Any time you press a key on the keyboard, it is saved in memory as 8 bits of 0's and 1's. The more popular code used is called ASCII (American Standard Code for Information Interchange) pronounced As-key. There are tables which show the equivalent of each character in binary. To save space, the binary is converted into Hexadecimal and decimal
Problem: page 116. No. 34. Decode the following:
1001001 0100000 1001100 1001111 1010110 1000101 0100000 1011001 1001111
1010101 0101110
Solution: Converting the Binary code to Hexadecimal
yields 49 20 4C 4F 56 45 20 59 4F 55 2E. Using Fig. 2.41 on page
110, this yields I LOVE YOU.
