Can anyone tell me the difference between 1 gigabit and 1 megabyte?

1 gigabyte is 1,000 megabytes.

Is that what you wanted?

A gigabit should be around 125 megabytes according to some quick calculatoring.

(1,000,000,000 / 8) / 1,000,000 = 125

1,000,000,000 bits in a gigabit. 8 bits in a byte. ~1,000,000 bytes in a megabyte.

A bit is a 1 or 0 (on or off). Eight bits make up a byte. Each byte is a character represented by a mixture of eight 1s or 0s.

So the word "jello" would be made up of 40 bits.

EDIT: And here is "jello" in binary: 0110101001100101011011000110110001101111

So, sending "jello" over gigabit ethernet would take 0.00000004 seconds under ideal conditions.

Oh, sorry, poor reading on my part.

There are 8 bits in one byte, so 1 gigabit is equal to 125 megabytes.

EDIT: ...And dpaanlka, I saw that.

Shhhhhh!

Here is a fun table.

Thanks, does that mean that 1.5 gigabits/s is equal to 187.5MB/s?

Yes, it does.

Wow, that was the most technical/educational thing that I have read all weekend.
