In the computing environment the numerical value represented by the pre-fixes kilo-, mega-, giga-, and so on can vary depending on whether they are describing bytes of main memory or bits of data transmission speed. research the actual value (the number of bytes) in a megabyte (mb) and then compare that value to the number of bits in a megabit (mb). are they the same or different? if there is a difference or uncertainty, explain why that is the case. cite your sources.
