CHAPTER 2 Data Representation in Computer Systems
If the 4-bit binary value 1101 is unsigned, then it represents the decimal value 13, but as a signed two’s complement number, it represents -3. • C programming language has and unsigned intint as possible types for integer variables. • If we are using 4-bit unsigned binary numbers and we add 1 to 1111, we get 0000 (“return to zero”). •

Chapter 6 Data Type
www2.southeastern.edu– Traditionally, the most commonly used coding was the 8-bit code ASCII (American Standard Code for Information Interchange). – A 16-bit character set named Unicode has been developed as an alternative. – Java was the first widely used language to use the Unicode character set. Since then, it has found its way into JavaScript and C#.

A thumbwheel switch is one example of an input device that uses BCD. The binary numbers are broken into groups of four bits, each group representing a decimal equivalent.
