on the first, yes, maybe. Normally data streams have error correcting codes built in that actully take up "useful" information space.
yes on the second.
Hi,
Can someone check this for me please..
18 MB of data are to be transmitted over a 4 megabits per second connection. How long should the complete transaction take, to the nearest 0.1s.
Size of file / data rate so,
18MB x 10^6 x 8 bits = 144,000,00
4 megabits per second = 4 x 10^6 = 4,000,000 bits per second
so the download time will be
144,000,000 / 4,000,000 = 36 seconds
my answer is 36 seconds is that right
next ,....
a 50 MB file compressed using a ratio of 10 what is the compressed file size
50MB / 10 = 5 MB
Is this correct ???
Thank you :-0)
