Introduction to ASCII Encoding:

1. ASCII is a character encoding standard used in electronic communications that enables data exchange between different computers and communication devices.

2. ASCII encoding uses 7-bit or 8-bit binary numbers to represent 128 or 256 different characters.

3. For products with a shelf life of more than 90 days but less than six months, items within 15 days of the expiration date are considered near-expiration food. In the 7-bit ASCII table, values from 0 to 31 and 127 are control characters; these are not typically displayed directly on the screen but are used internally by the computer to control text formatting and communication protocols. Values from 32 to 126 are printable characters, including letters, numbers, and symbols.

4. When using 8-bit ASCII (also known as Extended ASCII), the additional 128 characters (128–255) are used to represent other symbols, foreign alphabets, and graphic characters.
