how do you figure questions like these out ?

|
| A user with a 128Kbps ISDN modem will take about how many seconds to download a 100K file?
I get confused sometimes with KBps and Kbps and as this question states, "100K"...
Can someone please enlighten me in as much detail as possible? THanks much! | |

| Time of Download = (Size of file/Available bandwidth).
TD = 100000 Bytes/128000 bytes per sec
Time of Download = .78125 sec.
Be careful not to confuse bytes and bits. Bytes are generally 8 bits. | |

| Thanks for the explanation. The answer is supposedly 8 seconds. So how does your .78125 seconds equate to the supposed answer ? | |

| OK let's say that it is 128000 bits per second...
100000 kiloBYTES = 800000 kiloBITS
800000 kiloBITS / 128000 kiloBITS = 6.25 sec | |

| as far as I can tell people tend to put in say 100KB for kilobytes, or 100Kb for kilobytes, or they end up putting in 100K for kilobytes or 100k for kilobits... I'm not quite sure, but thats how people go about it don't they? I could be wrong, but this is how I've seen it around. | |

| How about this?
How long would it take to download a 1,000 byte file with a 56k connection?
a) 1
b) 1.25
c) 8
d) 8.25
Is the following correct?
1000 bytes = 8000 bits...
8000 bits / 56000 bits/sec = 0.14 seconds?
the best answer is 1 second?
...just need to make sure, cause I'm taking the exam in 2 days. | |

| can someone please verify the above post before I take the exam tomorrow?! Thanks! |
