This actually depends on what you are counting or using the terminology about.
Transfer of information over wireless or through cable and storage on hard disk etc uses the decimal version 100%.
This mean that 1 Mega bit is 1.000.000 bits and 1 Giga bit is 1.000.000.000 bits.
However.
If you count bits as in memory bits in a computer, then other rules apply.
Short example.
1 Kilo bit is with previous method 1.000 bits.
This can be written in Binary number system as 1111101000 bits
As you see, there are empty spaces in the binary number (filled with 0).
We make more efficient use of memory to fill all available spaces with 1, hence why we say that 1 Kilo bit memory is actually 1024 bits.
A gigabyte is bigger than a megabyte
10 megabit 100 megabit 1 gigabit (1000 megabit) these speed ratings are theoretical
32 megabit = 0.032 Gigabit
One Terabyte is equivalent to 1000 Gigabytes One Gigabit (or Gigabyte) is equivalent to 1000 Megabytes One Megabit (or Megabyte) is equivalent to 1000 Kilobytes One Kilobyte is equivalent to 1000 bits
A byte is 8 bits. So 1 gigabit(Gb) = 0.125 gigabyte(GB)
Gigabit Ethernet almost always runs in full-duplex mode
Firstly it's called Gigabit and Megabit network cards. Gigabit is ten times faster. 100mbit vs 1000mbit :)
It is not a complete necessity to have a gigabit Ethernet switch but it will increase processing speed to 1,000 Mbits per second. Earlier forms of the Ethernet switches were in the 10 to 100 megabit range.
In ascending order (least to greatest), it goesBit, byte, kilobit, kilobyte, megabit, megabyte, gigabit, gigabyte, terabit, terabyte, petabyte. I think petabit MAY be right between terabyte and petabyte, but it is underlined when I type in to my computer, so I am not sure.
Kilobits = one thousand bits per second transmitted Megabit = one million bits per second transmitted
A gigabit is 1000 times the size of a megabit, I believe. If this is the same as bytes (I believe the values are 1/8 of bytes), meaning 1000 (1024, really) megabytes = 1 gigabyte, then 1000 (1024, I assume) megabits = 1 gigabit. Either way, giga is always greater than mega, whatever the suffix is.
