Answer:
Number conversion between hexadecimal and binary involves converting a hexadecimal number to its binary equivalent or vice versa. Binary arithmetic involves performing addition or subtraction operations on binary numbers. Binary-coded decimal (BCD) conversion is a way of representing decimal numbers using binary digits.
Hexadecimal to Binary Conversion:
To convert the hexadecimal number BC57 to binary, replace each hexadecimal digit with its 4-bit binary representation and combine the binary representations: BC57 = 1011 1100 0101 0111.
Binary to Hexadecimal Conversion:
To convert the binary number 10101010010101 to hexadecimal, split the binary number into groups of 4 bits, replace each group of 4 bits with its hexadecimal equivalent, and combine the hexadecimal digits: 10101010010101 = AA55.
Binary Arithmetic:
1) 10111 + 1001 = 100000
2) 110101 - 11010 = 99511
BCD Conversion:
To convert the decimal number 6370 to BCD, replace each decimal digit with its 4-bit BCD code and combine the BCD codes: 6370 = 0110 0011 0111 0000.
To convert the BCD number 10010110010001 to decimal, split the BCD number into groups of 4 bits, replace each group of 4 bits with its decimal equivalent, and combine the decimal digits: 10010110010001 = 9641.
