    How Fast Is 1mbps? 2mbps? 3mbps? 4mbps?

    Can someone please try to explain this..

    how long would it take to download a 10mb file on a 1mbps connection? , on a 2mbps connection? , on a 3mbps connection?? etc....

    Im about to get a unmetered 4mbps bandwidth but i need to know how fast or how much users it can handle (streaming music)..

    thanks

    There are 1000 bits in a kilobit and 1000 kilobits in a megabit.

    Therefore, there are 1 million bits in a megabit.

    The conversion from bytes to bits works like this, and beware, this is long handed...

    1 byte (B) = 8 bits (b)

    Since we are dealing in 1 million bytes or bits ( mega ) we will apply the same conversion.

    10 megabytes = 80 megabits

    A 1 megabit per second connection can transfer 60 megabits in a minute and 80 megabits in 1 minute and 20 seconds.

    Since 10 Megabytes is 80 megabits, we can transfer 10 megabytes over a 1 megabit connection in 1 minute and 20 seconds.


    This of course does not factor in anything but the pure math. This leaves out network overhead, distance, the speed of
    the opposite connection, etc


    Now, save yourself some time and use a calculator :-)

    To equate this to your 4 megabit connection, 4 megabits is 4000 kilobits so you can handle approx. ( 31.25 ) 128 kilobit streams.
    Again, this doesn't factor in anything but the speed rating.

    so MBPS means

    Mega Bytes or bits? Per Second

    Per my last post:

    1 byte (B) = 8 bits (b)

    Capital B = byte so you would write a megabyte as "MB" and a megabit as "mb" or "Mb". Lower case "b" means bit.

    Data rates are almost always advertised in bits, not bytes.

    How much are you going to pay for that?

    You can transfer about 330GB/month per mbit.

    so if you transfer at full capacity, for a full month, you will use about 1320 GB

    Its Unmetered 4mbps and i think its just below $80

    One really needs at least 10mbps in my opinion.

    really.. I dont really know how fast is 4mbps or 10mbps until i try it for my self

    I have a powervps right now. their cheapest plan is what I have and its pretty fast. So if 4mpbs is as fast as Powervps' cheapest plan then IM FINE

    For streaming most people use 24kbps (using aac+) or 48kbps. So having 4mbit connection can handle:

    24kbps = 170 listeners
    48kbps = 85 listeners

    PowerVPS offers 100mbit burst.

    4mbit will be significantly slower, not only because you won't achieve more than ~ 400-500kbyte/s (at best), but because it will decrease greatly as more users are downloading from your server. 100mbit leaves a lot of room and usually works great.

    4mbits streaming music isn't very much unless you have less than 200 listeners at any time.

    I agree with Layer0, for streaming, 100mbits burstable is a better option. It allows you headroom just in case you have additional listeners.

    Another way to look at this situation:

    4mbps "unmetered" will pump about 1500MB per month outgoing at full strength.

    If you get a "METERED" plan on a 100mbps connect that gives you 1500MB/2000MB per month (which is common) you'll get better headroom during rush hours and still push about the same MB per month.

    Just be careful not to go over your allotted amount, you could pay big-time in overage charges. Make sure what their IN/OUT calculation is. Alot of Bandwith allocations include INCOMING and OUTGOING traffic in their 2000MB calculation.

    uh... for a dedicated, sure. This is in the VPS forum. Most in the $80 price range will include 400-800MB.

    Most people that are streaming are already setting in their server config a max number of listeners/watchers and therefore since they know exactly how many Mbit/s (or Kbit/s) they will require the 4Mbit un-metered will turn out to be a better value. The situation where this doesn't work out is for one time events, but for the typical streamer it allows the # of listeners to be a defined value without the variable of whether they will pay extra that month.

    Oh darn, sorry guys, I'm browsing the VPS forum and didn't even realize it. Thought I was in the dedicated forum. My apologies.

    You're right, VPS Matt, you don't get that kind of bandwith typically with VPS plans.

    to be but really, speaking for your downloads and download speed you need to use streaming you need upload speed. but with 1 mbps line will be well

    unless you plan to make your own streaming server for what you need for this high-rise.

    1 mbps = 1024 kbps
    1 kbps = 1024 bytes
    1 byte = 8 bits

    one music in MP3 = 128 kbs
