I have a question about the 10/100 nic cards and networks..

If my nic is a 10/100 mbps thats bits per second correct?

So is that 10 million bits per second? so thats 1 megabyte per second? and 60 megabytes per minute correct?

Not quite!

Mbps is megabits per second. So 10 Mbps is (roughly) equal to 10 million bits per second (depending on the source you use for the definition).

However this is not equal to 1 megabyte per second. Normally, a byte is defined as 8 bits. I leave you to do the math.

Ok here is the maths bit

10 mbps is 10 million bits per second using decimal maths it is EXACTLY 10,000,000 bits in a second or 600,000,000 per minute.

1 megabyte persecond is a megabyte as defined in biniary maths which goes as 2 x 2 x 2 etc and 1 megabyte is actually 1,048,576 bytes which is 8,388,608 bits per second.

So technically 10 mbps is 1.19209 megabytes per second.

Now that all relates just to the total number of bits/bytes that can be send. Any actual transmission includes an amount of administrative overhead with parity or check bits and connection handshaking etc so that actual useful data transfer rate is usually about 5% to 10% less than the maximum capable before you start worrying about slowdown in transit due to other devices.

Hope that helps you out.
