire campus is sharing a T3 and a T1

45 Mbps (45 Million Bits Per Second)
T1 (1.5 Million bits per second)

We will assume that these links are not fully utilized, and your max bandwidth comes down to your computers connection to the network. More than likely, your connected to the campus network is via 10BaseT Ethernet at half duplex

10BaseT - 10Mbps (10 Million Bits per second)

At half duplex, the typical usable bandwidth is about 5 Mbps. So, the likely factors that cap your bandwidth are:

1) The network Interface card in your computer (I have yet to see the average card pull 10Mbps)

2) The various bottlenecks on the Internet, including the host your downloading from.

Point? At 1.5 Mbps your doing well.

As far as the off campus gig, at the base offering, you'll get 128 Kbps (128,000 bits per second), a noticeable downgrade from the campus network.

128K and 384K symmetric speeds are common DSL offerings, while cable usually offers 1.5Mbps Downstream (to you) and 150 to 300 Kbps Upstream (from you)

Upgrading to the T1 depends on how many people are sharing that T1. If you are the sole user of the T1, your speeds will rival the campus network. Your next question should be; how many units/users is this single T1 capable of servicing, and how many are currently using it.

Hope this helps.

thanks for the info breezeman

you will be roughly running 90times slower...

the download speeds ppl tend to notice are in the BYTES per second as indicated by internet explorer's download panel. so that would be 1.5 megabytes per second, roughly 1500 kilobytes per second, or 12000 kilobits per second. which is roughly 90 times faster than 128 kilobits per second. advertised speeds are usually in the BITS per second.

though i am sure you mean 1.5 megabytes per second... if you are running 1.5 megabits per second, you are roughly going to be running 12x slower.

don't forget your capitals, peeps.

KB for bytes
Kb for bits

8 bits in 1 byte

you guys ever hear of OC-768?

try 39.18Gbps

Where do I sign away my soul?

i will pass on that, since my harddrive is slower than that

Your soul isn't worth as much as the Optera Metro equipment costs. :Q

 

[krystalogik]

so where do I sign away your soul?
