Convert hexadecimal numbers to ASCII and vice versa

Hexadecimal and ASCII

Hexadecimal and ASCII are two significant encoding systems used in the world of computers. While they might seem very different at first glance, they can be related to each other by the way computers encode and decode data.

Hexadecimal

Hexadecimal, also known as hex, is a base 16 numbering system. It uses sixteen distinct digits, usually the numbers 0 to 9, followed by the letters A to F, where A corresponds to 10, B to 11, up to F, which corresponds to 15. This system is very handy in computing because it offers an efficient way to represent binary numbers, which computers internally work with. Each hexadecimal digit can exactly represent four binary bits, making it a compact way to denote binary numbers.

ASCII

ASCII (American Standard Code for Information Interchange) on the other hand, is a character encoding used to encode text in computers and other devices that use text. ASCII uses 7 bits to represent 128 unique characters. These characters include the English letters in both upper and lower cases, digits, punctuation, and a number of control codes. The numeric values assigned to each ASCII character are called ASCII values.

A conversion from hexadecimal to ASCII is often used in programming and data analysis, for example when reading data stored in binary or hexadecimal form. The hexadecimal value is first converted to a decimal value, which is then used to look up the corresponding ASCII character.

On the other hand, a conversion from ASCII to hexadecimal is often used when storing or transmitting text data. Each ASCII character is converted into its numeric value, which is then converted to a hexadecimal value for compactness.

The ability to convert between these encoding systems is essential for many aspects of programming and data analysis, and is a fundamental skill in computer science and information technology.
