I'm doing my first year of university at OU (week 2) and I was getting the file transfer question wrong.
I've been trying to practice this and going on website's that calculate this for you (to check my answers) I found that I was around 20 seconds off.
This is my working out:
50MB being downloaded at 512Kb/s (time it would take to download)
50MB x 2^20 = 52,428,800 bytes x 8 = 419,430,400 bits
512Kb x 1000 = 512,000 bits (per second)
419,430,400 / 512,000 = 819.2 seconds / 60 = 13.66 minutes
http://www.download-time.com/ --- tells me it should take 13.39 minutes
Now is there a conversion between the .66 decimal on 13.66 that I'm not doing or is there something else entirely that I'm getting wrong?
Thanks for any help!
Should you be doing them as well?
