What is the actual thru-put rate for a 384K link?

 

 

 

Example:  If I upload a 1 megabyte file, on a 384K upload link, how long will it take in
seconds?

 

Note that 384K is >kilobits< per second not BYTES per second (I believe).

 

I'm getting lost in "Morning Math".

 

And I don't know the transmission protocol overhead.

 

If the computer/transmission is using a 32 bit byte, (or do ISPs still use 16 bit
bytes???)

then a 1 megabyte file is 32 million bits (32,767,000) , or 1 million bytes (1,024 million
bytes).

 

32,767,000bits  / 384,000 (bit per second) = 85.33 seconds.

 

BUT there is the "overhead" or bits used by the protocol.  (I guessed a 50% overhead to
start with

since I do not know.)

 

So in reality it would take 85X2 or 170 seconds (approx) to upload a 1 megabyte file.

 

Can someone help me here?
