Numeric and alphabetic characters in ASCII-8 notation along with their Hexadecimal equivalent. Solution: B = 1000010 in ASCII-7 binary notation O = 1001111 in ASCII-7 binary notation Y = 1011001 in ASCII-7 binary notation Hence, the binary coding for the word BOY in ASCII-7 will be 1000010/B 1001111/O 1011001/Y Since each character in ASCII-7 requires one byte for its representation and there are 3 characters in the word BOY, 3 bytes will be required for this representation. Example 4.8. Write the hexadecimal coding for the word GIRL in ASCII-7. required for this representation? Solution: G = 47 in ASCII-7 hexadecimal notation I = 49 in ASCII-7 hexadecimal notation R = 52 in ASCII-7 hexadecimal notation L = 4C in ASCII-7 hexadecimal notation How many bytes are Hence, the hexadecimal coding for the word GIRL in ASCII-7 will be 47/G 49/I 52/R 4C/L = GIRL Since each character in ASCII-7 requires one byte for its representation and there are 4 characters in the word GIRL, 4 bytes will be required for this representation. Example 4.9. Write the binary coding for the word SKY in ASCII-8. How many bytes are required for this representation? Solution: S = 10110011 in ASCII-8 binary notation K = 10101011 in ASCII-8 binary notation Y = 10111001 in ASCII-8 binary notation Hence, the binary coding for the word SKY in ASCII-8 will be 10110011/S 10101011/K 10111001/Y = SKY Since each character in ASCII-8 requires one byte for its representation and there are 3 characters in the word SKY, 3 bytes will be required for this representation. Example 4.10. Write the hexadecimal coding for The word STAR in ASCII-8. How many bytes are required for this representation? Solution: S = B3 in ASCII-8 hexadecimal notation T = B4 in ASCII-8 hexadecimal notation A = Al in ASCII-8 hexadecimal notation R = B2 in ASCII-8 hexadecimal notation Hence, the hexadecimal...
