20971520 Bytes are in 20 MB.
21 bits.
One nibble, or nybble, is equal to four bits.
In theory, 3 bits are enough to represent up to 8 (23) combinations.In theory, 3 bits are enough to represent up to 8 (23) combinations.In theory, 3 bits are enough to represent up to 8 (23) combinations.In theory, 3 bits are enough to represent up to 8 (23) combinations.
Because the people who decided to name them bits decided that 8 bits makes up a byte. It is just like asking why is a knife called a knife no real reason.
The subnet mask itself is an IP Address so it is also 32 bits
loosers you stupid suckers
One byte equals eight bits.
Thirty bits make up the network portion of a class C address. Three bits are borrowed for the subnet mask. There is also a class A and a class B that are comprised of bits.

Finishing up with some math, I got somewhere around 1048576 bits in 1 single megabit.
5 bits are necessary to create up to 30 subnets.
1 MB= 1024 KB * 1024 BYTES = 1048576 Bytes as we know 8 bits = 1 byte so 1048576 bytes=1048576*8=8388608 bits. so 1MB=8388608 bits
