BINARY CODES TEST THIS WEEK! REVIEW CLASS WEDNESDAY Objectives In this lesson, you will study: 1. Several binary codes including Binary Coded Decimal (BCD), Error detection codes, Character codes 2. Coding versus binary conversion. Binary Codes for Decimal Digits Internally, digital computers operate on binary numbers. When interfacing to humans, digital processors, e.g. pocket calculators, communication is decimal- based. Input is done in decimal then converted to binary for internal processing. For output, the result has to be converted from its internal binary representation to a decimal form. To be handled by digital processors, the decimal input (output) must be coded in binary in a digit by digit manner. For example, to input the decimal number 957, each digit of the number is individually coded and the number is stored as 1001_0101_0111. Thus, we need a specific code for each of the 10 decimal digits. There is a variety of such decimal binary codes.

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
