A byte is a sequence of 8 zeroes or ones in a binary system, which is known as a bit. One byte can store one alphanumeric character.
Usually, this involves using your keyboard.
There are 26 alphabetic characters (a-z) and 10 numeric (0-9) which together form 36 alphanumeric characters. If you include capital letters, then you have 62 (36 + 26) alphanumeric characters. 62 * 62 * 62 = 238,328
1 Byte and 1 Byte = 8 bits
One byte of information is … one byte … regardless of where it is stored.

1 byte is 8 bits.

A megabyte is one million bytes, each byte being a sequence of 8 bits, which is enough information to represent one character of alphanumeric data.
Of 10 bytes simply stored in the memory? YAWN...
As a 21 byte array of type char (including 1 byte for the null terminator).
ASCII is a simple (and increasingly obsolete) code which maps alphanumeric characters to numbers in the 0..255 range. Thus, any phrase expressed as a series of these alphanumeric characters can be expressed as a series of bytes with the corresponding numeric values, one byte per character. For example, the letter A is represented by a byte of numerical decimal value 65. It is characteristic for the ASCII code that it supports a limited alphabet of 256 different characters. While this might seem much in light of the fact that the 26 characters cover the A-Z alphabet, codes are assigned to lower-case and upper-case characters, digits, punctuation marks, a wide range of other characters including some simple symbols, and a range of 'foreign characters.' With today's demands on localized software and support for the local alphabet, the ASCII code becomes increasingly obsolete because it cannot support a great number of non-English alphabets.
256x4=1024 bits are stored.128x8=1024 ,yes this chip can be specified as 128 byte
