How many bits in 20 mega bytes?

Answer 1

1 Bit is the smallest recordable state ( Zero or One / ON or Off / High or Low ) 1 Byte is 8 Bits which can represent a number upto 256 ( 2**8) or a character 1 KiloBytes (KB) is 2**10 Bytes == 1024 Bytes //// "Slang" as One Thousand 1 MegaBytes (MB) is 2**20 Bytes = 2**10 * 2**10 Bytes 1,045,876 Bytes //// "Slang" as One Million 1 GigaByte (GB) is 2**30 == 1,073,741,824 //// "Slang" as One Billion So 20 Gigabytes is 20 * 2**30 Bytes 1 TeraByte (GB) is 2**40 == 1,099,511,627,776 //// "Slang" as One Trillion From the above, you can see why a 32 bit operating system can address upto 4 GB of memory (2**32 4GB if your computer has 4GB of RAM and a 32 bit OS, it will not be able to address it all since some of that address is used by video cards and other devices. This is why most PCs have either 3GB (or less) with a 32 bit OS or MORE & MORE ( 4+GB with 64 Bit OS)

Answer 2

8 bits=1 byte, 1024 bytes=1 kilobyte, 1024 kilobytes=1 megabyte.

So the way to solve this is to do this: 8x1024x1024x20.

This equals 167,772,160 bits in 20 megabytes.

Hope that helps!

Answer 3

The simple answer is 20 thousand bytes.

However this usually actually uses the binary thousand of 1024 instead of the decimal thousand of 1000. Therefor 20 KB usually means 20480 bytes.

Answer 4

There are 1024 bytes in one kilobyte and 1024 kilobytes in one megabyte so the correct number of bytes in 20MB is 20,971,520B.

Answer 5

megabytes is a measure of data not a measure of time. if it is a video file it depends on the video compression and could be almost anything

Answer 6

well, if theres 1000 mb in 1 gb, then just multiply 1000 by 20... you're talking about gigs and MB and yet dont know how to multiply?

Answer 7

20 megabytes is 20,971,520 bytes.
