Bytes
" Byte " - unit of information storage . One byte = grouping of 8 bits e . g . 0 1 0 1 1 0 1 0 One Byte can store one letter , e . g . ' A ' or ' x ' The memory of all storage devices like RAM , hard drives ; flash drives are measured in Bytes , despite being very different hardware . The storage capacities are mentioned in : Kilobyte , KB , about 1 thousand Bytes Megabyte , MB , about 1 million Bytes Gigabyte , GB , about 1 billion Bytes Terabyte , TB , about 1 trillion Bytes

n
In general , for every subsequent Bits , double is the number of patterns of the previous one . 1 bit - 2 patterns , 2 bits – 4 , 3 bits – 8 , 4 bits – 16 , 5 bits – 32 , 6 bits – 64 , 7 bits – 128 , 8 bits - 256 - Mathematically : n bits yields 2n patterns ( 2 to the nth power ) 1 byte is group of 8 bits . 8 bits can make 256 different patterns . One Byte - 256 Patterns The red / green / blue image numbers are each stored in one byte
