BCD Code
A number with k decimal digits willrequire 4k bits in BCD Decimal 396is represented in BCD with 12bits as
0011 1001 0110 with each group of4 bits representing one decimal
digitA decimal number in BCD is thesame as its equivalent binarynumber only when the number isbetween 0 and 9 A BCD numbergreater than 10 looks different fromits equivalent binary number eventhough both contain 1s and 0sMoreover the binary combinations
1010 through 1111 are not used andhave no meaning in BCD

ASCII CHARACTER CODE
American Standard Code for Information Interchange (Refer to Table 17)
A popular code used to represent information sent as character-based data It uses 7-bits to represent 94 Graphic printing characters 34 Non-printing characters Some non-printing characters are used for text format
(eg BS = Backspace CR = carriage return) Other non-printing characters are used for record marking and flow control (eg STX and ETX start and end text
areas)

ERROR DETECTION CODE
Error-Detecting Code To detect errors in data communication and processing an
eighth bit is sometimes added to the ASCII character to indicate its parity A parity bit is an extra bit included with a message to
make the total number of 1s either even or odd Example Consider the following two characters and their even and
odd parity
