help on converting megabytes inro bits per second

Hiya,

Its been a while since I posted here.

i need some help on how to work something out, I would like it if you were
to show me how to do it or point me to a website.

I have this assignment, It is designing a WAN. I have a network design tool
called Delite.
My problem, I have been given the population of users at a given site, with
the total amount of data transferred at that site in megabytes. I need to
convert that into Bits per second for each user.
how do you do this?

Also, we had to find out the horizontal and vertical (longitude/latitude)
co-ordinates of each city, I used Mult-map to do this and it had the X and
V co-ordinates in metres, I just converted them to kilometres which was
required. Does that sound ok to you?

Thanks for your help,

Jayne

First convert from Megabytes to bytes per second, then multiply by 8 = bits
per second.

1 byte = 8 bits

Does that data rate include the encapsulation overhead, or can you
overlook that in the problem?

As was said, 8 bits = 1 byte, so just multiply by 8.

Scratching my head... You were asked for latitude and longitude, so I
how is that rated in kilometers? Latitude and longitude use degrees,
minutes and seconds as units of measure, not meters and kilometers.
So I am not sure I agree that your answer fits the question. Am I
missing something?

First convert Megabyte to Kilobyte, then convert Kilobyte to Byte and
finally convert Byte to bit.
1 Megabyte= 1024 Kilobytes
1 Kilobyte= 1024 Bytes
1 Byte = 8 bits
In other words, 1 Megabyte = 1024*1024*8 = 8388608 bits
or 1 MegaByte = 2^10 * 2^10 = 2^20 Bytes
or 1 MegaByte = 2^10 * 2^10 * 2^3 = 2^23 bits

I think we can overlook that, but encapsulation may be a good thing to write
about in my report.

Thankyou,

Well, we needed the Horiziontal and Verical co-ordinates for these 12 sites
in France, and they need to be in Kilometres, so I made an error when I
said Latitude and Longitude I believe. I went to an Internet site called
Multi-Map to get the X and Y co-ordinates in metres and then divided them
by 1000 to give me the kilometres.

Again, thankyou

Thankyou, that is just the information I am after.
