‣ ASCII stands for American Standard Code for Information Interchange. Computers can only understand numbers, so an ASCII associates an integer value for each symbol in the character set, such as letters, digits, punctuation marks, special characters, and control characters.
The ASCII characters and their decimal code values are shown below. The ASCII table has 128 characters, with values from 0 to 127. Thus, 7 bits are sufficient to represent a character in ASCII; however, most computers typically reserve 1 byte, (8 bits), for an ASCII character.
One byte allows a numeric range from 0 to 255 which leaves room for growth in the size of the character set, or for a sign bit. Consequently, a character data type may optionally represent signed values; however, for now, we will assume that character data types are unsigned, i.e. positive integer values, in the range of 0-127. But, ASCII is a computer code that is similar to binary. Instead of using 1's and 0's like binary it uses the numbers from.
