What is an MB?

Answer 1

a megabyte(mb) is a memory unit equal to 1000 kilobytes(kb)

these memory mesurements range from bytes to zetabytes.

1000 bytes=1 kilobyte(kb)

1000 kilobytes=1 megabyte(mb)

1000 megabytes=1 gigabyte(gb)

1000 gigabytes=1 terabyte(tb)

1000 terabytes=1 petabyte(pb)

1000 petabytes=1 exabyte(eb)

1000 exabytes=1 zetabyte(zb)

but there things called binary bytes.and binary bytes are the same as the above

except these units are measured in a way that is easier to calculate in binary.

binary uses only the numbers 1 and 0 and can create massive amounts

of numeretical values.but 1 and 0 are only indications of yes or no.for instance

if you want the number 8 it would be 1000 because by placing a one you are indicating that you want the number corresponding to that digit.example

____________________________________________________________________

digit 1=1

digit 2=2

digit 3=4

digit 4=8

____________________________________________________________________

so by placing a 1 on the 4th digit i am indicating i want 8.i will show you all digits up to 1024.

____________________________________________________________________

1

2

4

8

16

32

64

128

256

512

1024

____________________________________________________________________

notice these are all numbers doubled by 2. 512x2=1024.

ok now that you understand basic binary you can understand binary bytes.

____________________________________________________________________

1024 bytes=1 kb

1024 kb=1 mb

1024 mb=1 gb (and so on)

____________________________________________________________________

the reason a binary byte is mesured this way is because 1024 is easy to calculate

in binary(computer language)because it would be only one calculation.1024=10000000000.so digit 11 is 1024 in binary and by placing a one there

i am indicating that i want that number.

and remember binary is read from right to left.
